The work presents the results of comparative study of MoS2/Al2O3, CoMoS/Al2O3 and NiMoS/Al2O3 catalysts in the
aliphatic ethers hydro conversion and in the hydrotreating of rapeseed oil (RSO) and its mixtures with the straight-run gasoil (SRGO). The selectivity of aliphatic ether and RSO transformation depends on the composition of sulphide phase and the reaction conditions. The un-promoted MoS2/Al2O3 catalyst turns the reaction to HDO route, avoiding the formation of C15 hydrocarbons and CO/CO2 molecules. The CoMo/Al2O3 and NiMo/Al2O3 catalysts gave C16 and C15 hydrocarbons. The RSO addition decreased the activity of CoMoS/Al2O3 catalysts but had no effect on the activity of NiMoS/Al2O3 in the HDS and HDN reaction. The CO molecules formed as a result of RSO hydroconversion can be considered as a main inhibitor of CoMoS/Al2O3 catalyst’s activity. So, the chemical composition of sulphide phases effects strongly on the behaviour of sulfided catalysts in the hydrotreating of triglyceride-based feedstocks.
