Show Refining Gasoline From Oil Shale Process Told Two chemical engineers with the US U.S. Bureau Dureau o of Mines reported progress in efforts to find ways to economically produce produce produce pro pro- duce good quality gasoline from crude shale oil all THE REPORT was made by Lawrence K Barker Darker and P. P J J. J Cottingham o of the Bureaus Bureau's Laramie Wyoming Energy Research Center at the the- national meeting o of the American Chemical So So- clety Shale oil found in tightly packed clay mud and been a source of gasoline gasoline gaso line for about 20 years as as a substitute for forthe forthe forthe the worlds world's diminishing ng supply o of natural oil wl which ch is refined into gasoline HOWEVER CONSIDERABLE expensive sive sine processing is required to turn shale oil all into gasoline and it has not been economically competitive with gasoline refined from rom natural oil all Barker Darker and Cottingham reported that thata a process in which shale oil is treated twice with hydrogen has been developed develop develop- ed which considerably reduces the cost costo o of converting it into gasoline |
