使用铁／沸石系催化剂的重油加氢裂化过程研究了常压渣油使用铁／沸石系催化剂及ＵＳＹ催化剂时的加氢裂化活性。结果证明：用低ＰＨ值硝酸铁水溶液制备的铁／沸石催化剂具有优良的加氢裂化活性，与ＵＳＹ催化剂相比，铁／沸石催化剂寿命长。还研究了铁的载持状态对催化剂...
Hydrocracking activity of heavy oil for iron / zeolite catalysts using iron / zeolite catalyst for iron / zeolite catalysts and USY catalyst was investigated. The results demonstrate that iron / zeolite catalysts prepared with a low pH aqueous ferric nitrate solution have excellent hydrocracking activity and a longer iron / zeolite catalyst life than USY catalysts. Also studied the state of support of iron on the catalyst ...
