Title: The economical production of alcohol fuels from coal-derived synthesis gas. Quarterly technical progress report No. 15, April 1, 1995--June 30, 1995

Abstract

In Task 1, during this reporting period, the plug-flow reactor used for sulfided systems was converted to a Berty-type reactor. Subsequent to the conversion, we stopped screening sulfide catalysts. Prior to the conversion, six sulfide catalysts were prepared and evaluated: MoS{sub 2}, K{sub 0.7}MoS{sub 2}, Rb{sub 0.7}MoS{sub 2}, Cs{sub 0.7}MoS{sub 2}, Fe{sub 1-x}S/SiO{sub 2} and K{sub 0.8}Fe{sub 1-x}S/SiO{sub 2}. These catalysts were all produced by vapor-phase reactions, followed by alkali addition using incipient wetness techniques. The alkali/molybdenum catalysts all satisfied the project requirements for product selectivity and activity. The iron sulfides were poor catalysts, with conversion rates less than 1% and product distributions strongly favoring hydrocarbons. Materials produced subsequent to the conversion were all transition-metal nitrides or carbides. We tested a commercial Zn/Cr catalyst support, both bare and impregnated with potassium and cesium at various loadings. None of these catalysts looks promising for the production of higher alcohols. We also manufactured two new Zn/Cr supports which are available for testing now.
