Preparation of composite catalyst and its catalytic cracking properties of coal tar

Abstract

Abstract China is rich in coal resources. Coal tar produced by coal combustion is a large amount of surplus. Naphtha and diesel oil with similar properties to kerosene and diesel oil can be produced by catalytic cracking of coal tar oil. In this article, metal-loaded UiO-66 and Y-type zeolite were synthesized by solution thermal method and microwave assisted method. And a high temperature resistant active component catalyst UiO-66-Y was prepared by compounding the two. According to the GC-MS characterization of the original coal tar and the products after cracking with UiO-66-Y, the results show that part of the aromatic compounds in the coal tar added with catalyst will be decomposed and a large number of light component esters will be synthesized at the same time. It provides a possible way to solve the current energy dilemma.
