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.).
Claims15
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, present in the composition in an amount of 0.1-20 wt. %.
A calcined methanol reforming catalyst composition comprising oxides of Zn, Al, and Cu, wherein:
- Zn is present in the composition in a total amount of 40-80 wt % (e.g., 60-80 wt. %), calculated as ZnO;
- Al is present in the composition in a total amount of 20-50 wt. % (e.g., 20-40 wt. %), calculated as Al2O3;
- and
- Cu is present in the composition in a total amount of 0.5-25 wt. % (e.g., 1-15 wt. %), calculated as CuO,
- wherein the catalyst composition comprises at least 20 wt. % (e.g., at least 30 wt. %, or at least 40 wt. %) zinc-aluminum spinel, as determined by XRD and calculated as ZnAl2O4.
