PURPOSE:To obtain a highly active catalyst for hydrogenating light oil under reduced pressure, by specifying the pore characteristics of a catalyst prepared by supporting a molybdenum component and a cobalt component by a carrier comparising alumina-baria. CONSTITUTION:The pore characteristics of a catalyst prepared by supporting a cobalt component and a molybdenum component by a carrier comprising alumina-boria are specified as stated hereinbelow. That is, an average pore size of pores within a range between 0-600Angstrom pore size is 70-100Angstrom , the sum of pore volume with of 70-100Angstrom pore size is 70% or more of that of the sum of the volume a pore with 0-600Angstrom pore sizes, the sum of the pore volume with 0-60Angstrom pore sizes, the average size of the pores with 62-600Angstrom pore size is 20% or less of that of the sum of the pore volume of 0-600Angstrom pore sizes measured by a mercury pressure method is 70-100Angstrom , the sum of the pore volumes of pores with an average pore size of + or -10Angstrom is 60% or more of that of the fine pore with a diameter of 62-600Angstrom and the volume of the fine pore with (an average pore size of + or -10Angstrom or more) is 15% or less of that of sum of the pore volume with 62-600Angstrom pore sizes. By this pore characteristics, a highly active hydrogenation catalyst is obtained. |
