催化剂对重油悬浮床中压加氢工艺的影响研究

A Study on the Slurry Bed Hydrocracking Process of Extra Heavy Oil at Catalyst

以胜利重油为原料,采用间歇式反应考察催化剂对重油悬浮床中压加氢裂化反应的影响。研究发现镍铁分散型催化剂中活性金属具有很强的加氢活性,可使大量的自由基加氢饱和,抑制反应过程中自由基的缩合,即分散型镍铁催化剂具有比较好的加氢和抑制生焦性能。

The victory of heavy oil as raw material, the batch reactor is studied the impact of pressure hydro- cracking catalyst for heavy oil suspension bed in. The study found that active metal has a strong hydrogenation ac- tivity of nickel-iron dispersed catalyst, allows the number of free radicals hydrogenation saturated, inhibition of free radicals in the reaction process of condensation, that is dispersed nickel-iron catalyst has a relatively good hydro- genation and inhibition of coke performance.
