                Carbonization and gasification processes for brown coal are reviewed briefly.  At Dessau a mixture of low-temperature brown-coal gas is mixed with coal gas.  Successful experiments were made with brown coal in the Bube and Heinze gas producers at the Halle and Dresden gas works.  Zittau has contracted for gas to be made from brown coal in the Lurgi high-pressure gas generators, with a mixture of O2 and H2O vapor.  Several other processes have been or are now being operated on a semi-plant scale.
