2079.     LEE, J. A.  Esso’s Fluid Catalyst Modifies Fischer-Tropsch.  Chem. Eng., vol. 54, No. 10, 1947, pp. 105-107.

        This paper describes certain of the modifications that are being made in the Fischer-Tropsch process by the Standard Oil Development Co. in the pilot plants at Baton Rouge.  Natural gas is being processed to form liquid fuels and chemicals through use of the fluid catalyst.  Results thus far have demonstrated satisfactorily the use of the fluid catalyst technique.  It is found to be an excellent tool for securing uniform temperatures and high rates of heat transfer.  Conversion and yield have been good.  It is estimated that a synthesis plant to produce 8,300 bbl./day of gasoline having an A.S.T.M. unleaded octane no. of about 80 after mild treatment and 1,050 bbl./day of gas oil would cost about $35,000,000, exclusive of the equipment for recovery of oxygenated compounds.  The method appears reasonably attractive from an economic standpoint at present.
