Abstract

Sulfur and nitrogen species were removed from straight run gas oil (SRGO) through adsorption by activated carbon materials and treated oil was studied in conventional HDS reaction to evaluate the effects of pre-treatment on the HDS activity. Quinolines, indoles, and carbazoles were found in nitrogen-specific chromatogram of feed gas oil. Sulfur and nitrogen species removal depended on the types of carbon materials. MAXSORB-II, which has the largest surface area and oxygen content, showed the largest capacity for sulfur and nitrogen species. When 70% of nitrogen species was removed, attainable sulfur level was 11 ppm S while 180 ppm S for mother SRGO. Partial removal of nitrogen species from SRGO was very effective to achieve sulfur content < 10 ppm S using current catalyst and process conditions.
