This review introduces the synthesis of hierarchical Beta zeolite in detail from the two strategies of"bottom-up"(direct synthesis)and"top-down"(post modification). The synthesis of hierarchical Beta zeolite by hard template method,soft template method,mesoporous template method, dealuminization method...
摘要: Hydrocarbon feedstocks such as distillate fuel oils and gas oils are dewaxed by isomerizing the waxy components over a zeolite beta catalyst. The process may be carried out in the presence or absence of added hydrogen. Preferred catalysts have a zeolite silica:alumina ratio over 100:1....
In this study, nitrogen-doped activated carbon (NAC) and Beta zeolite were synthesized from residual carbon (RC) and fine slag (FS), which were separated from coal gasification fine slag (CGFS) through flotation. These materials were used in tandem catalytic pyrolysis of cow manure (CM) to ...

In dealuminated samples two new lines associated with SiOH have been identified in 29Si NMR spectra, the first assigned to structural sites, part of them occupied by Al in the starting zeolite, and the second associated with the amorphous material produced during calcination. 展开 ...
Mesoporous Beta Zeolite-Supported Ruthenium Nanoparticles for Selective Conversion of Synthesis Gas to C-5-C-11 Isoparaffins Mesoporous beta (meso-beta) zeolites prepared by post-treatment of H-beta with NaOH aqueous solution were studied as supports of Ru catalysts for Fischer-T... 王野 被引量...

A template free synthesis route was developed for the synthesis of hierarchical zeolite Beta from a natural layered aluminosilicate mineral kaolin. Detailed study on the crystallization of zeolite Beta established the optimized synthesis condition, and the synthesized hierarchical Beta zeolite was fully stud...
