The Preparation of Modified ZSM - 35 and its Catalysis Effect Analysis on N-Butene Isomerization

In order to study the effect that the modified ZSM - 35 as a catalyst brings to n-butene isomerization catalysis. In this paper, by considering the performance analysis brought by different silica alumina ratio, reaction temperature, concentration of nitrogen and macro porous silica gel embellish acting on butene isomerization reaction of modified ZSM - 35 molecular sieve catalyst , Al2O3 samples being "15" shows better performance; Adding appropriate amount of silicon carbide catalyst or modified silicone can further improve the selectivity of butene; Nitrogen dilution has certain help in improving butene isomerization reaction performance.

Hierarchical aluminum-silicon materials have been successfully prepared by mixing pre-crystallization of silica-alumina sol and citric acid under hydrothermal conditions. The influence of pre-crystallization time on the micro-mesoporous structure is studied using Fourier transform infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD), N2 physical adsorption, and high-resolution transmission electron microscopy (HRTEM). The catalytic performance of hierarchical silica-alumina material is evaluated by alkylation of phenol with tert-butanol. The results show that the silica-alumina materials with a pre-crystallization time of 16 h show micro-mesoporous structure and excellent catalytic activity.
