        Large-scale experimental plant is described.  The generator consists of a cylindrical shaft with an effective cross-sectional area of 10.4 sq. ft. operating with a fuel bed 10 ft. deep.  With lignite, a daily output of 700,000 cu. ft. of gas was obtained.  With a mixture of steam and O₂ under 20-30 atm. pressure, a gas comparable, after simple purification, with normal town’s gas was obtained.  It is possible to obtain by this process of high output of gas from a small plant.  The successful operation of the high-pressure gasification process is shown to depend on the obtaining of the correct balance between the rate of production of CH₄ and the rate of gasification of coke in steam.
