      922.  HAGY, J. D. (Stanolind Oil & Gas Co.).  Gas Processing for the Synthesis of Hydrocarbons.  United States Patent 2,493,454.  Jan. 3, 1950; appl. Filed Dec. 15, 1944, Serial No. 568,315; 2 claims (Cl. 260-449.6).  Chem. Abs., vol. 44. 1950, p. 2221.

Compressed air, natural gas, and a small amount of recycled gas are raised to reaction temperature by combustion of a part of the gas with all of the air within a combustion case.  The remaining gas is bled into the hot gases from the combustion case at the entrance to the reformers.  The reaction within the reforming case is very nearly adiabatic.  The synthol feed gas so produced is supplied to the reactor using fluidized catalyst.  Bayonet type tube assembly removes heat directly from the reactor.  Saturated steam at 200 p.s. i. is generated within the tube assembly.  Control of the rate of heat removal may be either by variation of steam pressure or by control of the number of tubes in operation.  The product is cooled by direct contact with H2O.  Product is recovered from the uncondensed gases by adsorption on activated C.  Ordinarily 2 gas re-formers, 6 synthol reactors, and 2 product cooling towers of the types described may be used in a plant producing 5,000 bbl. Liquid product per day from 76,400 M. cu. ft. per D of natural gas.  16 United States patents cited.
