Conventional sintering measurement techniques

Several Pd-Pt (Pd Pt=4 l) catalysts for deep hydrodesulfurization (HDS) were prepared using a commercial amorphous silica-alumina (ASA), a novel mesoporous silica (MPS) and a novel mesoporous silica-alumina (MPSA) as carriers with dispersions of > 50%. They were characterized by various techniques and their performance in deep HDS of 4-ethyl, 6-methyl-dibenzothiophene measured at 633 K and 6.0 MPa in the presence of carbazole and H2S. The Pd-Pt catalysts showed good activity as compared to typical conventional HDS catalysts. Their activity decreased with a decreasing Al content in the support (thus support acidity) ASA > MPAS > MPS. Enhanced support acidity seems to favor the stabilization of the dispersed metal particles against sintering. [Pg.1019]
