In the method developed in the USSR for production of molded coke, the rapid heating of the coal charge is conducted by a gaseous heat carrier passing through all the stages of the system. The excess gas contains combustion products of the coke oven gas, water vapor, coal dusts, and products of the thermal decomposition of the coal. Investigations were conducted on the catalytic purification of this gaseous heat carrier. The performance efficiency of catalysts and mixtures of two catalysts was determined. The catalysts acted also as granular bed filters to remove the coal dusts; however, the dust accumulation had to be removed periodically to regenerate the catalysts. The method removes phenol, hydrogen cyanide, carbon monoxide, ammonia, and hydrocarbons. The use of a bag filter for removal of dusts before purification of the carrier gas is recommended. 5 references, 2 tables.
