Abstract:
An apparatus suitable for the conversion of synthesis gas to liquid hydrocarbon products, which comprises a plurality of injector-mixing nozzles, a tank reactor, a gas recycle line having a first end and a second end and a slurry recycle line having a first end and a second end wherein:a) the plurality of injector-mixing nozzles are arranged at or near the top of the tank reactor; b) each injector mixing nozzle has a first inlet for a suspension of a catalyst in a liquid medium, at least one second inlet for synthesis gas and an outlet which is positioned within the tank reactor for discharging a mixture of synthesis gas and the suspension from the injector-mixing nozzles in a downwards direction into the tank reactor, c) the tank reactor has a first outlet for discharging a product suspension at or near the bottom thereof and a second outlet for a gaseous recycle stream at or near the top thereof; d) the first end of the slurry recycle line is in communication with the first outlet of the tank reactor and the second end of the slurry recycle loop is in communication with the first inlet of the injector-mixing nozzles; and e) the first end of the gas recycle line is in communication with the second outlet of the tank reactor and the second end of the gas recycle line is in communication with the second inlet(s) of the injector-mixing nozzles.
