采用浸渍法制备了活性炭负载铋无汞催化剂,并通过X射线衍射、氮气物理吸附、透射电镜、扫描电镜和X射线电子能谱等方法对催化剂进行了表征。对催化剂进行了催化乙炔氢氯化反应性能的研究,结果表明,催化剂对乙炔氢氯化反应具有良好的催化性能,活性组分主要以BiOCl的形式存在于催化剂表面。反应过程中积碳的产生使得催化剂活性有所降低。 The catalyst was characterized by X-ray diffraction, nitrogen adsorption, TEM, SEM and X-ray photoelectron spectroscopy. The catalytic performance of the catalyst for the acetylene hydrochlorination was studied. The results show that the catalyst has good catalytic activity for the acetylene hydrochlorination. The active component mainly exists in the form of BiOCl on the catalyst surface. The reaction of carbon deposition during the catalyst activity decreased.
