Abstract
A catalyst composition and a process for using of the catalyst composition in a hydrocarbon conversion process are disclosed. The composition comprises an inorganic support, a Group VA metal or metal oxide, and optionally a Group IVA metal or metal oxide and a Group VIII metal or metal oxide. The process comprises contacting a fluid which comprises at least one saturated hydrocarbon with the catalyst composition under a condition sufficient to effect the conversion of the hydrocarbon to an olefin. Also disclosed is a process for producing the catalyst composition.
Claims53
A composition consisting essentially of an inorganic support and a promoter selected from the group consisting of Group VA metal, Group VA metal oxide, and combinations thereof.
A composition comprising a first catalyst which comprises a first inorganic support, at least one Group IVA metal or metal oxide, and at least one Group VIII metal or metal oxide and a second catalyst which comprises a second inorganic support and at least one Group VA metal or metal oxide wherein said first organic oxide or second inorganic oxide is selected from the group consisting of clays, inorganic oxides, spinels, and combinations of two or more thereof.
A composition comprising a first catalyst which comprises at least one Group IVA metal or metal oxide, at least one Group VIII metal or metal oxide, and at least one first inorganic support;
- and a second catalyst which comprises at least one Group VA metal or metal oxide and a second inorganic support wherein said first or second inorganic support is selected from the group consisting of inorganic oxides, spinels, and combinations of two or more thereof;
- the weight percent of said Group IV metal or metal oxide in said composition is in the range of from about 0.005 to about 3%;
- the weight % of said Group VA metal or metal oxide in said composition is in the range of from about 0.5 to about 40%;
- and the weight % of said Group VIII metal or metal oxide in said composition is in the range of from about 0.005 to about 3%.
A composition comprising:

A process comprising:
- (1) contacting a first inorganic support with at least one Group IVA compound to produce a first composition;
- (2) heat-treating said first composition under a condition sufficient to convert said Group IVA compound to its corresponding oxide to produce a heat-treated first composition;
- (3) contacting said heat-treated first composition with a Group VIII compound to produce a second composition;
- (4) contacting said second composition will heat to produce composition A;
- (5) contacting a second inorganic support with a Group VA compound under a condition sufficient to incorporate said Group VA compound into said third inorganic support to produce a third composition;
- (6) heat-treating said second composition to produce composition B;
- and (7) combining said composition A and said composition B.
A process comprising:
- (1) contacting a first inorganic support with at least one Group IVA compound and at least one Group VIII compound to produce a first composition;
- (2) heat-treating said first composition under a condition sufficient to convert said Group IVA compound and said Group VIII compound to their corresponding oxides to produce composition A;
- (3) contacting a second inorganic support with a Group VA compound under a condition sufficient to incorporate said Group VA compound into said second inorganic support to produce a second composition;
- (4) heat-treating said second composition to produce composition B;
- and (5) combining said composition A and said composition B wherein said first or second inorganic support is selected from the group consisting of clays, aluminas, silicas, spinels, and combinations of two or more thereof.
A process comprising combining composition A and composition B wherein composition A is a platinum- and tin-promoted zinc aluminate and calcium aluminate and composition B is bismuth-promoted silica.
A process comprising contacting a fluid which comprises at least one saturated hydrocarbon with a catalyst composition under a condition sufficient to effect the conversion of said hydrocarbon to an olefin wherein said catalyst composition comprises (1) a first catalyst comprising at least one first inorganic support, at least one Group IVA metal or metal oxide, and at least one Group VIII metal or metal oxide, and (2) a second catalyst comprising at least one Group VA metal or metal oxide and at least one second inorganic support.
A process for converting an aliphatic hydrocarbon to an olefin comprising contacting said aliphatic hydrocarbon with a catalyst composition wherein said contacting is carried out in the presence of steam;
- said catalyst composition comprises a first catalyst which comprises at least one first inorganic support, platinum, and tin and a second catalyst which comprises a second inorganic support and bismuth;
- and said first or second inorganic support is selected from the group consisting of clays, inorganic oxides, spinels, and combinations of two or more thereof.
