Sustainable process for the production of methanol from CO2 and H2 using Cu/ZnO-based multicomponent catalyst

Technoeconomics and Sustainability of Renewable Methanol and Ammonia Productions Using Wind Power-based Hydrogen

“…The temperature rise must be minimized in order to operate at good equilibrium values. However selectivity for methanol is high with a value of 99.7% at 5 MPa and 523 K with a H 2 /CO 2 ratio of 2.82 [63]. The energy efficiency for the concentrated CO 2 and hydrogen based methanol is around 46%.…”

“…To improve their catalytic performance, the CuO/ZnO catalysts have been modified with various metals, such as chromium, zirconium, vanadium, cerium, titanium, and palladium [30][31][32][33]62]. The long-term stability of the catalysts may be improved by adding a small amount of silica to the catalysts at reaction conditions of 5 MPa, 523 K [63]. A high catalyst activity is related to a high copper surface area or small crystallite size combined with intimate contact with the zinc promoter.…”

Carbon Dioxide Recycling: Emerging Large‐Scale Technologies with Industrial Potential

“…The Japanese company Mitsui Chemicals Inc. also completed a pilot methanol plant (100 t a À1 ) in Osaka in 2009, [95] developed in collaboration with the Research Institute of Innovative Technology for the Earth (RITE), Kyoto (Japan) in the Project for Chemical CO 2 Fixation & Utilization (1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999); supported by the New Energy and Industrial Technology Development Organization, NEDO). [96,97] The process utilizes CO 2 emitted in the exhaust of an adjacent petrochemical factory. In the pilot plant H 2 was a waste by-product of coke furnaces and other sources.…”

Latest Advances in the Catalytic Hydrogenation of Carbon Dioxide to Methanol/Dimethylether

“…5.5), supporting a direct influence of the oxide phases on the functionality of promoted Cu catalysts. This hypothesis is supported by the conclusions of a comparative study on the effects of Ga 2 O 3 , Cr 2 O 3 , Al 2 O 3 and ZrO 2 carriers on the reactivity of the Cu-ZnO system, showing different effects depending on the nature of oxide promoter [77].…”

“…The highest methanol yield was obtained by the addition of Ga, while In implies a severe activity loss. Toyir et al reported that the addition of Ga 2 O 3 to the Cu-ZnO system enhances the methanol production, due to selectivity values two times higher than that of the corresponding Cu-ZnO system [77]. Finally, studying the influence of Ce addition on Cu/Ce x Zr (1-x) O 2 catalyst, Pokrovski and Bell observed a strong increase of the methanol selectivity [31], later confirmed by Arena et al, though a low surface exposure depresses the catalyst productivity [28][29][30][31].…”
