Abstract:
1. A process for converting a liquid hydrocarbon feedstock into lower molecular weight hydrocarbon compounds in a slurry bed reactor, the process comprising: a. mixing the liquid hydrocarbon feedstock and an excess of hydrogen gas in a mixing zone under predetermined conditions of temperature and hydrogen partial pressure to dissolve a portion of the hydrogen gas in the liquid hydrocarbon feedstock to produce a mixture of hydrogen-enriched liquid hydrocarbon feedstock and undissolved hydrogen gas; b. introducing the mixture produced in step (a) into a flashing zone under predetermined conditions to separate undissolved hydrogen gas and light hydrocarbon components and recovering a hydrogen-enriched liquid hydrocarbon feedstock; c. introducing the hydrogen-enriched liquid hydrocarbon feedstock into a reaction zone containing at least one slurry bed reactor with at least one catalyst or catalyst precursor and reacting the feedstock to convert at least a portion of the feedstock into lower boiling point hydrocarbons; d. recovering a reactor effluent from the at least one slurry bed reactor comprising converted hydrocarbon products and unconverted liquid feedstock; e. introducing the reactor effluent from the at least one slurry bed reactor into a separation zone to separate converted hydrocarbon products from unconverted liquid feedstock; f. recovering the converted hydrocarbon products from the separation zone; and g. recovering the unconverted liquid feedstock from the separation zone.
