The physico-chemical properties of the Ni/Al2O3 catalysts with different amounts of Mo were characterized by physical techniques and were correlated with their catalytic performance. Experimental results showed that bimetal (Mo and Ni) based catalysts displayed superior catalytic performance than mono-metal (Ni) based catalysts. Addition of Mo to Ni catalysts could inhibit the formation of NiAl2O4 crystallites and facilitate the formation of active precursor NiMoO4, contributing to the formation of more active sites during the presulfidation process. The micro-morphology of active species was restructured and the needle-stacks of Ni-Mo-S were observed on the Mo improved catalysts. These structures and properties had important influence on the thioetherification. By optimizing the Mo/Ni atomic ratio, the catalysts with a Mo/Ni atomic ratio of 0.3 had suitable micro-morphologies and properties, exhibiting the best catalytic performance and selectivity for thioetherification. ¹Ø¼ü´Ê ×÷Õ߹ؼü´Ê:Thioetherification; FCC gasoline; Mo improved Ni/Al2O3 catalysts; Active structure; Ni-Mo-S phase KeyWords Plus:X-RAY PHOTOELECTRON; HYDRODESULFURIZATION ACTIVITY; NI-MO/GAMMA-AL2O3 CATALYSTS; NI/GAMMA-AL2O3 CATALYSTS; ALUMINA CATALYSTS; NI; HYDROGENATION; CO2; SPECTROSCOPY; TEMPERATURE ×÷ÕßÐÅÏ¢ ͨѶ×÷ÕßµØÖ·: Ke, M (ͨѶ×÷Õß) ÏÔʾ¸ü¶à Univ Petr, Coll Sci, State Key Lab Heavy Oil Proc, Beijing 102249, Peoples R China. ͨѶ×÷ÕßµØÖ·: Song, H (ͨѶ×÷Õß) ÏÔʾ¸ü¶à Univ Calgary, Dept Chem & Petr Engn, Calgary, AB T2N 1N4, Canada. µØÖ·: ÏÔʾ¸ü¶à [ 1 ] Xian Shiyou Univ, Sch Chem & Chem Engn, Xian 710065, Shaanxi, Peoples R China ÏÔʾ¸ü¶à [ 2 ] Univ Petr, Coll Sci, State Key Lab Heavy Oil Proc, Beijing 102249, Peoples R China ÏÔʾ¸ü¶à [ 3 ] PetroChina Petrochem Res Inst, Beijing 102206, Peoples R China ÏÔʾ¸ü¶à [ 4 ] Univ Calgary, Dept Chem & Petr Engn, Calgary, AB T2N 1N4, Canada µç×ÓÓʼþµØÖ·:keming@cup.edu.cn; sonh@ucalgary.ca »ù½ð×ÊÖúÖÂл »ù½ð×ÊÖú»ú¹¹ ÊÚȨºÅ PetroChina Innovation Foundation, China 2107D-5007-0401 State Key Laboratory of Heavy Oil Processing, China University of Petroleum, China ²é¿´»ù½ð×ÊÖúÐÅÏ¢ ³ö°æÉÌ ELSEVIER SCI LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND ÆÚ¿¯ÐÅÏ¢ Impact Factor (Ó°ÏìÒò×Ó): Journal Citation Reports Àà±ð / ·ÖÀà Ñо¿·½Ïò:Energy & Fuels; Engineering Web of Science Àà±ð:Energy & Fuels; Engineering, Chemical ÎÄÏ×ÐÅÏ¢ ÓïÑÔ:English Èë²ØºÅ: WOS:000447799400049 ISSN: 0016-2361 eISSN: 1873-7153 ÆäËûÐÅÏ¢ IDS ºÅ: GX5OS Web of Science ºËÐĺϼ¯ÖÐµÄ "ÒýÓõIJο¼ÎÄÏ×": 53 Web of Science ºËÐĺϼ¯ÖÐµÄ "±»ÒýƵ´Î": 0 |
