Patent ID: 7985706

Claim:
An uniformly, highly dispersed metal catalyst, comprising: a catalyst carrier made of a metal oxide; and a catalyst metal having catalytic activity, the catalyst metal being loaded on the catalyst carrier, wherein: the catalyst carrier is a sulfur-containing catalyst carrier which comprises an aluminum carrier having a surface area of 150 m 2 /g or larger, a fine pore volume of 0.4 cm 3 /g or larger, an average fine pore diameter of 40 to 300 Å, and the proportion of fine pores having an average fine pore diameter of 30 Å is 60% or higher with respect to a total pore volume and sulfur or a sulfur compound which is dispersed throughout a cross section of the aluminum carrier and whose content is 0.15 to 3.0% by weight in terms of a sulfur element; and in the sulfur-containing catalyst carrier, platinum or rhodium is dispersed and loaded as the catalyst metal over an entire cross section of the catalyst carrier substantially in agreement with distribution of the sulfur or the sulfur compound.
