查询词典 gas oil

The experiments for determining the mechanism and kinetics of catalytic pyrolysis reaction for a simple petroleum feedstock, were carried out in a batch micro-reactor using Daqing light gas oil. The results showed that carbonium and free radical reactions were the key reactions in catalytic pyrolysis. The carbonium ions were induced by catalytic reaction, whereas free radical reaction was predominantly due to thermal cracking.

首先在重油微反装置上考察大庆减压馏分油催化裂解反应产品分布，并将反应结果与相同温度范围内的热裂解反应相比较，二者的产品分布随温度等操作参数的变化规律明显不同，进而推断催化裂解反应过程为正碳离子反应机理和自由基反应机理并存；并建立了大庆减压馏分油催化裂解消失动力学模型，求得了化学反应速率常数。
