Popis:	Zirconium oxide was synthesized by a modified sol-gel method, and was evaluated for the selective formation of isobutane and isobutene from synthesis gas. Due to increased basicity, zirconia from sol-gel preparation showed higher selectivities to iso-C[sub 4]'s while maintaining the same level of activity as zirconia prepared by calcination of zirconyl salts. The catalysts was further modified with Group I and II elements, and the activity tests showed increased iso-C[sub 4] and decreased methane production for the catalysts doped with potassium, magnesium, calcium, or barium. 29 refs., 10 figs., 1 tab.
