摘要

本研究主要研究了两种相同制备的0.1 wt.%钯促进介孔氧化铝(MA)和SBA-15负载CO (15 wt.%)催化剂通过费托催化(FT)途径催化合成气(CO + H2)的转化。费托反应在固定床管式反应器中进行，温度220°C，压力30 bar, H2/CO比~2，气体每小时空速(GHSV)为500 h−1。采用不同的分析技术，如氮气吸附-解吸、氢气程序升温还原(H2-TPR)、NH3程序升温解吸(NH3- tpd)、x射线衍射(XRD)和透射电子显微镜(TEM)，对催化剂进行了详细的表征。结果表明，SBA-15负载型催化剂对C6-C12的选择性较高(57.5%)，MA负载型催化剂对C13-C20的选择性较高(46.7%)。该研究将这两种支撑材料的使用归因于通过FT合成生产液态烃。

Fischer–Tropsch synthesis over Pd promoted cobalt based mesoporous supported catalyst

The present study focuses on the catalytic conversion of syngas (CO + H2) through Fischer–Tropsch (FT) route using two identically prepared 0.1 wt.% palladium promoted Mesoporous Alumina (MA) and SBA–15 supported Co (15 wt.%) catalysts. The Fischer–Tropsch activity is performed in a fixed bed tubular reactor at temperature 220 °C and pressure 30 bar with H2/CO ratio ~2 having Gas Hourly Space Velocity (GHSV) of 500 h−1. Detail characterizations of the catalysts are carried out using different analytical techniques like N2 adsorption-desorption, Temperature-programmed reduction with hydrogen (H2-TPR), Temperature-programmed desorption with NH3 (NH3-TPD), X-Ray Diffraction (XRD), and Transmission Electron Microscopy (TEM). The results show that the SBA–15 supported catalyst exhibits higher C6–C12 selectivity (57.5%), and MA supported catalyst facilitates the formation of higher hydrocarbons (C13–C20) having a selectivity of 46.7%. This study attributes the use of both the support materials for the production of liquid hydrocarbons through FT synthesis.

期刊介绍： OGST - Revue d''IFP Energies nouvelles is a journal concerning all disciplines and fields relevant to exploration, production, refining, petrochemicals, and the use and economics of petroleum, natural gas, and other sources of energy, in particular alternative energies with in view of the energy transition. OGST - Revue d''IFP Energies nouvelles has an Editorial Committee made up of 15 leading European personalities from universities and from industry, and is indexed in the major international bibliographical databases. The journal publishes review articles, in English or in French, and topical issues, giving an overview of the contributions of complementary disciplines in tackling contemporary problems. Each article includes a detailed abstract in English. However, a French translation of the summaries can be provided to readers on request. Summaries of all papers published in the revue from 1974 can be consulted on this site. Over 1 000 papers that have been published since 1997 are freely available in full text form (as pdf files). Currently, over 10 000 downloads are recorded per month. Researchers in the above fields are invited to submit an article. Rigorous selection of the articles is ensured by a review process that involves IFPEN and external experts as well as the members of the editorial committee. It is preferable to submit the articles in English, either as independent papers or in association with one of the upcoming topical issues.
