Abstract:

The experimental investigation conducted during Phases 1, 2, and 3 of this in-house research program demonstrated conclusively that four catalysts effectively reduced carbon dioxide to methane and water at high yield and low temperature. The four catalysts were nickel-on-kieselguhr from Phase 1 cobalt-on-alumina from Phase 2 and ruthenium and rhodium each supported on aluminum oxide from Phase 3. Three reactors of varying length-to-diameter ratio in the range of 1 1 to 181 were used in the three phases to evaluate the catalysts. Phase 4 was planned and conducted with the approach of evaluating each of the above four catalysts in the reactors used in Phases 2 and 3. These reactors have a length-to-diameter ratio of 51 to 181 respectively. The objective of Phase 4 was to determine the effect of varying reactor length-to-diameter ratio and reactor internal volume on the effectiveness of each of the four catalysts on the yield of the methanization reaction. The optimum catalyst-reactor combination was demonstrated to be 0.5 ruthenium-on-alumina in the reactor having an LD ratio of 181. A yield of 99 was obtained at the minimum temperature of 427 F.
