Development of Alcohol-Based Synthetic Transportation Fuels From Coal-Derived Synthesis Gases. Fourth Quarterly Progress Report, July 1-September 30, 1980

PDF Version Also Available for Download.

Description

Twenty-four catalysts were prepared by either evaporation of metal nitrate-citric acid solutions, by impregnation of methanol synthesis catalysts or by coprecipitation with KOH. Seventeen catalysts were tested in either the Berty gradientless reactor or the plug-flow reactor. These catalysts have been characterized into the five groups. A CuCoZn/sub 0/ /sub 125/Fe/sub 0/ /sub 1/Th/sub 0/ /sub 5/K/sub 0/ /sub 11/ catalyst produced by evaporation of metal nitrate-citric acid solutions resulted in an oxygenates selectivity of about 50% (CO/sub 2/-free basis) at total CO conversions of the order of 5 to 15% per pass. The alcohols (including about 2% aldehydes) distribution … continued below

The alcohols (including about 2% aldehydes) distribution was 48.2% C/sub 1/; 33.4% C/sub 2/; 10.7% C/sub 3/; 5.3% C/sub 4/ and 2.3% C/sub 5/. The calculated heating value of this Alkanol mixture is about 78,000 Btu/gal (20% higher than that of methanol). The estimated clear Research Octane Number (RONC) of this mixture is 109. The estimated octane quality (RONC) of a mixture of 80% unleaded gasoline having an 80 RONC and 20% of the Alkanols is about 91.
