ZEOLITE ZSM-5 (ref. 1) is a member of a new class of shape selective catalysts with unique channel structures which differ from the familiar large-pore faujasite and small-pore zeolites such as Linde Type A and erionite. They also possess unusual catalytic properties and have high thermal ...
Zeolite with a structural feature as small as the size of a unit cell (5–10nm) with hierarchically ordered porous structure would be very promising for catalysis. 展开 关键词: mesoporous materials nanostructures solid acid catalysts structure‐directing agents zeolites ...
The present study reports a design of a unique holder for modifying the structure of ZSM-5 zeolite using electron beam generated from an industrial UERL-10-15S2 linear accelerator with a fixed energy of 10MeV. The design was made based on a unique holder, named EDSC holder, which can be...
The siting of AI and of bridging OH groups in zeolite HZSM-5 is studied by defect energy minimization adopting the classical shell model. The small energy differences between the various lattice sites suggest that there would be little deviation from a random distribution of bridging hydroxyl group...
High structure-directing activity and specificity of templating action of tetrapropylammonium cations TPA+ as well as high concentration of framework-forming substances in the initial reaction mixtures contribute to the formation of zeolite ZSM-5 at relatively low temperature (100 °C) in the alkali...

ZSM-5 zeolite prepared by template-free method and solid-like-state conversion method.The composition and homogeneous dispersion of the starting material play a decisive role in the crystallinity of the product.Scale-up production of highly crystalline ZSM-5 zeolite can be achieved in the laboratory...
The process of hydrogen-free upgrading of diesel fraction on ZSM-5 type zeolite catalyst was implemented at the laboratory catalytic unit under the conditions of varying the process temperature. The composition and characteristics of the feedstock diesel fraction and the obtained upgrading products were...
