摘要
The influence of the porosity of gamma-Al2O3 on the performance of CuO-ZnO-Al2O3 catalysts for methanol synthesis from H-2 + CO2 mixture was studied. Various types of gamma-Al2O3 with different surface areas (from 130 to 280 m(2)/g) and pore sizes (from 3 to 11 nm) were investigated. N-2 adsorption, XRD, TPR studies and grand canonical Monte Carlo simulation were utilized to determine the correlation between their physico-chemical properties and catalytic performance. It was shown that the crystallite size of CuO (determined by XRD) and BET surface area of supports are not the key factors for methanol productivity. The TPR profiles of catalysts demonstrated a direct relationship between CuO-ZnO interaction with their catalytic performance. Interestingly, samples with the uniform pore size of 5 nm exhibit a higher CuO-ZnO interaction and the highest methanol yield. In addition, at this pore size, simulation results showed that the ratio of H-2 and CO2 inside the gamma-Al2O3 pore was 1.5, which could be an appropriate feed ratio for high methanol productivity.
