Abstract
PURPOSE: To prepare the catalyst and the catalyst support having an emptied or a densified central portion formed in a particle by a method wherein a special binding agent is mixed to γ-alumina or amorphous silica and pulverized and, after granulating and drying, baking is carried out.
CONSTITUTION: To a powder obtained by mixing γ-alumina and amorphous silica in a ratio of 9:1W1:9, if necessary, to a cpd. of Co or Mo and an oxide powder such as zeolite, Fe or Zn, a special binding agent is mixed in an amount of 2W8% and, thereafter, the mixture is pulverized to a powder of 65 mesh and the obtained powder is mixed to spherical or polygonal cores with 0.5W15m/m. Thereafter, this mixture is dired and baked at 500W1,350°C. Thereby, because a central portion of particles is emptied or densified, the catalyst support and the catalyst with adjustable density and surface area can be produced and the reaction is carried out efficiently.
