Hydrocracking process for production of LPG and distillate hydrocarbons |
摘要 |
A catalytic hydrocracking process which provides for the simultaneous production of LPG and distillate hydrocarbons. The feedstock is introduced into a denitrification and desulfurization zone and then passed directly to a hot, high pressure stripper utilizing a hot, hydrogen-rich stripping gas to produce a first liquid stream boiling in the range of the feedstock and a first vapor stream comprising hydrocarbonaceous compounds boiling at a temperature below the boiling range of the feedstock. The first liquid stream is hydrocracked in a first hydrocracking zone and then passed to the denitrification and desulfurization zone. At least a portion of the first vapor stream is condensed to produce a second liquid stream comprising hydrocarbonaceous compounds boiling at a temperature below the boiling range of the feedstock. At least a portion of the second liquid stream is hydrocracked in a second hydrocracking zone containing a second hydrocracking catalyst to produce LPG boiling range hydrocarbonaceous compounds.
