Carbon supported perovskite-like CsCuCl3 nanoparticles: A highly active and cost-effective heterogeneous catalyst in the hydrochlorination of acetylene to vinyl chloride

Abstract

Non-mercuric catalysts in acetylene hydrochlorination reaction have been gained much attention. Cu-based catalyst is low cost, green and stable, however, the lower activity than mercury catalyst limits its practical application. In this paper, we report activated carbon supported perovskite-like CsCuCl3 nanoparticles as a catalyst for hydrochlorination of acetylene. Cu-Cs/AC with 1 wt% Cu content performs superior activity than pure Cu/AC and even Hg/AC. At the condition of 200 °C and 50 h-1 of industrial space velocity, C2H2 conversion maintains 92% over 200 h. Our findings suggest that the low-cost Cu-Cs/AC catalyst can be envisioned as a viable alternative to commercial toxic HgCl2 for acetylene hydrochlorination.
