Development of a catalyst for conversion of syngas-derived materials to isobutylene. Technical progress report No. 5, March 31, 1992--June 30, 1992
The main goal of this contract is to develop a catalyst and technology that will produce iC4{sub 4}{sup =} directly from coal-derived syngas and that is capable of using a lower H{sub 2}/CO ratio (0.5 to 1.0). The research will identify and optimize the key catalyst and process characteristics that give improved performance for CO conversion by a non-Fischer-Tropsch process. This report, which is Quarterly Report No. 5 for contract DE-AC22-91PC90042, covers the testing of various zirconia (ZrO{sub 2}) and bismuth oxide (Bi{sub 2}O{sub 3}) based catalyst systems designed to examine the effects of catalyst preparation and process variables, especially the H{sub 2}/Co ratio. Testing of sol-gel ZrO{sub 2} catalysts with lanthanum (La) or yttrium (Y) addition indicates a decrease in isobutene yield. An attempt to increase catalyst surface area by impregnating Zr on a sol-gel SiO{sub 2} catalyst was unsuccessful. A Bi{sub 2}O{sub 3} catalyst was very low in activity as a result of complete reduction to Bi metal. Increasing the H{sub 2}/CO ratio to 2:1 slightly increased the isobutene yield and improved catalyst stability.
