Ch3oh+co
Carbon monoxide and hydrogen react over a catalyst to produce methanol. Today, the most widely used catalyst is a mixture of copper and zinc oxides, supported on alumina, as first used by ICI in 1966. At 5–10 MPa (50–100 atm) and 250 °C (482 °F), the reaction is characterized by high selectivity (>99.8%). The production of synthesis gas from methane produces three moles of hydrogen for every mole of carbon monoxide, whereas the synthesis co… WebCO + 2 H 2 → CH 3 OH. which is the same as listed above. In a process closely related to methanol production from synthesis gas, a feed of hydrogen and CO 2 can be used directly. The main advantage of this …
