|1. (WO2018053890) SUSPENDED BED HYDROCRACKING CATALYST FOR POOR-QUALITY HEAVY CRUDE OIL AND PREPARATION METHOD THEREFOR|
|Applicants:||NATIONAL ENGINEERING RESEARCH CENTER OF CHEMICAL FERTILIZER CATALYST, FUZHOU UNIVERSITY
|Title:||SUSPENDED BED HYDROCRACKING CATALYST FOR POOR-QUALITY HEAVY CRUDE OIL AND PREPARATION METHOD THEREFOR|
The present disclosure relates to the preparation of a suspended bed hydrogenation catalyst, and, in particular, to a suspended bed hydrocracking catalyst for a poor-quality heavy crude oil and a preparation method therefor. The catalyst is prepared by using high-temperature hydrothermally-activated bauxite powder as a carrier and then carrying one or more group VIB and/or group VIII transition metals as an active component. The prepared poor-quality heavy crude oil hydrocracking catalyst produces high catalytic activity and a low coke yield for hydrocracking upgrade of poor-quality heavy crude oils. The feedstock used is easily sourced and has a low price and an environmentally-friendly preparation process, greatly reducing preparation costs of the catalyst and operating costs of the hydrocracking process, and thereby having broad application potential.
