Abstract
The present invention provides a method of steam reforming a hydrocarbon over a spinel-containing catalyst at short residence times or short contact times. The present invention also provides spinel-containing catalysts. Surprisingly superior results and properties obtained in methods and catalysts of the present invention are also described.
Claims22
A method of steam reforming, comprising:
- passing steam and hydrocarbon through a reaction chamber;
- wherein the reaction chamber comprises a spinel-containing catalyst that has surface active sites comprising a material selected from the group consisting of rhodium, iridium, nickel, palladium, platinum, ruthenium, carbide of group VIb and combinations thereof;
- wherein the rate of said passing steam and hydrocarbon is controlled such that residence time in the reaction chamber is less than 0.1 seconds;
- wherein the temperature in the reaction chamber is in the range of 500° C. to 1000° C.;
- and wherein, at least 60% of said hydrocarbon is converted to products.
