ChemCatChem, Volume 17, Issue 21, November 10, 2025.Desulfurization in the FCC riser is achieved by modifying zeolite catalysts with La3+ ions, promoting H2S formation from thiophenic compounds while suppressing secondary reactions. This approach enhances gasoline quality by increasing selectivity for H2S and enabling efficient condensation and alkylation, supporting cleaner fuel production and ...

Cs+ and Sr2+ adsorption selectivity of zeolites in relation to radioactive decontamination
Journal of Asian Ceramic Societies, 2015 Zeolites are used as adsorbents of cationic elements in the radioactive decontamination process of water, soil and others. We determined Cs+ and Sr2+ adsorption selectivity of some zeolites to know effective zeolite species for the decontamination of ...

Optimizing Zeolite 13X Synthesis from Kaolin Clay for Higher CO2 Adsorption: A Statistical Approach
ChemCatChem, Volume 17, Issue 22, November 24, 2025.Zeolite 13X is synthesized using kaolin clay as primary raw material through controlled variation of SiO2/Al2O3 ratio; aging time; crystallization temperature; and crystallization time. Statistical analysis identifies the influence of each synthesis parameter on CO2 adsorption capacity.
