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.
The syngas exiting the various syngas production processes primarily contains a mixture of hydrogen, carbon monoxide, carbon dioxide, along with unreacted methane and other trace components. The H2/CO ratio in the syngas is typically adjusted to meet the requirements of the downstream processes. These downstream processes include a wide range of gaseous, liquid or solid products, including:
- Industrial gases, such as pure H2 or CO
- Liquids, such as alcohols or transportation fuels
- Synthetic Natural Gas (SNG)
- Chemicals, such as Ammonia, acetic acid, and urea
Since each downstream process requires a specific syngas composition as well as limits to other contaminants, the syngas is typically conditioned by the following processes
