| description | The invention relates to a method for treating a solid catalyst in a reactor containing a catalyst bed, said method comprising the following steps: a) carrying out a catalytic gas phase reaction in the reactor at a catalyst bed temperature T1, said catalytic gas phase reaction being carried out in the presence of a hydrogen halide or causing the formation of a hydrogen halide; b) flowing an inert gas through the catalyst bed at a catalyst bed temperature T2 below T1, wherein the temperature T2 is greater than 30 DEG C.
本发明涉及在含有催化剂床的反应器中处理固体催化剂的方法，所述方法包含以下步骤：a)在所述反应器中，在催化剂床温度T1下进行催化气相反应，所述催化气相反应在存在卤化氢的情况下进行，或者引起卤化氢形成；b)使惰性气体在低于T1的催化剂床温度T2下流动通过催化剂床，其中所述温度T2大于30℃。 |
