ABSTRACT:
Substantially ash-free carbonaceous reductant for use in reduction processes is made by recovering carbon from unused carbon monoxide. The carbon monoxide contacts a catalyst which promotes formation of carbon on the catalyst. Since the off-gases from many metal ore reduction processes employing coke include a significant quantity of carbon monoxide, this carbon monoxide may be recovered and used to form the reductant which is fed to the reduction process to replace a part of the coke consumed. Provided most of the carbon monoxide in the off-gases is utilized, very favorable cost savings are achieved when the ash-free reductant is used in place of the coke. Moreover, in some instances, the ore being reduced may be used as the catalyst. Since this ore-catalyst is at least partially reduced during manufacture of the reductant, a benefit is obtained.
