METHANOL--THE "NEW FUEL" FROM COAL

THE ALTERNATIVE POSSIBILITIES OF AN AUTO FUEL FROM COAL ARE CONSIDERED. FROM BOTH BTU AND POLLUTION POINTS OF VIEW, METHANE IS AN EXCELLENT FUEL BUT SIGNIFICANT PROBLEMS IN FUEL HANDLING AND CONSUMPTION ARE INVOLVED IN THE SUBSTITUTION OF A GASEOUS FUEL FOR A LIQUID FUEL. ALTHOUGH IT HAS NUMEROUS ADVANTAGES, HYDROGEN IS CONSIDERED A LONG-TERM SOLUTION AND IS DEPENDENT ON THE DEVELOPMENT OF NEW FUEL CONVERSION SYSTEMS SUCH AS FUEL CELLS. THE TECHNOLOGY FOR MAKING A HIGH QUALITY GASOLINE FROM COAL HAS BEEN DEMONSTRATED. R&D EFFORTS TO PRODUCE CRUDE OIL FROM COAL ARE BEING CARRIED OUT BY A NUMBER OF ORGANIZATIONS. FROM THE STANDPOINT OF BOTH ECONOMICS AND TECHNOLOGY, HOWEVER, METHANOL IS THE MOST DESIRABLE ALTERNATIVE. THE U.S. BUREAU OF MINES AND OTHER ORGANIZATIONS ARE CONDUCTING THOROUGH EVALUATORY STUDIES TO DETERMINE REALISTIC OPPORTUNITIES AND DIRECT R&D EFFORTS FOR OPTIMUM MANUFACTURE. A COMPARATIVE STUDY OF THE PROPERTIES OF METHANOL, INOOCTANE AND GASOLINE ARE TABULATED. METHANOL WOULD REQUIRE A VERY LARGE FUEL TANK BECAUSE OF ITS LOWER HEATING VALUE. HOWEVER, BECAUSE OF ITS HIGH LATENT HEAT OF VAPORIZATION, AND BECAUSE IT PRODUCES MORE MOLES OF COMBUSTION PRODUCT, IT PROVIDES MORE POWER THAN GASOLINE. EXTENSIVE TESTS OF METHANOL BOTH AS A REPLACEMENT FOR AND AS A BLEND WITH GASOLINE HAVE YIELDED PROMISING RESULTS. RESULTS OF EXTENSIVE EXHAUST EMISSION TESTS SHOWED THAT THE EMISSIONS OF THE TEST CAR FUELED ON METHANOL AND A SINGLE CATALYTIC MUFFLER WERE WELL BELOW THE 1975-76 FEDERAL STANDARDS. THE FACTORS CONTRIBUTING TO THE LOW EMISSION ARE REVIEWED. ALTHOUGH USE OF 100 PERCENT METHANOL WOULD HAVE THE POTENTIAL OF A MUCH LARGER CONSUMPTION AS A GASOLINE REPLACEMENT THAN THE BLENDED PRODUCT, THE LATTER HAS THE SIGNIFICANT ADVANTAGE OF NOT REQUIRING MAJOR CHANGES IN STORAGE AND DISTRIBUTION FACILITIES. METHANOL IS ALSO BEING CONSIDERED AS A FUEL FOR GENERATING ELECTRICITY. ALTERNATIVE COAL GASIFICATION PROCESS FOR MAKING METHANOL ARE CONSIDERED. A COAL-GASIFICATION TECHNOLOGY, TO PRODUCE BOTH METHANE AND METHANOL USING FLUID BED COAL, IS OUTLINED. THE ECONOMICS OF METHANOL PRODUCTION FROM COAL ARE DISCUSSED.
