Passivation of metals on FCC (fluid catalytic cracking) catalysts with antimony
A ten-month comparison of results obtained in a Phillips heavy oil cracker before and after passivation of the catalyst with antimony showed an increase of the fresh oil feed rate by 11.9Vertical Bar3<, an oil conversion increase of 5.4Vertical Bar3<, a gasoline production increase of 20.4Vertical Bar3<, and decreases of coke and hydrogen production of 9.1 and 61.2Vertical Bar3<, respectively. In a test on a commercial FCC unit limited by gas compressor capacity, metals passivation permitted an increase in the riser temperature, which gave a higher Research octane number gasoline, without overcracking. The antimony apparently forms an alloy with nickel which is surface-enriched antimony. Earlier laboratory studies performed for the development of the antimony additive are reviewed.
