Fourteen catalysts were prepared by either evaporation of metal nitrate-citric acid solutions or by impregnation of inert supports with metal nitrate-citric acid solutions. Fourteen catalysts were tested in either the Berty gradientless reactor or the plug-flow reactor. These catalysts have been characterized intto the following five groups: Group I - catalysts containing Cu, Zn, Co, Cr and alkali; Group II - catalysts of Group I without Zn or Co or Cr; Group III - modified methanol synthesis catalysts of substituted by transition metals such as Fe, Mn, Ti, Th, etc; and Group V - catalysts of Groups I, II or IV supported on refractory cements such as silica or titania. Although none of the catalysts tested this quarter resulted in reaching the targetted oxygenates selectivities and space time yields, the following relevant observations were made: Transition metals in a catalyst having the general atomic formula CuZn/sub 0/ /sub 125/CoK/sub 0/ /sub 11/M and produced by evaporation of metal nitrate - citric acid solution affect oxygenates selectivity as indicated below (in descending order), Fe approx. Cr > V >> Mn; Potassium in a catalyst having the formula Cu Zn/sub 0/ /sub 125/CoA/sub 0/ /sub 11/ is a better alkali promoter than …

Praxis is the practice of the programming art, science, and skill. It is a high-order language designed for the efficient programming of control and systems applications. It is a comprehensive, strongly typed, block-structured language in the tradition of Pascal, with much of the power of the Mesa and Ada languages. It supports the development of systems composed of separately compiled modules, user-defined data types, exception handling, detailed control mechanisms, and encapsulated data and routines. Direct access to machine facilities, efficient bit manipulation, and interlocked critical regions are provided within Praxis.

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 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.
