摘要
蒸汽裂解是指石油烃类如乙烷或石油馏分如石脑油、瓦斯油等在高温和水蒸气存在的条件下发生分子断裂和脱氢反应的过程,其主要目的是制备乙烯、副产丙烯、丁二烯等低分子烯烃产品。蒸汽裂解方法是为化学工业提供基础化学品的主要途径,其过程中所使用的催化剂对提高蒸汽裂解的效率起着至关重要的作用。本文对催化蒸汽裂解中所使用的催化剂进行了综述。
Steam cracking refers to a reaction which use hydrocarbon such as ethane or petroleum distillates such as naphtha,gas oil as reactant,and dehydrogenate,moleculars crack at high temperature and presence of water vapor,the process＇ s main purpose is to prepare ethylene,byproduct propylene,butadiene or other short chain olefin.Steam cracking is the main course to provide basic chemicals in chemical industry,the use of catalyst is of great importance to the increase of efficiency in steam cracking.The catalysts used in steam cracking were summarized.
