2942.     ---------------.  [RUHRCHEMIE, A.-G.]  [Course of the Pressure Synthesis When Using an Initial Gas Rich in Carbon Monoxide.]  FIAT Reel K-20, no date, frames 11-17; PB 70,211; TOM Reel 287.

        Gas used consisted of CO:H₂=1:1.  Higher yields of liquid products were obtained than with normal synthesis gas.  In order to obtain a good conversion of the CO, temperatures up to 215° were used.  The total product consisted of about equal parts of gasoline, middle oil, and paraffin, the latter being about 8% less than in normal synthesis.  The olefin content of the gasoline was 32-36 vol. % and that of the middle oil 24-27%.  With a catalyst containing Co, 100:ThO₂, 15; kieselguhr, 600; and a gas rich in CO, considerably better results were obtained.  The conversion of CO was 92% and the ratio of liquefaction 89%.  The content of paraffin was 17% higher than with the normal catalyst.
