| 摘要 |
Hydrocarbon fractions boiling between 180 DEG and 600 DEG F. and containing aromatics, olefins, and sulfur and nitrogen compounds are hydrogenated with a platinum-palladium catalyst to reduce the concentration of aromatics and olefins. The catalyst is prepared by saturating a porous inert carrier, preferably alumina, with an aqueous acid solution of chloroplatinic acid and palladium (ous) chloride in a specified mole ratio of platinum to palladium. The saturated carrier is subsequently dried, calcined and reduced.
