The objective of the contract is to develop and evaluate novel homogeneous catalytic systems for the selective conversion of low H/sub 2//CO syngas to alcohol fuel extenders. Progress reports are presented for Task 1, modification of ruthenium catalyst system, and Task 3, further study of superior catalysts. As reported in the previous quarter, the use of a novel metal-containing additive, A38, in the catalytic system of ruthenium carbonyl/molten phosphonium salt causes the activity of the system to increase substantially. Even at the relatively low syngas pressure of 3000 psi, the activity of the system was quite respectable. We have now found that addition of the precursors of A38 to a ruthenium catalyst system gives similar, but slightly inferior results. The addition of organic additive A58 was found to enhance the production of C/sub 2/ products such as ethanol, and increased activities were also observed. Research in Task 3 has been conducted on the novel methanol homologation system which produces ethanol and other products under relatively low pressures. Studies of the catalyst chemistry have been carried out, with an emphasis on the involvement of catalyst precursors in the catalytic chemistry. The effects of using related and different catalyst precursors have been investigated, and these studies are continuing. 8 tabs.
