重整抽余油催化加氢制优质溶剂油

Preparation of High-grade Solvent Naphtha from Reformed Raffinate through Hydrogenation

在低压条件下进行了重整抽余油加氢脱不饱和烃制优质溶剂油的试验。Pt／Al_2O_3催化剂在该反应中表现出优良的低压加氢反应活性和稳定性，经加氢处理后，重整抽余油中的烯烃转化率和芳烃转化率分别可达99％和95％以上。

Experiments were carried out under low hydrogen pressure upon the hydrogenation of reformedraffinate to remove unsaturated hydrocarbons and obtain high-grade solvent naphtha. The selected cata-lyst Pt/Al2O3 exhibited good activity and stabilty under selected reaction conditions. After hydrogena-tion, 99% alkene and 95% aromatics in re formed raffinate were converted, respectively.
