摘要
氢转移反应是催化裂化过程中十分重要的二次反应 ,是一个低活化能、快速、放热的过程 ,其活化能仅为43 .3kJ/mol。研究表明催化剂的酸结构和孔结构特性、反应温度、焦炭污染状况和反应接触时间能显著地影响催化裂化过程中的氢转移反应 ,决定着裂化产物中的烯烃含量、产物的组成和相对分子质量分布。
Hydrogen transfer reaction is one of the most important secondary reactions in catalytic cracking.It is an exothermic reaction with fast rate and low activation energy.Its activation energy is only 43.3 kJ/mol.Research results showed that both acidic and pore structure of catalyst,reaction temperature,carbionized pollution and reaction contact time have evident influences on hydrogen transfer reaction and determinate the olefin content in cracked product,distribution of the product and the relative molecular weight.
