Bartholomew, C. H.

From the literature, three major catalyst problems are apparent which relate to stability: sulfur poisoning, carbon deposition with associated plugging, and sintering. Our understanding of these problems is at best sorely inadequate, and the need to develop new and better catalyst technology is obvious. Nevertheless, there has been very little research dealing with new catalyst concepts such as bimetallic (alloy) or monolithic-supported catalysts for methanation. This study deals specifically with sulfur poisoning, carbon deposition, and the effects of support (monolith and pellet) geometry on the performance of alloy methanation catalysts. The effects of carbon deposition and in-situ exposure to 10 ppM H/sub 2/S during reaction on the methanation activity of pelleted and monolithic alumina-supported Ni, Ni-Co, Ni-MoO/sub 3/, Ni-Pt, Ni-Rh, and Ni-Ru were investigated. These and other significant results are presented and discussed.
