分析了莱托尔(Litol)系统加氢反应机理,提出了"氢油反应当量比"的概念,指出了要维持莱托尔系统正常运行,必须保持足够的氢油反应当量比,当粗苯原料中甲苯、二甲苯等重组分含量增加时,要相应地增加氢/油摩尔比;实践证明其既能保证莱托尔系统加氢催化剂正常运行,又能保证装置运行的经济性,解决了莱托加氢装置加氢催化剂出现早期活性下降现象的问题.
分析瞭萊託爾(Litol)繫統加氫反應機理,提齣瞭"氫油反應噹量比"的概唸,指齣瞭要維持萊託爾繫統正常運行,必鬚保持足夠的氫油反應噹量比,噹粗苯原料中甲苯、二甲苯等重組分含量增加時,要相應地增加氫/油摩爾比;實踐證明其既能保證萊託爾繫統加氫催化劑正常運行,又能保證裝置運行的經濟性,解決瞭萊託加氫裝置加氫催化劑齣現早期活性下降現象的問題.

the mechanism of Litol system's hydrogenation reaction is analyzed,a concept of reaction equivalent ratio of H2 to oil is proposed.It indicates that enough reaction equivalent ratio of H2 to oil is necessary to maintain normal operation for the system.When heavy components such as toluene,xylene in crude benzene increase,the molar ratio of H2 to oil should be increased accordingly.The practice shows if the hydrogenation catalyst in Litol system runs normally and also commercially.The problem of early activity decline of hydrogenation catalyst in Baosteel Litol system is resolved.
