PURPOSE:To obtain a gas with a high hydrogen content at relatively low temp., by mixing a flammable material with a particular metallic oxide and gasifying the mixture. CONSTITUTION:0.1-10pts.wt. metallic oxide such as nickel oxides (e.g., Ni2O3) or iron oxides is added to 1pt.wt. flammable material such as heavy oil, coal liquefaction slurry residue, or coal, and the mixture is gasified in the presence (or absence) of oxygen or steam by heating up to 300-1,000 deg.C at a heating rate of 1-20 deg.C/min or heating in two steps; heating to 300-700 deg.C in the first step and heating to 800-1,000 deg.C in the second step. EFFECT:It is possible to prevent formation of tar, or dissolution or coagulation of char, and to obviate coking troubles. |
