Carbenium ion

Meanwhile , a carbenium ion mechanism was put forward for the cracking of1,3,5-TIPB .

同时，提出异丙苯和1，3，5-三异丙苯均以正碳离子机理进行裂化的。

High catalyst to oil ratio mainly leads to carbenium ion catalytic reaction , which LPG and coke yields were remarkably increased but dry gas yield was basically unchanged .

由剂油比增加引起的过裂化属于过度催化反应，过裂化点后液化气和焦炭产率出现明显增加的趋势，但干气产率基本上没有变化。
