ABSTRACT:
A method of selectively hydrodenitrogenating various raw hydrocarbon oils such as various petroleum feedstocks, coal liquids, shale oils and sand oils, which method comprises passing the raw hydrocarbon oil along with hydrogen (H.sub.2) over sulfided carbon supported Fe--Mo catalysts, whereby the raw hydrocarbon oil is hydrodenitrogenated with a selectivity significantly higher than that is possible with conventional alumina supported hydrotreating catalysts.
