Ryan, R C

Hydroconversion catalysts containing Group VIII and/or Group VIB catalytically active metals on a support, and particularly those containing nickel and molybdenum on alumina, are improved in hydrodenitrification (HDN) activity by impregnation of additional molybdenum and/or tungsten carbonyls onto the catalyst by sublimation. Preferably from about 1 to 5% w molybdenum is added. The carbonyl impregnated catalyst is then dried, calcined and, generally sulfided before use in a hydrocarbon conversion process.
