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.

Keywords:

• Zeolites and Zeotypes
• Natural zeolites
• Hierarchical zeolites
• Heterogeneous catalysts
• Bifunctional catalysts
• Zeolytic supports
• Kinetics
• Modelling

Open Access Research Article Synthesis of NaA Zeolite: Conventional Route and Green Route by Antusia dos Santos Barbosa  and Meiry Gláucia Freire Rodrigues Received: 24 October 2023;  Published: 28 January 2024;  doi: 10.21926/cr.2401002 Abstract The research describes a sustainable approach for the synthesis of zeolite NaA using kaolin as an alternative source of silica. The main objective of this research was to prepare NaA zeolite using metakaolin derived from kaolin from the state of Rio Grande do Norte, Brazil, as an alternative source of silica, reducing the production cost and [...]

Open Access Research Article NaY Zeolite Synthesis from Vermiculite and Modification with Surfactant by Thiago Rodrigo Barbosa Barros  , Thianne Silva Batista Barbosa  and Meiry Gláucia Freire Rodrigues Received: 24 October 2023;  Published: 26 December 2023;  doi: 10.21926/cr.2304031 Abstract This work focuses on preparing NaY zeolite using alternative sources of silica and modifying the zeolite with the surfactant cetyltrimethylammonium bromide. Two different hydrothermal synthesis routes were employed: the conventional method using sodium silicate as the silica source, and the other is a sustainable approach using vermiculite [...]

Open Access Research Article Synthesis of SAPO-34 Zeolite Membrane: Influence of Sources of Silica by Tellys Lins Almeida Barbosa  and Meiry Gláucia Freire Rodrigues Received: 03 October 2023;  Published: 11 December 2023;  doi: 10.21926/cr.2304030 Abstract The research described the production and characterization of various materials, particularly alpha-alumina ceramic supports, zeolite SAPO-34, and zeolite membranes. Ceramic supports were manufactured through dry uniaxial compaction. Sintering of the supports was carried out at 1300°C for 2 h. SAPO-34 zeolites and zeolite membranes were s [...]

Open Access Original Research Research and Application of Modified ZSM-5 for the Process of Alkylation of Oil Distillate Fractions by Galina Huseynova  , Nushaba Aliyeva  and Gular Gаsimоvа Received: 20 April 2023;  Published: 10 August 2023;  doi: 10.21926/cr.2303021 Abstract 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 [...]

Open Access Research Article Influence of Bifunctional PtZn/SiO2 and H-ZSM-5 Catalyst on the Rates and Selectivity of Propene Aromatization by Christopher K. Russell  , Arunima Saxena  and Jeffrey T. Miller Received: 28 March 2023;  Published: 06 June 2023;  doi: 10.21926/cr.2302018 Abstract 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 [...]

Open Access Original Research The Effect of Oxygen-containing Additives in Feedstock on the Performance of the Catalytic Cracking Process by Elvira A. Guseinova  and Samira R. Safarova Received: 28 July 2022;  Published: 26 October 2022;  doi: 10.21926/cr.2204037 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 [...]

Open Access Original Research Effect of ZSM-5 Particle Size and Framework Silica-to-Alumina Ratio on Hexane Aromatization by Manal Al-Eid  , Lianhui Ding,  , Donya Sewdan  , Emad N.
