Abstract
|
A hydrotreating
catalyst containing molybdenum and/or tungsten for light oil distillates,
said catalyst contains tungsten oxide and/or moybdenum oxide,
nickel oxide and cobalt oxide supported on an alumina carrier,
the content of said tungsten oxide and/or molybdenum oxide is
from 4wt% to less than 10wt%, the content of nickel oxide 1- 5wt%,
the content of cobalt oxide 0.01- 1wt%, the atom ratio of nickel-cobalt
to nickel, cobalt-tungsten and/or molybdenum is 0.3 - 0.9. Compared
with the prior art, the catalyst has lower metal content, but
higher activity at low-temperature. The catalyst is especially
suitable for use in the hydrodemercaptanization process of light
oil distillates.
