Pd-promoted Cr/ZnO catalyst for synthesis of methanol from syngas Original Research Article

The effect of palladium on the performance of Cr/ZnO catalyst was investigated for the synthesis of methanol from synthesis gas. Hydrogen adsorption on the Pd-Cr/ZnO well fits the equation combination of Langmuir isotherm equation and Freundilich isotherm equation while CO adsorption well fits Freundilich model. Addition of palladium in Cr/ZnO promoted the activity and selectivity of methanol synthesis.
