Hydrotreating-hydrocracking process for manufacturing gasoline range hydrocarbons
Abstract
Abstract A process for converting sulfur and nitrogen containing hydrocarbons boiling in the 400*-1,000* F. range into gasoline range hydrocarbons boiling below about 400* F. which comprises hydrotreating the sulfur and nitrogen containing hydrocarbons to yield a liquid hydrocarbon product containing less than 1 ppm nitrogen, and hydrocracking such hydrotreated hydrocarbon to yield gasoline boiling range product. The hydrotreating reaction is improved by employing pressures in the range of from about 1,200-1,500 psig and hydrogen to hydrocarbon ratios in the range of 10,000-20,000 SCF/B. By operating the hydrocracking reaction at a higher pressure than the hydrotreating reaction only one hydrogen circulation system is required wherein a hydrogen recycle gas is from the hydrocracking reaction effluent is charged to the hydrotreating reaction, wherein a gas stream comprising hydrogen, hydrogen sulfide and ammonia separated from the hydrotreating reaction effluent is treated to remove hydrogen sulfide and ammonia, wherein such treated gas is mixed with makeup hydrogen, compressed and recycled to the hydrocracking reaction.
