About the topic:
Dear Colleagues,
Zeolites are crystalline aluminosilicates with an ordered porous network and a unique combination of properties such as high thermal and mechanical stability, well defined pore-size and intrinsic acidity. These materials attract interest due to their wide range of applications, especially as catalysts, where the native active sites or introduced species, such as metals, promote the occurrence of catalytic reactions, inside the pores that act as microreactors. Parallelly, the use of zeolites as supports for active species like organometallic complexes or enzymes has been growing since it allows to transform homogeneous to environmentally friendly and reusable heterogeneous catalysts. The aim of this Special Issue is to promote the discussion concerning the synthesis, modification and functionalization of zeolites and zeotypes, to produce effective and innovative catalysts/catalysts supports for heterogeneous reaction.

Research and Application of Modified ZSM-5 for the Process of Alkylation of Oil Distillate FractionsAbstract In the oil distillate fraction alkylation process, a modified Zr zeolite ZSM-5 was obtained and studied. The modification was executed using a method that impregnated ZSM-5 with a 5% solution of ZrOCl2∙6H2O. X-ray diffraction studies [...] |
Influence of Bifunctional PtZn/SiO2 and H-ZSM-5 Catalyst on the Rates and Selectivity of Propene AromatizationAbstract Previous studies on the conversion of olefins to aromatics with bifunctional Ga- or Zn-ZSM-5 catalysts have concluded that benzene, toluene, and xylenes (BTX) yields are significantly higher than for ZSM-5 alone. These results were attributed to the higher aromatic dehydrogenation rate of Ga or Zn. In this study, a highly active, bifunctional [...] |
The Effect of Oxygen-containing Additives in Feedstock on the Performance of the Catalytic Cracking Processby
![]() ![]() Abstract In this study, we found that adding catalytic cracking feedstock, vacuum gas oil, and naphthenic acids in the amount of 0.005–0.0075% vol. increased the liquid target fractions, i.e., gasoline and light gas oil. The decrease in the yield of hydrocarbon gas at a practically constant degree of conversion of the raw material indicated a small [...] |
Effect of ZSM-5 Particle Size and Framework Silica-to-Alumina Ratio on Hexane Aromatizationby
![]() ![]() ![]() ![]() ![]() ![]() ![]() Abstract Parent ZSM-5 and Ga-modified ZSM-5 catalysts with different Si/Al ratios and particle sizes were prepared. The physicochemical properties of the prepared catalysts were investigated by performing X-ray powder diffraction analysis, BET surface area analysis, and NH3-TPD analysis. The performance of the aromatization react [...] |
Hydrocracking of Di-and Triaromatic Hydrocarbons to Monoaromatics over Mixed Bi-functional CatalystsAbstract In this study, we present selective hydrocracking of poly (di and tri) aromatic compounds to monoaromatics, such as benzene, toluene, and xylenes (BTX), over a mixture of Pt/Al2O3 and Y zeolites. The polyaromatic compounds feed is a combined simulated model feed, which is similar to light cycle [...] |
Zeolite-Containing Catalysts in Alkylation ProcessesAbstract This article provides an overview of zeolite-containing catalysts used in the alkylation of benzene and toluene with olefins, isobutane with butenes and butane-butene fractions, gasoline and oil fractions with olefins, propane-propylene, and butane-butylene fractions of catalytic cracking. Zeolites have various types of structures, including [...] |
Dearomatization of the Kerosene Fraction: Kinetic Studiesby
![]() ![]() Abstract The kinetics of dearomatization of a kerosene fraction processed using a zeolite catalyst (0.9 HZSM-5) at different temperatures (160-200°C), the molar ratio between the aromatic hydrocarbons present in the kerosene fraction and n-decene (1:(0.5-4)), and the reaction time (1-3 h) were studied. Based on the obtained data [...] |
Hierarchical MFI Zeolite Catalysts: How to Determine Their Textural Properties?-A Comparative Studyby
![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() ![]() Abstract It is important to elucidate the role of the surface areas and pore volumes of hierarchical zeolites to understand their behavior as catalysts. Micro-and mesopore surface areas and volumes of the hierarchical MFI (Mobil Five zeolites) were assessed following several methods: (i) N2 adsorption at [...] |
