We continued to investigate the direct conversion of syngas to alcohols using promoted ruthenium catalysts because of their good overall catalyst activities. Our objective is to improved the catalyst system so that fuel alcohols with substantial amounts of higher alcohols (C/sub 2+/ alcohols) can be produced at low pressure. In the last quarterly report, we reported that additive A9 may be beneficial to the above catalyst system, increasing not just the C/sub 2+/ alcohols but also the C/sub 3+/ alcohols. We have done a few more experiments and the results again suggest that A9 is indeed beneficial for the formation of C/sub 3+/ alcohols. Furthermore, we found that the activity of the catalyst system can be restored to the original level by increasing the amount of other promoters used. It was also found that when iodide was replaced by the phosphonium halide, P(n-Bu)/sub 4/Br, the amount of C/sub 3+/ alcohols also increased. We have started the screening of other metal complexes in the hope that we can increase the total activity of the catalyst system of Ru/A16/I-/A92. The initial results, however, have not been encouraging. 4 figs., 14 tabs.
