Can methanol synthesis catalysts be reduced using methanol?
Thread Content
Can methanol be used as a reducing agent for methanol synthesis? A newly built methanol plant is seeking advice on whether a methanol temperature-raising reduction catalyst can be used, due to issues with the methanol circulation pump and water-gas production
No, these are two different catalysts
Without hydrogen, methanol is used directly to produce hydrogen.
Methanol is hydrolyzed to produce hydrogen and carbon dioxide under the action of copper-based catalysts. Due to the lack of reduction of the catalyst, its activity is low. As methanol is gradually hydrolyzed to produce hydrogen, the catalyst is also gradually reduced, its activity increases, and the reduction process accelerates.
Methanol, under copper-based catalysis, is primarily used to produce formaldehyde. It is only when the temperature is high that hydrogen and carbon dioxide are present ； The concentration of hydrogen gas produced by the reaction cannot be guaranteed in the gas.
When the methanol catalyst of a certain company was heated, methanol entered the system, causing the catalyst to be reduced. Although it’s not ideal, methanol is still produced.
