It has been well documented that the CuO/ZnO/ZrO2 catalyst shows high activity in the methanol synthesis from CO2 and H2. The CuO/ZnO/ZrO2 based catalysts were obtained by decomposing the citrate complexes, by adding small amount of promoters – Ce, Cr, Ga, La, Pd in order to improve the new catalyst’s catalytic properties. The catalytic activity was measured using a tubular high-pressure fixed bed reactor. The promoters were found to improve the catalytic activity and stability in the reaction of methanol synthesis from carbon dioxide and hydrogen. The positive influence of promoters, especially Ga, La, Ce and Cr on the activity and selectivity of the developed catalysts in the investigated process has been demonstrated. Keywords: methanol synthesis, Cu/ZnO/ZrO2 catalyst, Ce, Cr, Ga, La, Pd promoters.
