Abstract
|
A conversion
process of hydrocarbon oils comprises at least a hydrodemercaptanization
process, wherein said hydrodemercaptanization process comprises
contacting a feedstock with a hydrofining catalyst containing
a tungsten oxide and/or a molybdenum oxide, a nickel oxide and
a cobalt oxide supported on an alumina under the conditions of
hydrodemercaptanization, in which the content of said tungsten
oxide and /or molybdenum oxide is from 4 wt % to less than 10
wt %, the nickel oxide content is 1 - 5wt %, the cobalt oxide
content is 0.01- 1wt % based on the catalyst, and the ratio of
total atom number of nickel and cobalt to total atom number of
nickel, cobalt, tungsten and/or molybdenum is 0.3 - 0.9. Said
process can be carried out at a lower temperature and a lower
H/oil volume ratio.
