Show 'Liquid Coal' Proposed as V. S. Oil Wanes PITTSBURGH. Dec. 10 Mv-Dr. Thomas E. Baker, president emeritus emer-itus of Carnegie Institute of Technology, Tech-nology, offered "liquid coal" today as a substitute for diminishing supplies sup-plies of petroleum and a stimulant for the mining industry. Asserting that the United States is studying liquefaction of coal because be-cause the "price of petroleum must rise." the founder of the institute's coal research laboratory ssid last night In a rsdio address: "The time will and must come when great quantities of coal will be used to propel motor vehicles Coal Is already furnishing what the Oermans call "ersats" (substitutes) for natural substances and chief of these is a substitute for petroleum." petro-leum." I He predicted that costs of manufacturing manu-facturing the derivatives soon would decline, opening a vast new market for coal producers. But Arno Fieidner, government expert, declared In a simultaneous address to the Coal Mining Institute Insti-tute of America, it would be advisable advis-able from a "conservation point of view" to delay the manufacture of gasoline from coal "as long as possible." pos-sible." Theehief of the technological Drench of the U. B- bureau of mines told the 000 coal operators that present pres-ent conversion methods were "ingenious "in-genious and "thermally-wasteful ways" of obtaining power. The cost of making motor fuel from coal In British and Oerman plants, he said, had been estimated' as three to four times greater thai of producing gasoline from petroleum. petro-leum. "About four tons of coal," Fieidner Fieid-ner continued, "are required for the manufacture of one ton of gasoline gaso-line by one method. The gasoline obtained contains only 40 per cent of the energy .of coai." Dr. Baker asserted that transportation trans-portation of gas or liquid coal byproducts by-products In pipe lines would not seriously or permanentlymffrt railroads. - In addition to fuel, he said, othar products would be mad and "this would mean furnishing railroads with mors commodities which they might transport at a higher rate than that which they charge for the use of their coal cars." |
