The objective is to develop and evaluate novel homogeneous catalytic systems for the selective conversion of low H/sub 2//CO-ratio syngas to alcohol fuel extenders. Under Task I, screening of several types of additives with ruthenium catalyst systems has continued. The basic objective of this effort is to modify the catalyst systems so that higher alcohols can be produced directly from syngas. Efforts are therefore directed toward increasing the total activity of the systems so that a lower operating pressure can be realized. At the same time, studies are being directed toward increasing the C/sub 2/+ alcohol selectivity of the systems. For task III, further investigations have been carried out in an effort to gain basic information on the catalytic chemistry involved in the novel methanol homologation system. Earlier work in this project has shown the importance of specific catalyst additives in the new homologation system. Further work has now been carried out on additives similar to one of these, A25, both to learn about the essential characteristics of this additive and to try to further enhance the rate and selectivity with a different additive. Several more additives of this type have now been found to effectively promote the methanol homologation reaction. It appears that we have now identified the important factors leading to good A25-type additives. Our plan is to synthesize more additives that fall within this class with the goal of optimizing the desirable structural and electronic properties, and progress has been made in developing a general synthetic route to such compounds.
