Abstract
Catalysts particularly useful for hydroreforming and isomerization of hydrocarbons formed of a refractory mineral oxide carrier having a halogen in combined form and the following metals in free or combined state: (a) A metal from the platinum group (0.02 to 2%); (b) tin (0.02 to 2%); and (c) at least one metal selected from the group of scandium, yttrium, thorium, uranium, and the rare earths metals (0.01 to 5%)--said percentages being based upon the total weight of the catalyst, said catalyst preferably having platinum and chlorine. Also the use of said catalyst in the aforementioned hydrotreatments.
Claims12
A method comprising use of a catalyst in the reforming, in the presence of hydrogen, of hydrocarbon fractions whose sulfur content is under 10 ppm and whose boiling temperature at atmospheric pressure is between 35.degree. and 250.degree. C., said catalyst comprising a refractory mineral oxide carrier, a halogen element present in combined form, and containing metals in a free or combined state on said carrier as follows:
- a. From 0.02 to 2% of at least one metal from the platinum group;
- b. From 0.02 to 2% of tin;
- and
- c. From 0.01 to 5% of at least one metal selected from the group consisting of scandium, yttrium, thorium, and uranium;
- said percentages, determined relative to the respective elemental form, being based upon the total catalyst weight.
