Hydro-refining catalyst, carrier for use therein and method for production thereof |
摘要 |
A method for producing a hydrorefining catalyst of the present invention has a step of preparing an aluminum solution containing phosphorus in a molar ratio of 0.001 to 0.05 with respect to aluminum; a step of neutralizing the prepared aluminum solution to produce a pseudo-boehmite powder; a step of forming the pseudo-boehmite powder followed by performing calcination at a temperature of not less than 650° C. to obtain a carrier; and a step of carrying a hydrogenation-active metal on the pseudo-boehmite powder or the carrier. The dispersion of the concentration distribution of phosphorus in the carrier of the obtained catalyst is within 10%. This method makes it possible to obtain the hydrorefining catalyst which has a practically sufficient mechanical strength and which has an excellent activity.
