Process for upgrading shale oil

摘要

A process for hydrocracking a hydrocracking feedstock with hydrogen at hydrocracking conversion conditions which comprises contacting the feedstock with a first catalyst comprising a nickel component, a molybdenum component and a phosphorus component deposited on a support component consisting essentially of a refractory metal oxide, and a second catalyst comprising a cobalt component, a chromium component and a molybdenum component deposited on a support component consisting essentially of a refractory metal oxide component and a molecular sieve component. This process is particularly suitable for the hydrocracking of shale oil feedstocks which typically have high nitrogen contents, i.e., total nitrogen at least about 0.2 wt %.
