Abstract
This invention relates to a catalyst for hydrotreatment of hydrocarbons comprising one or more of metals selected from the group consisting of transition metals and metals of group IIb of the periodic table supported on sepiolite. More particularly it relates to a catalyst effective in the selective demetallization treatment of hydrocarbons.
Claims35
A hydrodemetallization catalyst comprising an effective amount of a catalyst metal component supported on a sepiolite carrier, the catalyst metal being selected from the group consisting of Mo, W and V.
A hydrodemetallization catalyst comprising an effective amount of catalyst metal components supported on a sepiolite carrier, the catalyst metal being
- (1) at least one member selected from the group consisting of Co., Ni, Fe, Cu and lanthanides and
- (2) at least one member selected from the group consisting of Mo, W and V.
A sepiolite carrier prepared according to a process comprising:
- (a) grinding sepiolite to a fine powder, 50% or more by weight of which has a particle size of 100-mesh or finer;
- (b) adding water to the sepiolite obtained in (a) to adjust the water content thereof to about 20 to about 350% by weight;
- (c) kneading the resulting mixture in (b), and subsequently
- (d) air-drying or heat-treating the resulting mixture in (c) at a temperature lower than about 1000.degree. C.
A hydrodemetallization catalyst comprising an effective amount of one or more catalyst metal components supported on sepiolite, the catalyst metal being selected from the group consisting of the metals of the IIb group and the transition metals of the Periodic Table, and wherein said catalyst is prepared according to a process comprising the steps of:
- (a) grinding sepiolite to a fine powder, 50% or more by weight of which has a particle size of 100-mesh or finer;
- (b) adding water to the ground sepiolite to adjust the water content thereof to about 20 to about 350% by weight;
- (c) kneading the resulting mixture;
- (d) air-drying or heat-treating the moist kneaded sepiolite at a temperature lower than about 1000.degree. C.;
- and
- (e) supporting one or more of said catalyst metal components on the sepiolite, the sequence of steps being (a), (b), (c), (d), and (e) or (e), (a), (b), (c) and (d).
