Gasification of fuels. [Use of less O and steam to produce more synthetic gases and a solid residue that can be used as fuel; high volatile bituminous coal produced gas of: CO 46. 1, H 44. 0, CO/sub 2/ 8. 6, CH/sub 4/ 0. 6, N 0. 5, and H/sub 2/S 0. 2%]
Regenerative method of underground gasification process of coal. [Heating value of 900-1000 Kcal/m/sup 3/ increased to 1300-1400 Kcal/m/sup 3/ by increasing O content to 23%; with O and steam it was 2500 Kcal/m/sup 3/; gas composition of CO/sub 2/ 13. 58, O 0. 22, CO 6. 32, H 58. 5, CH/sub 4/ 4. 28, N 17. 1%]
