        Rice and Barley anthracites were gasified in the Wellman-Galusha producers used for the manufacture of synthesis gas from coke by O₂ gasification at Trail, B. C.  Both sizes were satisfactorily gasified using O₂ and steam and at gasification rates considerably above 100% increase in capacity over that obtained with air and steam.  The gas produced from the Rice anthracite was close to the composition desired for synthesis gas; that from the Barley size was not so good.  The coal consumption per 1,000 cu. ft. of raw gas was, respectively, 23.2 and 25.9 lb.  The O₂ consumption per lb. of fuel gasified was appreciably lower for Rice coal and slightly lower for Barley coal than for large coke.  Steam consumption per 1,000 cu. ft. of raw gas and per lb. of fuel gasified was higher for both Rice and Barley coal than for coke.  Operating results are tabulated, a heat balance is shown, and a flowsheet is given.
