Gas phase synthesis of dimethyl carbonate from CO2 and CH3OH over Cu-Ni/AC. A kinetic study
ABSTRACT : The catalytic activity for dimethyl carbonate formation from carbon dioxide and methanol over mono and bimetallic Cu:Ni supported on activated carbon is presented. Bimetallic catalysts exhibit higher catalytic activity than the monometallic samples, being Cu:Ni-2:1 (molar ratio) the best...

ABSTRACT : The catalytic activity for dimethyl carbonate formation from carbon dioxide and methanol over mono and bimetallic Cu:Ni supported on activated carbon is presented. Bimetallic catalysts exhibit higher catalytic activity than the monometallic samples, being Cu:Ni-2:1 (molar ratio) the best catalyst; X-Ray diffraction, transmission electron microscopy, and metal dispersion analysis provided insight into the improved activity. In situ FT-IR experiments were conducted to investigate the mechanism of formation of dimethyl carbonate from methanol and carbon dioxide over Cu-Ni:2-1. The kinetics of the direct synthesis of dimethyl carbonate in gas phase over Cu:Ni-2:1 supported on activated carbon catalyst was experimentally investigated at 12 bar and temperatures between 90 oC and 130 oC, varying the partial pressures of CO2 and methanol. Experimental kinetic data were consistent with a Langmuir–Hinshelwood model that included carbon dioxide and methanol adsorption on catalyst actives sites (Cu, Ni and Cu-Ni), and the reaction of adsorbed CO2 with methoxi species as the rate determining step. The estimated apparent activation energy was 94.2 kJ mol-1. |

Los catalizadores bimetálicos presentaron una mayor actividad catalítica que los monometálicos, siendo la muestra Cu:Ni-2:1 el mejor catalizador. La caracterización de los materiales mediante análisis de difracción de rayos X, microscopía electrónica de transmisión y dispersión metálica permitieron sugerir una explicación al porqué de su mejor desempeño. Se realizaron experimentos de FT-IR in situ para investigar el mecanismo de formación de carbonato de dimetilo a partir de metanol y dióxido de carbono sobre Cu-Ni:2-1. Se estudió la cinética de la síntesis directa de dimetil carbonato en fase gaseosa sobre Cu:Ni-2:1 soportado en carbón activado, a 12 bar y temperaturas entre 90 oC y 130 oC, como función de la presión parcial del dióxido de carbono y del metanol. Los datos experimentales fueron consistentes con un mecanismo Langmuir-Hinshelwood, el cual incluyó la adsorción de dióxido de carbono y metanol sobre los sitios activos del catalizador (Cu, Ni, y Cu-Ni), siendo la reacción del dióxido de carbono adsorbido con las especies metoxi como etapa limitante. La energía de activación aparente estimada de la reacción fue 94,2 kJ mol-1.COL000194112application/pdfengUniversidad de Antioquia, Facultad de IngenieríaCatálisis AmbientalMedellín, Colombiainfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_2df8fbb1https://purl.org/redcol/resource_type/ARTArtículo de investigaciónhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by-nc-sa/2.5/co/http://purl.org/coar/access_right/c_abf2https://creativecommons.org/licenses/by-nc-sa/4.0/Gas phase synthesis of dimethyl carbonate from CO2 and CH3OH over Cu-Ni/AC.
