  • Procedure to prepare a supported trimetallic catalyst for production of ultra low sulfur diesel and its application
    Patent number: 10974229
    Abstract: According to this invention, a Ni—Mo—W trimetallic catalyst supported on porous alumina is obtained that shows very high activity for hydrotreating (HDT) of gasoils, particularly deep hydrodesulfurization (HDS) and hydrodesnitrogenation (HDN) of straight run gasoil in conditions of moderate pressure. When the catalyst is applied to HDT of diesel, the NiMoW catalyst exhibits high catalytic activity. The content of sulfur and nitrogen in the resulting diesel can be reduced from 13,200 to 10 ppm and nitrogen from 360 ppm to less than 1 ppm, under moderate pressure, temperature and space-velocity (LHSV) similar to those of an industrial unit.
