Abstract
Briquettes made of mainly coal are described to which there has been added 10 to 30% by weight of ash (other than ash which is contained in the coal normally). The briquettes formed from such a mixture have strength which permits them to be subjected to gasification or carbonization in a fixed bed. Also described is a method for forming the briquettes.
