In this study, the novel tin-based catalysts (Sn(II)/PN@AC) were prepared using the phosphorus and nitrogen dual-modified activated carbon as support and SnCl2 as active compounds, as well as then evaluated in acetylene hydrochlorination. Under the reaction temperature of 180°C and an acetylene gas hourly space velocity (GHSV-C2 H2) of 30 h–1, the 15%Sn(II)/PN@AC-550 showed the initial acetylene conversion of 100% and vinyl chloride selectivity over 98.5%. Additionally, the deactivation rate of 15%Sn(II)/PN@AC-550 reached 0.47% h–1, which was lower than that of 15%Sn(II)/AC-550 (1.

Abstract Red mud is a residue in the production of alumina by the Bayer process. It contains oxides of iron and titanium, and has been shown to be active in sulfided form as hydrogenation catalyst. The evolution of sulfided red mud activity and selectivity with reaction time was studied for the hydrogenation of a light fraction of an anthracene oil.
