Abstract
A composition comprising a metal oxide and a promoter, wherein at least a portion of the promoter is present as a reduced valence promoter, and methods of preparing such composition are disclosed. The thus-obtained composition is employed in a desulfurization zone to remove sulfur from a hydrocarbon stream.
Claims60
A method for the production of a composition comprising:
- (a) admixing:
- 1) a liquid, 2) a zinc-containing compound, 3) a silica containing material, 4) alumina, and 5) a promoter so as to form a mixture thereof;
- (b) drying said mixture so as to form a dried mixture;
- (c) calcining said dried mixture so as to form a calcined mixture;
- (d) reducing said calcined mixture with a reducing agent under conditions to produce a composition having a reduced valence promoter content therein;
- and
- (e) recovering said composition.

A method for the production of a composition comprising:
- (a) admixing:
- 1) a liquid, 2) a metal-containing compound, 3) a silica-containing material, 4) alumina, and 5) a first promoter so as to form a mixture thereof;
- (b) drying said mixture so as to form a dried mixture;
- (c) incorporating a second promoter onto or into said dried mixture to form an incorporated mixture;
- (d) drying said incorporated mixture so as to form a dried incorporated mixture;
- (e) calcining said dried incorporated mixture so as to form a calcined incorporated mixture;
- (f) reducing said calcined incorporated mixture with a reducing agent under conditions to produce a composition having a reduced valence promoter content therein;
- and
- (g) recovering said composition.
