Abstract:
A set of Ni–Mo bimetallic catalysts based on Ni/ZSM-23 with an initial Ni content of 5 wt % has been synthesized. The catalysts have been tested in the hydrotreating of a mixture of fatty acids (C16–C18) in a flow reactor at a temperature of 300°C, a pressure of 2.5 MPa, and WHSV = 8.4 h−1. The effect of the metal ratio on the activity, isoalkane selectivity, and stability of the catalysts in the hydrotreating of a fatty acid mixture has been shown. The highest deoxygenating capacity and the highest isoalkane yield have been found in the presence of a catalyst with a Mo/(Ni + Mo) ratio of 0.25, in which, according to XPS, the Mo/(Ni + Mo) ratio on the surface is 0.4.
