摘要
增产低碳烯烃、轻质芳烃等产物是催化裂解技术发展的趋势,反应条件是影响催化裂解产物分布的关键因素。介绍催化裂解过程涉及的反应机理,概述反应温度、剂油质量比、停留时间(空速)、水油质量比等反应条件,裂解装置和原料油性质对产物收率的影响,结合工业实例分析反应条件对产物收率的影响。
Increasing production of light raw chemical materials such as light olefins and aromatics is an inevitable trend in the development of catalytic pyrolysis technology.Reaction conditions are the crucial factors which affect the catalytic pyrolysis process and product distribution.This review introduces reaction mechanism of catalytic pyrolysis.Some typical reaction conditions including reaction temperature,mass ratio of catalyst to oil,residence time(space velocity),mass ratio of water to oil are being systemically discussed.Additionally,different reactor types and raw oil properties are also under discussion.Finally,we illustrate industrial applications to analyze the effect of reaction conditions.
