A HIGHLY ACTIVE MIDBARREL HYDROCRACKING CATALYST AND THE PREPARATION THEREOF

摘要

The present invention mid-barrel (midbarrel) of high activity relates to a hydrocracking catalyst and its manufacturing process. The first support (support) the catalyst comprises a modified zeolite -Y, -β modified zeolite, alumina and the like. A composite of the modified zeolite and zeolite -Y -β shows the catalytic effect has good synergy. The catalyst is prepared by supporting with ⅥB group (group) and / or Ⅷ group metal components are useful in the hydrocracking process of heavy oil (heavy oil) having a high sulfur and nitrogen content to produce a high quality heavy crude oil for the maximum yield Do. The activity and selectivity of the catalyst for a heavy oil is promoted at the same time considerably. Furthermore, this is significantly reduced significantly the freezing point of diesel production. ; Hydrocracking step (hydrocracking), the catalyst, the catalyst support, -Y zeolite, zeolite -β, heavy crude oil, heavy fuel oil (heavy oil), the mid-barrel (midbarrel), micropores porous alumina
