Since the catalytic dissociative reaction of the aliphatic group was initiated by the adsorption of the residue on the alumina support of the desulfurization catalyst, olefins produced by acid sites on the alumina are probably responsible for the catalyst deactivation through the deposition of coke. Use of an amorphous silica-alumina with stronger acid sites than alumina as the catalyst support for the desulfurization catalyst reduced the reaction temperature necessary for the desired conversion (WAT) by 20ｰC compared to the alumina support catalyst at 1500 h after the beginning of the reaction. However, catalyst deactivation of the catalyst supported on silica-alumina was significantly faster than of the catalyst supported on alumina. Feeding a mixture of Residue A (60 vol%) and Residue B (40 vol%) into the desulfurization process decreased catalyst deactivation of the combination of conventional catalysts supported on alumina. Although sulfur compounds in Residue B are important to reduce coke formation during the hydrotreatment of atmospheric residue,effective hydrotreatment of Residue A with long aliphatic chains was not achieved with the present catalyst com bination.","subitem_description_language":"en","subitem_description_type":"Other"},{"subitem_description":"高脂肪族・低硫黄常圧残さ油（残さ渦A）をアルミナに担持した脱硫触媒を用いて水素化改質を行うと，触媒の活性劣化速度が低脂肪族・高硫黄残さ油（残さ油
