Modifications in the Composition of CuO/ZnO/Al2O3 Catalyst for the Synthesis of Methanol by CO2 Hydrogenation

Renewable methanol, obtained from CO2 and hydrogen provided renewable energy, was proposed to close the loop. In industry, methanol synthesis using catalyst CuO/ZnO/Al2O3 occurs at a high pressure. We intend make certain modification on traditional work lower pressure, maintaining selectivity. Therefore, three heterogeneous catalysts were synthesized by coprecipitation improve activity selectivity under mild conditions of temperature Certain modifications Cu/Zn/Al2O3 employed such as time addition Pd dopant agent. The most efficient among those tested palladium-doped catalyst, 5% Pd/Cu/Zn/Al2O3. This had 64% 210 °C 5 bar.
