The self-poisoning of ruthenium silica catalyst has been studied for benzene hydrogenation and n-pentane hydrogeolysis. The catalysts were synthesized by the sol-gel method, which consists of adding the active metal to a sol followed by transformation to a gel. As a reference, a catalyst has been prepared by the classical impregnation method using commercial silica. In the hydrogenation of benzene, the catalysts prepared by the sol-gel method are more resistant to deactivation by carbonaceous residues. The opposite effect was observed for the hydrogenolysis of n-pentane. Deactivation by thiophene for benzene hydrogenation is practically the same for the sol-gel and the reference catalysts.
