A new technical Process of coking and gasification of powder coal by rapid heating together with its theoretical basis are illustrated. The products of pyrolysis of the powder coal by rapid heating are compared with those of ordinary slow heating. The differences of the products in quality are explained with the structure of coal and the mechanism of pyrolysis. Coke breeze Produced by rapid heating of powder coal with its microstrusture of high porosity exhibits a higher reactivity which gives much influence upon the effect of gasification of the breeze. Kinds of coal suitable, for the new process and the elevation of its economical value are also treated.
