CLEAN - Soil Air Water · 2023

Abstract Environmental damage ranges from soil degradation, air pollution, and wastewater from human‐induced activity. In this study, to reduce CO2 emission, zeolite granules were prepared manually. In addition, the mass transfer and kinetic adsorption were analyzed to understand the mechanism of CO2 adsorption using mathematical models. We studied the effects of amount of binder, temperature, granule size, and flow rate of CO2 on efficient CO2 adsorption on zeolite 5A granules of different sizes (3–4 and 6–7 mm). The kinetics of CO2 adsorption and mass transfer of zeolite 5A granules were evaluated for the rate‐limiting step. The results showed that decreasing the temperature and the amount of binder increased the CO2 adsorption capacity. We observed the highest CO2 adsorption capacity of 2.84 mmol g−1 at 298 K with 4 wt% of the binder at a flow rate of 2 L h−1. The pseudo‐first‐order sorption behavior was the best model with R2 > 0.9832, whereas the root mean square error model showed an R2 < 0.2136. The Biot number and film diffusion model were used to investigate the importance of external mass transfer on intraparticle diffusion. It was confirmed that the adsorption on sustainable zeolite 5A granules was controlled by film diffusion.

Atmosphere · 2022

The objectives of the research were to develop synthesis and estimation of each factor on carbon dioxide adsorption of advanced functional zeolite NaY material derived from bagasse ash and rice husk ash with different crystallization temperatures and weight percentages of zinc by the ion exchange method. The adsorbents were tested in a packed bed reactor at different temperatures and flow rates of carbon dioxide. The Minitab program was used to estimate the effects of each factor on carbon dioxide adsorption properties. The results showed that extracted silicon dioxide from bagasse ash and rice husk ash could be successfully used as raw material for zeolite NaY synthesis with a crystallization temperature of 298.15 K. The zeolite NaY crystalline structure was well-preserved after ion exchange. The highest capacity of carbon dioxide adsorption was at 10.33 mmol/g with zeolite 5B298-373-1. The results of the Minitab program showed that the carbon dioxide adsorption decreased with increasing crystallization temperature and carbon dioxide flow rate parameters. However, the increased weight percentage of zinc loading on zeolite NaY resulted in better carbon dioxide adsorption. The factors of the types of adsorbents and adsorption temperature showed interaction with each other.

This study focused on a quantitative study of the CO2 adsorption dynamic within the adsorbent particle. It could drive and improve ideal pore characteristics and the adsorption process efficiency. The parameters operating conditions for the CO2 adsorption process of zeolite 5A pellet were studied using Aspen Adsorption. The effects of compression force (200–400 MPa), compression time (5–15 min), and addition of bentonite binder (0–15% wt. of bentonite binder) for zeolite 5A pelletization and temperature for CO2 adsorption ranging from 298–373 K were studied. There was an error from the simulation of approximately 0.34–10.62% compared to the experimental results. The results showed that the interparticle voidage was reduced, and the appropriate mass transfer was required for good CO2 adsorption capacity. Reduction of interparticle voidage is achieved using a small compression force, a short compression duration, and a small bentonite binder, all of which significantly increase CO2 adsorption capacity. The mass transfer must be within the optimum range because it will decrease the contact time between the zeolite surface and the CO2 molecules. The CO2 adsorption increases with the gas phase temperature decrease. The result showed that the maximum CO2 adsorption by zeolite 5A was 7.078 mmol CO2/g with 0 wt% bentonite binder, 200 MPa, and 5 min at 298 K, 1 atm pressure.

Atmosphere · 2022

The objective of this research was to investigate the behavior and conditions for CO2 adsorption using a mixture of CO2/N2 over a fixed-bed column of zeolite 5A. The study was performed with a variation in gas composition of CO2/N2 as a 20/80, 50/50, and 80/20 volume %, the adsorption temperatures as 298, 333, and 373 K and the total feed flow rates as 1, 2, and 4 L/h under 100 kPa pressure. The Bohart–Adams, Yoon–Nelson, and Thomas models were used to predict the breakthrough behavior of CO2 adsorption in a fixed column. Furthermore, the adsorption mechanism has been investigated using the kinetics adsorption of pseudo-first-order, pseudo-second-order, Boyd model, and intraparticle model. Increasing the CO2 composition of a gas mixture resulted in a high CO2 adsorption capacity because of the high partial pressure of CO2. The capacity of CO2 adsorption was decreased with increasing temperature because of physical adsorption with an exothermic reaction. The CO2 adsorption capacity was also decreased with increasing feed flow rates with inadequate time for CO2 adsorbates diffusion into the pores of the adsorbent before exiting the packed bed. The CO2 adsorption by zeolite 5A confirmed that the physical adsorption with intraparticle diffusion was the rate-controlling step of the whole process.

Processes · 2021

The simulation of carbon dioxide (CO2)-methane (CH4) mixed gas adsorption and the selectivity on zeolite 4A using Aspen Adsorption were studied. The influence of temperature ranging from 273 to 343 K, pressure up to 10 bar and various compositions of CO2 in the binary system were simulated. The findings of the study demonstrate that the models are accurate. In addition, the effects of various key parameters such as temperature, pressure, and various compositions of binary gases were investigated. The highest CO2 and CH4 adsorption are found at 273 K and 10 bar in the Langmuir isotherm model with 5.86 and 2.88 mmol/g, respectively. The amount of CO2 adsorbed and the selectivity of the binary mixture gas depends on the composition of CO2. The kinetics of adsorption for pure components of CO2 at high temperatures can reach saturation faster than CH4. The influence of the physical properties of zeolite 4A on kinetic adsorption were also studied, and it was observed that small adsorbent particles, large pore diameter, and large pore volume would enter saturation quickly. The prediction of CO2-CH4 mixed gas adsorption and selectivity on zeolite 4A were developed for further use for commercial gas separation.

