Abstract
A catalyst structure includes a porous support structure, where the support structure includes an aluminosilicate material and any two or more metals loaded in the porous support structure selected from Ga, Ag, Mo, Zn, Co and Ce. The catalyst structure is used in a hydrocarbon upgrading process that is conducted in the presence of methane, nitrogen or hydrogen.
Claims20
A method of upgrading a first hydrocarbon product to form a second hydrocarbon product, the method comprising:
- providing a feedstock of the first hydrocarbon product to a reactor;
- and
- reacting the first hydrocarbon product in the reactor in the presence of a gas and a catalyst structure to produce the second hydrocarbon product;
- wherein:
- the catalyst structure comprises a porous support structure comprising an aluminosilicate material, and a plurality of metals loaded in the porous support structure, the plurality of metals comprising at least three metals selected from the group consisting of Ga, Ag, Mo, and Co, wherein each metal loaded in the porous support structure is present in an amount from about 0.1 wt % to about 20 wt % based upon the weight of the porous support structure;
- the gas comprises methane, hydrogen or nitrogen;
- and
- one or more properties of the second hydrocarbon product is changed in relation to the first hydrocarbon product.

A method of upgrading a first hydrocarbon product to form a second hydrocarbon product, the method comprising:
- (a) providing a feedstock of the first hydrocarbon product to a reactor;
- (b) reacting the first hydrocarbon product in the reactor in the presence of a gas and a catalyst structure to produce the second hydrocarbon product;
- (c) after the reacting of the first hydrocarbon product in the reactor in the presence of the gas and the catalyst structure to produce the second hydrocarbon product, regenerating the catalyst structure by performing the following steps:
- rinsing the catalyst structure with toluene;
- drying the rinsed catalyst structure in air to remove toluene from the catalyst structure;
- and
- heating the dried catalyst structure in air at a temperature of at least about 500° C. for a time period of at least about 3 hours to form a regenerated catalyst structure;
- and
- (d) repeating steps (a)-(c) a plurality of times utilizing the regenerated catalyst structure within the reactor;
- wherein:
- the catalyst structure comprises a porous support structure comprising an aluminosilicate material, and any two or more metals loaded in the porous support structure, the two or more metals selected from the group consisting of Ga, Ag, Mo, Zn, Co and Ce, wherein each metal loaded in the porous support structure is present in an amount from about 0.1 wt % to about 20 wt % based upon the weight of the porous support structure;
- the gas comprises methane, hydrogen or nitrogen;
- and
- one or more properties of the second hydrocarbon product is changed in relation to the first hydrocarbon product.
