Title: Difference in mechanisms of syntheses from CO and H/sub 2/ on copper-containing oxide and metallic catalysts
Abstract: The kinetics of the synthesis of methanol and higher alcohols and hydrocarbons from CO and H/sub 2/ on the industrial catalyst SNM-1, a copper-zinc-aluminum oxide catalyst, with small amounts of iron (approx. 0.5 to 2.0%) added were studied to ascertain whether the synthesis products formed directly from CO/sub 2/ and H/sub 2/ or through the intermediate formation of CO. Tests with both modified and unmodified catalyst indicated that the addition of iron led to the formation of organic compounds without the intermediate formation of CO. Rates of formation of the products were noted to depend identically on the concentration of the reaction products which increased with increasing contact time. Reactions of the systems CO, CO/sub 2/, and H/sub 2/ with larger amounts of iron (up to 2%) were found to yield predominately the higher alcohols and hydrocarbons. Purification of the reacting gases to eliminate all traces of CO/sub 2/ and H/sub 2/O caused all reactions to cease; but when the purification ceased, synthesis was renewed with the former yield.
