A process for the production of a pollutant-free particulate carbon (i.e., a substantially ash-, sulfur- and nitrogen-free car- bon) from carbonaceous feedstocks (21). The basic process involves de- oxygenating one of the gas streams formed in a cyclic hy- dropynolysis (10) methane pyrolysis (34) process in order to improve conversion of the initial carbonaceous feedstock. De-oxy- genation is effected by catalytically converting carbon monoxide, carbon dioxide, and hydrogen contained in one of the, pyrolysis gas streams (44), preferably the latter, to a methanol co-product. There are thus produced two products whose use is known perse, viz.; a substantially pollutant-free particulate carbon black (53) and methanol (49). These products may be admixed in the form of a liquid slurry of carbon black in methanol. |
