The addition of hydrogen to the coal substance to modify its structure fand convert it Into all wat the basle principle of the Bergius or hydrogen tion process. An alternative method of treating the coal was to break -down into constituent ele ments, carbon and hydrogen, This synthesis was the basis of the Fischer Tropseh process.
In the Bergius process the hydro= fen was made to react with the coal tata temperature of 450 to 500 doe Brees C and a pressure of 200 to 280 Atmospheres. tue conversion of coal
stages, nto gasoline being effected in three Five Tons to One For the production of one ton of gasoline Ik was necessity to. process About 145 tons of coal. In addition {othe coat used in the process, about tons of coal per ton of Rasoline produced were required for the pro-Suction of hydrogen, steam, power, cle. There were flits required ap= proximately five tons of coal for each fon of gasoline produced, The Fischer Tropsch process differ= ed fundamentally from the hydroperation process in two Fospeets. firstly the coal, was broken down into its simplest constituents by converting into a mixture of hydrogen and carbon monoxide and secondly the Another process, known as the Pott Broche process, for the product all from i 100 degrees the temperature he coal decomposed into coke, Killer Not Found Shanghai, Dee, 18, Conditions in the North of the Soo chow Creek Giseil, following the attack made 1 yesterday, although Japanese sentries on various Soochow and Tongkew Crock bridges still maintained strict searches of Chinese centering the area The Killer of the Japanese ameer was till at large yesterday, having escaped into a.
