Development of a catalyst for conversion of syngas-derived materials to isobutylene. Technical progress report No. 6, July 1, 1992--September 30, 1992
Goal is to develop a catalyst and technology that will produce iC{sub 4}{double_bond} directly from coal-derived syngas and that is capable of using a lower H{sub 2}/CO ratio (0.5 to 1.0). This report covers the testing of various zirconia (ZrO{sub 2}) based catalyst systems designed to examine effects of catalyst preparation and process variables, especially feed additives. Testing sol-gel ZrO{sub 2} catalysts calcined at 475 C instead of 500 C increases the isobutene yield. Supporting zirconia on high-surface-area sol-gel silica or silica-alumina results in low activity catalysts. Addition of ethylene, propylene, ethanol to feed produces hydrogenation, dimerization, and metathesis products, but little or no isobutene.
