By far the largest prodn of acet in the USA is from petroleum-derived propylene by way of isopropanol (Refs 31 48). Another method is to pass acetylene and steam over FeaOj-ZnO catalyst at elevated tempsfRef 48). In Germany acet was produced in 95% yield from AcOH by a vapor-phase catalytic process using a cerium oxide catalyst at 400 Ref 31) There are also other methods of prepn(Refs 1,2,3,4,10,14,31,33,42,47, ...

A series of manganese-cerium oxide catalysts with different Mn/Ce atomic ratios was prepared by thermal decomposition of amorphous citrate precursors [5]. The samples were prepared by varying the ratio between the manganese and cerium salts. 

Investigation of copper-cerium oxide catalysts in the combustion of diesel soot... 

The combustion of diesel soot has been studied in presence of copper-cerium oxide catalysts. These catalysts were prepared by impregnation of copper nitrate on ceria and calcination under air up to 1073 K. The solids were widely characterised by electron paramagnetic resonance (EPR) technique. For an atomic ratio Cu/Ce=l and a calcination temperature of 673 K, the catalyst seems to be t e most active in the combustion of diesel soot, when compared to other catalysts. The Cu monomers are more concerned than the dimers in this combustion. 

In this work, it is shown that the copper-cerium oxide catalysts are active in the diesel soot combustion reaction. The isolated Cu ions seem to be the most active sites in such catalysts. The activity depends on the copper concentration and the pre-treatment of solids. Among all the tested catalysts, the lCulCe673 oxide, calcined at a relatively low temperature and containing the highest copper concentration, is the most active. 

Recent research at the University of Minnesota by Lanny Schmidt and his coworkers suggests that corn could be a feasible source of hydrogen. In this process the starch from the corn is fermented to produce alcohol, which is then decomposed in a special reactor at 140°C with a rhodium and cerium oxide catalyst to give hydrogen. These scientists indicate that enough hydrogen gas can be obtained from a few ounces of ethanol to generate electricity to run six 60-watt bulbs for an hour.
