391.     BRUNER, F. H.  Quality of Synthetic Gasoline From Natural Gas.  Ind. Eng. Chem., vol. 41, No. 11, 1949, pp. 2511-2515.

      Gasoline produced in this country by the fluidized iron-catalyzed hydrogenation of CO is of much higher quality than that produced commercially in Europe by the Fischer-Tropsch, fixed-bed, Co-catalyzed process.  In contrast to the high-boiling, paraffinic material produced over Co, the hydrocarbons produced by the American process are relatively low-boiling and highly olefinic.  The olefin characteristic permits the conversion of the gasoline to a high-octane fuel or blending stock by a simple catalytic treatment.  A 7-lb. Reid vapor pressure, 400° F. end-point naphtha has a C.F.R.M. clear octane of 82 and a C.F.R.R. octane of 92.  The synthetic fuel blends normally in straight-run and cracked products.
