Method for removing dienes from a material stream containing C3 to C5 hydrocarbons by selective hydrogenation

The invention relates to a method for removing dienes from a material stream containing C3 to C5 hydrocarbons by selective hydrogenation at a predefined reaction pressure and a predefined reaction temperature in the presence of a hydrogenation catalyst, wherein the reaction pressure and the reaction temperature at the reactor inlet are controlled such that the reaction pressure at the reactor inlet differs by a maximum of 0.01 bar from the predefined reaction pressure and the reaction temperature at the reactor inlet differs by a maximum of 0.1 DEG C from the predefined reaction temperature, and the proportion of hydrogen supplied to the selective hydrogenation lies in the range from 2 to 20 mol per mol diene which is contained in the material stream containing the C3 to C5 hydrocarbons. 本发明涉及一种通过在氢化催化剂存在下在指定反应压力和指定反应温度下的选择性氢化从包含C至C烃的材料料流中除去二烯的方法，其中调节反应器入口的反应压力和反应温度以使反应器入口的反应压力不偏离指定反应压力大于0.01巴且反应器入口的反应温度不偏离指定反应温度大于0.1℃，并且供应给选择性氢化的氢气比例在包含C至C烃的材料料流中存在的每摩尔二烯2至20摩尔的范围内。
