Abstract
Abstract The main industrial methods for the production of styrene and α-methylstyrene are the dehydrogenation of ethylbenzene and isopropylbenzene using mixed oxide catalysts: These reactions are endothermic and reversible, they take place at high temperatures (853–923 K), and their reversibility thermodynamically limits the yields of the products. Displacement of the equilibrium toward the formation of the vinylbenzenes is generally achieved by lowering the partial pressure of the reacting alkylbenzenes by diluting them in steam, heated to 973 K.
期刊介绍：
Catalysis Reviews is dedicated to fostering interdisciplinary perspectives in catalytic science and engineering, catering to a global audience of industrial and academic researchers. This journal serves as a bridge between the realms of heterogeneous, homogeneous, and bio-catalysis, providing a crucial and critical evaluation of the current state of catalytic science and engineering. Published topics encompass advances in technology and theory, engineering and chemical aspects of catalytic reactions, reactor design, computer models, analytical tools, and statistical evaluations.
