Increase in Selectivity of Toluene Disproportionation and in p-Xylene Yield by Optimization of Zeolite Microporous Structure

摘要

The possibility of increasing the yield of target products and para-selectivity of toluene dispropor-tionation on modified zeolites by optimization of their microporous structure was studied.Benzene and xylenes (especially p-xylene) are widely used in industry.The main method of the synthesis of the above compounds is alkene dehydrocy-clization.
