Popis: A novel N-promoted carbon nanotubes (CNT) supported Pd catalyst (PANI/CNT-Pd) was prepared by the ultrasonic-assisted impregnation method and applied in the acetylene hydrochlorination reaction successfully. Compared with the Pd-CNT catalyst, the PANI/CNT-Pd catalyst exhibited the enhanced catalytic performance with more than 91.6% acetylene conversion and 99.6% vinyl chloride selectivity during 20 h at T = 160 °C, GHSV(C2H2) = 120 h-1 and V(HCl) : V(C2H2) = 1.5. It is suggested that PANI species contained N elements have been deposited on the CNT surface and they display the critical role on the enhanced catalytic performance of PANI/CNT-Pd catalysts correlated with the less palladium loss and the carbon deposition.
