The behavior of sulfur in the cracking of residual oils with generation of hydrogen has been investigated. In the cracker, most of the sulfur contained in the feed oil is transferred to a 560°C+cracked oil fraction and coke. No metal sulfide has been detected by sulfur print analysis in the catalyst after the cracking reaction. In the regenerator, the sulfur in the coke deposited on the catalyst has been burned with air to produce gaseous sulfur compounds, which react with ferrous oxide, and the sulfur is fixed in the catalyst as iron sulfide. The sulfur content in the gas from the regenerator is approximately 200ppm that corresponds to 0.35% of the sulfur fed to the regenerator, while the percent of gasification of carbon is 58. In the hydrogen generator, the iron sulfide is partially desulfurized by steam.
