Hydrodechlorination catalyst and preparation method of chlorotrifluoroethylene

The present invention relates to a hydrodechlorination catalyst and a preparation method of a chlorotrifluoroethylene. The hydrodechlorination catalyst comprises a carrier, a main catalyst and an auxiliary agent; the main catalyst and the auxiliary agent are loaded on the carrier, the main catalyst is Pd and Cu, Sn or Mn is added to the auxiliary agent to inhibit agglomeration, and the loading capacity is optimized. The method adopts the hydrodechlorination catalyst to prepare chlorotrifluoroethylene. The catalyst disclosed by the invention is good in stability, high in activity, friendly to reaction selectivity and applicable reaction temperature and long in service life, and is more beneficial to industrial scale production when being used for preparing chlorotrifluoroethylene. 本发明涉及一种加氢脱氯催化剂及三氟氯乙烯的制备方法，加氢脱氯催化剂包括载体、主催化剂和助剂，主催化剂和助剂负载于载体上，主催化剂为Pd和Cu，助剂添加Sn或Mn以抑制团聚，并对负载量进行优化。该方法采用上述加氢脱氯催化剂制备三氟氯乙烯。本发明中的催化剂稳定性好、活性高、反应选择性和适用反应温度友好、寿命长，用于制备三氟氯乙烯时，更有利于工业规模生产。
