Gas composition of methanol synthesis catalyst (CuO CATALYST)
Gas composition
Composition of raw gas: The raw gas used in methanol synthesis mainly consists of hydrogen, carbon monoxide and carbon dioxide. In addition, it may also contain a small amount of inert gases such as nitrogen and methane. The molar ratio of hydrogen to carbon monoxide in the raw gas is generally controlled within 2.0 - 2.5, and the molar ratio of hydrogen to (carbon monoxide + carbon dioxide) is approximately 2.1 - 2.2.
Impurity influence: Impurities in the raw gas can have a significant impact on the performance of the catalyst. For example, impurities such as sulfur and chlorine will react chemically with the active components of the catalyst, causing the catalyst to be poisoned and deactivated; oxygen will oxidize the active components in the catalyst, reducing its activity; excessive water vapor content may cause the active components of the catalyst to hydrolyze, damaging the structure of the catalyst. Therefore, the raw gas needs to undergo strict purification treatment before entering the synthesis reactor to remove the impurities.
