摘要： A gasification process may include (a) introducing a liquid hydrocarbon feedstock and at least one of a dry feedstock or a first slurried feedstock into a reactor lower section, wherein the at least one dry feedstock or first slurried feedstock is introduced through two primary feed nozzles while the liquid hydrocarbon feedstock is introduced through at least two secondary feed nozzles; (b) partially combusting the feedstocks in the reactor lower section with a gas stream comprising an oxygen-containing gas or steam to evolve heat and form products comprising hot synthesis gas; (c) passing said hot synthesis gas from step (b) upward into a reactor upper section; (d) and introducing a second slurried feedstock into said reactor upper section, whereby heat from said hot synthesis gas supports reaction of the second slurried feedstock by pyrolysis and gasification reactions.

摘要： A two-stage gasification reactor may include a reactor lower section and a reactor upper section. The reactor lower section may include (a) a lower reactor body, (b) two primary feed nozzles, configured to introduce at least one of a dry feedstock or a first slurried feedstock and located on opposing terminal ends of the lower reactor body, and (c) at least two secondary feed nozzles, configured to introduce a liquid hydrocarbon feedstock, located on the lower reactor body. The reactor upper section may include (a) an upper reactor body, (b) at least one upper feed nozzle, configured to introduce at least one of a dry feedstock or a first slurried feedstock, located on the upper reactor body, and (c) an outlet.
