3624. ----- [STEINKOHLEN-BERGWERK “RHEINPREUSSEN”].  (Koppers Co.). Hydrocarbons From Hydrogen and Carbon Monoxide.  United States Patent 2,220,357, Nov. 24, 1936, Serial No. 112,549; in Germany Nov. 26, 1935; 4 claims (Cl. 190-449).  Chem. Abs., vol. 35, 1941, p. 1980.

Describes arrangement of apparatus and a process for making liquid hydrocarbons by catalytically treating 2 H₂ and 1 CO by means of a known catalyst capable of forming liquid hydrocarbons from 2 H₂ and 1 CO, which comprises.  Making alternate blows of air and runs of water gas making steam through a generator fuel bed of carbonaceous fuel to produce original water gas containing H₂ and CO in ratio 2:1 during the blows, storing the heat of the spent blow gases in a conversion chamber separated from the generator fuel bed; during the runs, purifying the original 2:1 gas and then catalytically treating it in the presence of a catalyst known to be capable of reacting 2 H₂ and 1 CO to liquefiable hydrocarbons in a primary catalytic reaction chamber to form the liquid hydrocarbons from the 2:1 ratio of H₂ to CO, removing the liquid and solid products from the reaction gas left over from the primary catalytic reaction, and then flowing the residual leftover reaction gas together with the steam by themselves through the aforesaid conversion chamber and converting the gaseous hydrocarbons in the leftover-gas reaction gas to H₂ and CO in ratio 2:1 by the heat stored in the conversion chamber from the blow gasse of the previous blow of the generator fuel bed, thereafter catalytically treating the so converted 2 H₂:1 CO in the leftover reaction gas in the presence of a catalyst as aforesaid in a secondary catalytic reaction chamber separate from the primary catalytic reaction chamber to form further liquid hydrocarbons from the leftover gas and recovering the further liquid hydrocarbons from the reaction gases of the secondary catalytic reaction chamber.
