    摘要: Green briquettes made from particulate carbonaceous material and lignosulfonate as a binder are cured in an oven in the presence of circulating gases containing a high percentage of oxygen and superheated steam. The sulfur derived from the binder is oxidized and then hydrolyzed (exothermic reactions) at the curing temperature with formation of sulfuric acid, which is dissociated (endothermic reaction) in the case of a temperature rise. The reactions provide a means for thermal balance within the curing oven.

    摘要: A combustible shaped body or fuel briquette is prepared by forming an essentially homogeneous mixture of a particulate fuel material such as coal dust and a curable binder such as lignosulphonate plus sodium dichromate; adding to the mixture an agent such as sulphuric acid which causes or accelerates curing, in situ; and shaping the resultant composition before the binder has cured, e.g. in a briquetting press. Briquettes are produced which can be sufficiently cured for stacking and packing, within 1 hour.
