摘要：Palladium-based catalysts were prepared by an incipient wetness impregnation method, and the catalytic activity for the hydrochlorination of acetylene was studied in a fixed-bed reactor under normal pressure. Several analysis methods including scanning electron microscope (SEM), gas chromatography-mass spectrometry (GC-MS), N2-adsorption, thermogravimetry (TG), and inductively coupled plasma-atomic emission spectrometry (ICP-AES) analysis methods were combined to study the reasons for the deactivation of PdCl2/C catalyst in detail. On this basis, some attempts were made to improve catalyst stability and its regeneration.