Current Applied Science and Technology · 2021

This research investigated the effects of compression force, compression time, and addition of bentonite binder on zeolite 5A pelletization. Carbon dioxide (CO2) adsorption of zeolite 5A pellets was tested in a laboratory-scale packed-bed reactor at 298 K, atmospheric pressure and 2 l/h flow rate. Zeolite 5A pellets were prepared using a pelletization technique at 200-400 MPa compressive force, 5-15 min compression time, and with 0-15% wt. of bentonite binder. The specific surface area and density of zeolite 5A pellets increased with increase of compression force. Compression force led to increase in specific surface area and resulted in an agglomeration of zeolite pellets, making CO2 molecules more difficult to become active sorbent. The addition of bentonite into zeolite 5A pellets with more compression time resulted in the reduction of specific surface area. The compression force and mass fraction of the binder were found to offer significant control over CO2 adsorption capacity. No addition of binder, 200 MPa compression force and 5 min compression time resulted in a maximum CO2 adsorption capacity of 3.64 mmol CO2/g. This research indicated that zeolite 5A pellets have a beneficial effect and high potential as an adsorbent, especially in terms of CO2 adsorption and environmental applications

Zeolite NaA is an excellent adsorbent among other materials but its potential as a carbon dioxide adsorption still needs to be developed. Therefore, this research was to synthesize zeolite NaA from rice husk ash under different temperatures and crystallization times. The synthesized zeolite NaA was modified with zinc by an ion exchange method. Adsorbents were tested for the carbon dioxide adsorption at different operating temperatures and flow rates. The results showed that the zeolite NaA was successfully synthesized from rice husk ash under optimal conditions of the crystallization temperature at 333.15 K and time for 2 h. The zeolite NaA can be synthesized at low crystallization temperature and time resulted in this adsorbent has low cost while achieving high efficiency. The results of zeolite NaA modification with zinc playing a key role to increase the BET surface area, micropore volume and total pore volume resulted in an increase of carbon dioxide adsorption capacity. High carbon dioxide adsorption at 89.08% with the operating temperature at 573.15 K and carbon dioxide flow rate of 1 L/h were shown with 5 wt.% zeolite NaA.

Bagasse ash is one of the agricultural wastes and valuable biomass by-products in sugar milling. It was treated hydrothermally with hydrochloric aqueous solution at 100 °C and burned at 600°C for 2 hours under oxygen feeding. The obtained white ash was further used as natural silica source instead of silica sol because of highly silica content from an abundant supply of sugar industries in Thailand. Aluminosilicate precursor gel was prepared from alumina source and silica source via sodium silicate preparation. Different crystallization time was studied for the molar ratio of SiO2/Al2O3 = 2 at 100°C crystallization temperature. The phillipsite zeolite synthesized was characterized using various techniques; X-ray diffraction, Scanning electron microscopy, Fourier Transform Infrared Spectroscopy, and BET-N2 adsorption method. The results can be used as value added for bagasse ash utilization, minimize the environmental impact of disposal problems and further application for heavy metal removal.

Journal of Nanoscience and Nanotechnology · 2008

A flame aerosol reactor (FLAR) was used to synthesize SiO2-based nanocomposite materials of SiO2-TiO2 in different precursor molar ratios and quench ring positions. Processing conditions were determined that resulted in formation of different crystal phases at different precursor concentration molar ratios. The results showed that the addition of SiO2 inhibited TiO2 phase transformation from anatase to rutile. The different morphology of SiO2-TiO2 nanocomposite was primarily the result of changing the quench ring position. Quenching can stop the growth kinetics, and this was obtained by locating the quench ring at different positions in the particle formation process. At a lower position, a binary mixture of SiO2-TiO2 was obtained in a core–shell structure. The difference in residence time for sintering and coalescence yielded different morphologies of SiO2-TiO2 nanocomposites. The results from FTIR confirmed Si-O-Ti bonding for all samples. The samples of SiO2-TiO2 exhibited better suspension in liquid than pure TiO2 as confirmed by zeta potential measurements.

Environmental Engineering Science · 2008

Elemental mercury (Hg0 ) capture by heterogeneous gas–solid reaction with nanostructured sorbents was studied in a differential bed reactor system at room temperature. Commercially available (four types of iron oxide, titanium dioxide, titania pillared clay) and in-house synthesized (magnetite and SUZ-4 zeolite) sorbents were studied. Elemental mercury capture efficiency greater than 70% was observed for TiO2, TiO2 pillared clay (PILC), SUZ-4 zeolite, and one of the commercial iron oxides on irradiation with UV light for an inlet mercury concentration of 75 ± 1.9 μg/m3. The initial rate of Hg0 capture per unit mass of sorbent was highest for TiO2. The initial capture rates, rinit = kS0 (1-x)CαHg,0, were determined with α values of 1.03, 1.21, 1.19, and 1.51 for TiO2, TiO2 PILC, SUZ-4 zeolite, and one of the commercial iron oxides, respectively. In addition, the rate constants (k) were found to be 2.43×10−17, 4.66×10−19, 3.41×10−20 and 8.6×10−20μg1-α m3α-2 s−1 for TiO2, TiO2 PILC, SUZ-4 zeolite, and one of the commercial iron oxides, respectively. A three-step sequential extraction technique, targeting surface bound, acid-soluble, and encapsulated mercury species, was used to investigate the binding mechanisms and the mobility of mercury. The mercury associated with one of the commercial iron oxides was more labile than the mercury associated with the other sorbents. Titania (TiO2) shows the greatest potential to be used as a sorbent to capture elemental mercury on irradiation with UV light based on the results of this study.
