Abstract
Chapter 5 surveys the recent advances and forthcoming challenges in aromatics (mainly BTX) preparation from light hydrocarbons. The chapter first summarizes the development history of commercial processes and emerging methods, and introduces the brief principle of light hydrocarbon dehydroaromatization. Then, according to the carbon number of raw materials, the chapter reviews the reaction mechanism and catalyst system of BTX preparation from various light hydrocarbons. Two special sections are devoted to a brief comparison between Zn/HZSM-5 and Ga/HZSM-5 and the deactivation of zeolite and metal–zeolite catalysts used for aromatization. The chapter is concluded with a summary of the research status and a general outlook of challenges in BTX preparation from light hydrocarbons.
