The hydrogen transfer activities of several modified materials were investigated and co related with the heavy oil catalytic cracking ability and olefin content in cracked naphtha. 考察了多種改性材料的氫轉移反應活性及對催化裂化催化劑的重油轉化活性及汽油中烯烴含量的影響規律。
However, it is unsuitable to adopt the autocatalytic esterification for reducing acid content of high acid crudes due to the limitation of calcium content in crude oil processing. 鑒於原油加工過程對鈣含量的要求，高酸原油並不適於採用自催化直接酯化降酸。
