Abstract:
1. A method for producing synthetic hydrocarbons, the method comprising: inserting a first tube into the top of a marine riser suspended in a body of water, wherein a Fischer Tropsch catalyst is comprised inside the tube, and wherein the tube is comprised in a second tube in the marine riser; injecting hydrogen and carbon monoxide into the top of the first tube; contacting the hydrogen and carbon monoxide with the Fischer-Tropsch catalyst at conditions sufficient to produce a mixture comprising synthetic hydrocarbons; forcing the produced mixture comprising synthetic hydrocarbons out of the bottom of the first tube and into the annulus of the marine riser; and producing the mixture comprising the synthetic hydrocarbons from the marine riser annulus, wherein heat generated from the Fischer-Tropsch reaction is rejected into the body of water as the mixture is produced.
