文摘
- •
Kinetics of two catalysts for methanol synthesis from CO2/H2 were assessed.
- •
Power-law models describe both methanol synthesis and reverse water gas shift reaction.
- •
Cu/ZnO/ZrO2 catalyst has better low temperature methanol selectivity than Cu/ZnO/Al2O3 catalyst.
- •
Overstoichiometric H2 in the feed strongly enhances methanol selectivity.
- •
8-parameter models accurately fit the data with an average error below 10%.
