A powder of coal, coke, anthracite, lignite or wood charcoal, or their mixt. is blended with an aq. soln. of Fe cpd. and then is directly compressed to form perforated briquettes or oval briquettes. Alternatively, the kneaded mixt. is dried and opt. supplied with a gas-absorbing compd. (e.q. soda cpd. bentonite, lime cpd., Mg cpd. or SiO2), an agent for fixing S and CO (e.q., MgO or calcined dolomite), and a binder (e.q. pitch or condrus ocellatus) and is then compressed into briquettes. The process fixes harmful and malodorous S-cpds. liberated by the combustion of the briquettes.
