Method for producing raw materials for a reformer by cracking and desulfurizing petroleum fuels

Claim 1

A method for producing raw materials for a steam reformer in a fuel cell electricity generation process which comprises: providing in combination, a desulfurzier, an adsorber; a steam reformer, a converter or gas separation membrane, and a fuel cell, and desulfurizing and cracking petroleum fuel in the desulfurizer using a metallosilicate catalyst having a Si/Al atomic ratio of 40-3200 at a temperature of 300°-600° C., a pressure of 1-10 kg/cm 2 , H 2 /oil ratio of 500-2000, and an SV of 0.5-4 hr -1 . wherein in said steam reformer, said desulfurzied and cracked fuel reacts with steam and is converted to product-gas comprising hydrogen, carbon monoxide, and carbon dioxide.

Claim 2

A method for producing raw materials for a steam reformer in a fuel cell electricity generation process which comprises: providing in combination, a desulfurzier, an adsorber; a steam reformer, a converter or gas separation membrane, and a fuel cell, and desulfurizing and cracking petroleum fuel in the desulfurizer using a metallosilicate catalyst having a Si/Al atomic ratio of 40-3200 at a temperature of 300°-600° C., a pressure of 1-10 kg/cm 2 , H 2 /oil ratio of 500-2000, and an SV of 0.5-4 hr -1 . wherein in said steam reformer, said desulfurzied and cracked fuel reacts with steam and is converted to product-gas comprising hydrogen, carbon monoxide, and carbon dioxide.

Claim 7

A method for producing raw materials from a steam reformer in a fuel cell electricity generation process which comprises: providing, in combination, a desulfurizer, an adsorber, a steam reformer, a converter or gas separation membrane, and a fuel cell, desulfurizing and cracking fuel comprising kerosene, naphtha or liquified petroleum gas in said desulfurizer in the presence of a metallosilicate catalyst having an atomic ratio Si/Me of 40-3200, wherein Me is a metal selected from the group consisting of Al, Ni, Co, Mo, W, Fe, Cr and Ga, at a temperature of 300°-600° C., a a pressure of 1-10 kg/cm 2 , a H 2 /oil ratio of 500-2000, and an SV of 0.5-4 hr -1 whereby the desulfurized product contains ≦ 1 ppm sulfur, introducing said desulfurized product into said reformer wherein said product comprises C 3 to C 20 hydrocarbon and has a specific gravity of 0.5 to 0.85, steam reforming said product in said steam reformer wherein said product reacts with steam and is converted to product-gas comprising hydrogen, carbon monoxide, and carbon dioxide, and reducing the carbon monoxide content of the product-gas from said steam reformer to ≦ 1 vol. %.

Claim 8

A method for producing raw materials from a steam reformer in a fuel cell electricity generation process which comprises: providing, in combination, a desulfurizer, an adsorber, a steam reformer, a converter or gas separation membrane, and a fuel cell, desulfurizing and cracking fuel comprising kerosene, naphtha or liquified petroleum gas in said desulfurizer in the presence of a metallosilicate catalyst having an atomic ratio Si/Me of 40-3200, wherein Me is a metal selected from the group consisting of Al, Ni, Co, Mo, W, Fe, Cr and Ga, at a temperature of 300°-600° C., a a pressure of 1-10 kg/cm 2 , a H 2 /oil ratio of 500-2000, and an SV of 0.5-4 hr -1 whereby the desulfurized product contains ≦ 1 ppm sulfur, introducing said desulfurized product into said reformer wherein said product comprises C 3 to C 20 hydrocarbon and has a specific gravity of 0.5 to 0.85, steam reforming said product in said steam reformer wherein said product reacts with steam and is converted to product-gas comprising hydrogen, carbon monoxide, and carbon dioxide, and reducing the carbon monoxide content of the product-gas from said steam reformer to ≦ 1 vol. %.
