Patent ID: 8906314

Claim:
A bubble column reactor comprising: a reactor body which contains a slurry having solid catalyst particles suspended in a liquid; an inflow port which is provided at the bottom of the reactor body and allows a synthesis gas including carbon monoxide gas and hydrogen gas as the main components to flow into the slurry therethrough; an outflow port which is provided at the top of the reactor body and allows gaseous hydrocarbons synthesized by a chemical reaction between the synthesis gas and the slurry, an unreacted synthesis gas, and the like to flow out therethrough; a demister which is disposed between the liquid surface of the slurry within the reactor body and the outflow port so as to capture the catalyst particles passing therethrough; a heat transfer tube which is disposed in the reactor body so as to contact the slurry; and a heating device configured to heat the demister, wherein the heating device includes a heating tube of which at least part is disposed within the demister and a vapor-liquid separator configured to supply a heating medium into the heating tube, wherein the vapor-liquid separator connects with the heat transfer tube and the heating tube, and is configured to separate coolant water flowing through the heat transfer tube into steam, by heat exchange between the slurry and the water, and a liquified water, to supply the separated steam into the heating tube as the heating medium, and to supply the separated liquified water into the heat transfer tube.
