  • HIGH TEMPERATURE METHANOL STEAM REFORMING CATALYST
    Publication number: 20230398520
    Abstract: The present disclosure relates generally to a methanol reforming catalyst composition comprising a ZnO phase, present in the composition in an amount of 20-75 wt. %; a zinc-aluminum spinel phase, present in the composition in an amount of 20-60 wt. %; and a Cu dopant phase, present in the composition in an amount of 0.1-20 wt. %. In various embodiments, the methanol reforming catalyst can achieve stable high methanol conversion rates and high hydrogen production rates at high temperatures (>300° C.).
