Shayegh Department of Chemistry,Sharif University of Technology Journal Article 2011 01 03 The eect of operation variables, such as the H2/CO molar feed ratio, gas hourly space velocity (GHSV), temperature, and pressure, on the catalytic performance of the Co/Mn/TiO2 catalyst prepared at the Research Institute of the Petroleum Industry (RIPI) was investigated, and optimum reactor conditions were obtained to produce the maximum amount of light olens. The catalyst was prepared by co-precipitation of Co and Mn phases in the presence of commercial TiO2 with maximum selectivity for ethylene and propylene production. It was found that the [H2]/[CO]=2/1, space velocity (GHSV) of 1800 h????1, 280C temperature and 4 bar pressure were optimum operating conditions for the modied catalyst for the conversion of Synthesis Gas(SG) to light olens. The results were interpreted in terms of the structure of the catalyst. Characterizations of catalysts were carried out using XRD, SEM and BET specic surface area. https://scientiairanica.sharif.edu/article_3379_431f32d512e5a75bb8d47dd92522fc94.pdf
