What does synthesis gas (water gas) consist of?
oxygen (O2) and hydrogen (H2)
methane (CH4) and water (H2O)
carbon dioxide (CO2) and hydrogen (H2)
carbon monoxide (CO) and hydrogen (H2)
Water gas is a mixture of carbon monoxide and hydrogen produced from synthesis gas. Synthesis gas is a useful product, but requires careful handling due to its flammability and the risk of carbon monoxide poisoning. The water-gas shift reaction can be used to reduce the carbon monoxide while producing additional hydrogen, resulting in water gas.
