Abstract
Disclosed herein is a process of preparing a catalyst having narrow particle size distribution and supported with monodispersed metal particles of which a particle size is about less than 20 .ANG.. In the present invention, propargyl alcohol is employed in place of a sulfur-containing agent for supporting the metal particles on a support thereby avoiding the contamination of the sulfur component and the high temperature treatment for decomposing the sulfur-containing agent. Accordingly, the resulting catalyst contains no sulfur contaminant and substantially no agglomerated metal particles.
