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.
Claims5
A process of producing coal briquettes to be gasified or devolatilized in a fixed fuel bed which comprises adding 10 to 30 percent by weight of ash to coal and forming a mixture therefrom, said mixture having a particle size below 0.2 mm, said coal containing water not in excess of 20 percent by weight, briquetting said mixture at a temperature in the range of 20.degree. to 100.degree. C. by applying a pressure of at least 750 kg/cm.sup.2.
