Regarding the issue of catalyst cracking feedstock
Thread Content
Does the feed wax oil for catalytic cracking need to be hydrorefined first? I would appreciate the advice from all the teachers!
It’s not necessary; catalytic gasoline only requires hydrorefining
No need; the paraffin oil we have here is divided into reduced-pressure paraffin oil, which is supplied directly after distillation
Hydrorefining of the feed wax oil used in catalytic cracking can reduce the content of polycyclic aromatic hydrocarbons and condensed aromatic hydrocarbons. Demetallization. Desulfurization, denitrification. It can increase the yield of catalytic cracking products and improve product quality. Currently, factories are generally divided into two types: raw material hydrogenation and product hydrogenation.
