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. 考察了多种改性材料的氢转移反应活性及对催化裂化催化剂的重油转化活性及汽油中烯烃含量的影响规律。
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. 鉴于原油加工过程对钙含量的要求，高酸原油并不适于采用自催化直接酯化降酸。
