        Construction of the coal-to-oil gasoline-synthesis plant recently announced by the South African Coal, Oil & Gas Corp. Ltd., will be started soon by the M. W. Kellogg Co. The plant will be adjacent to the Vaal River, near Coalbrook in the Orange Free State, about 40 miles south of Johannesburg.  The project is an integrated plant, which embraces the opening of virgin coal deposits, construction of aboveground gasification facilities to transform coal to synthesis gas, and the complete synthesis plant to produce liquid hydrocarbons.  Kellogg’s Synthol process will be utilized.  It has been thoroughly developed and tested in the company pilot plant.  The Coalbrook coal to be used as the raw material occurs at an average depth of 400 ft., with seams ranging in thickness from 10-20 ft.  it is mined at a pithead cost equivalent to less than $1.00 per ton.  Operations will be adjusted to produce maximum gasoline and diesel oil rather than chemicals.
