There are various processes used for the production of syngas. Syngas can be produced from any hydrocarbon or organic material. Some examples of feedstocks used to produce syngas include natural gas, liquid petroleum gas (LPG), naphtha, coal, biomass, wood, and refuse. The selected production process is typically based on a number of the following factors: types of available, cost of feedstocks, and the desired syngas product composition. The syngas composition is commonly referred to in terms of H2/CO ratio, which is simply the moles of hydrogen divided by the moles of carbon monoxide.
