Reactors used for catalytic hydrogenation催化加氢反应器 Three types of reactor are used: (1) fixed-bed reactors固定床反应器; (2) fluidized-bed reactors流化床反应器 and (3) slurry reactors.浆态床反应器 Hydrotreating: trickle-bed reactor 1. The processes can be categorized by the fate of the organosulfur compounds during desulfurization, the role of hydrogen, or the nature of the process used (chemical and/or physical). whether the sulfur compounds are decomposed, separated from refinery stream without decomposition, 2. When organosulfur compounds are decomposed, gaseous or solid sulfur products are formed and the hydrocarbon part is recovered and 1. The processes can be categorized by the fate of the organosulfur compounds during desulfurization, the role of hydrogen, or the nature of the process used (chemical H2 and S rich oil are trickled thro catalyst bed * * * * * * * * 石油炼制工程 厦门大学化工系:贾立山 Hydrodesulfurisation (HDS)加氢脱硫 Hydrodenitrogenation (HDN)加氢脱氮 Hydrodeoxygenation (HDO) and (HDM) 加氢脱氧和加氢脱金属 PROCESS加工工艺 Catalytic cracking催化裂化 Hydrocracking 加氢裂化 Catalytic Reforming 催化重整 Hydrotreating 加氢处理 PROCESSES IN REFINERIES炼油工艺 Market share of main catalysts technology divisionsin percentage in terms of sales value催化剂市场份额 环境 炼油 加氢裂化 重整 异构化 加氢处理 流化催化裂化 其它化学品 Hydrodenitrogenation (HDN)加氢脱氮 Hydrodesulfurization （HDS)加氢脱硫 Hydrodeoxygenation (HDO)加氢脱氧 Hydrodemetallization (HDM)加氢脱金属 HYDROTREATING加氢处理 Hydrotreating加氢处理: A process used in the oil industry to remove objectionable elements such as nitrogen sulfur, oxygen and metals from petroleum distillates by reacting them with H2 over a catal
