Heating value of syngas

WebSyngas, or synthesis gas, is a combustible gas mixture of carbon monoxide, carbon dioxide, trace gasses and hydrogen. It is produced through thermochemical conversion from … The chemical composition of syngas varies based on the raw materials and the processes. Syngas produced by coal gasification generally is a mixture of 30 to 60% carbon monoxide, 25 to 30% hydrogen, 5 to 15% carbon dioxide, and 0 to 5% methane. It also contains lesser amount of other gases. Syngas has less than half the energy density of natural gas. The first reaction, between incandescent coke and steam, is strongly endothermic, producing ca…
