Summary:

Goal is to develop a catalyst and technology that will produce iC₄{double_bond} directly from coal-derived syngas and that is capable of using a lower H₂/CO ratio (0.5 to 1.0). This report covers the testing of various zirconia (ZrO₂) based catalyst systems designed to examine effects of catalyst preparation and process variables, especially feed additives. Testing sol-gel ZrO₂ 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.
