Do iron ions have an effect on the catalysts used for hydrogen production via methanol cracking? Toxic substances such as sulfur, phosphorus, and halogen elements can poison the catalysts used in the hydrogen production via methanol cracking. I wonder whether iron ions have any effect on these catalysts as well I would appreciate your advice! ! !
In the methanol-to-hydrogen process, iron ions mainly come from rust. High levels of iron ions can lead to the formation of some high-carbon hydrocarbons. The most representative example is the formation of paraffin; white paraffin solids can be found in the cooling chamber. Currently, most methanol-to-hydrogen plants use the SCST-401-53 methanol-to-hydrogen catalyst, which contains additives that effectively suppress the formation of higher carbon hydrocarbons.
