Abstract:
A process for preparing an activated metal fixed-bed catalyst, comprising:mixing at least one alloy powder of a catalyst metal and an extractable alloying component which is free of a pure catalyst metal with a high molecular weight polymer to form a shapable mixture, shaping the mixture to produce a freshly prepared shaped article, thermally treating said article at temperatures between 100 and 300Â° C. to remove the polymer through decomposition, calcining the freshly prepared shaped article at a temperature of less than 850Â° C., and activating the shaped article by extracting at least a portion of the extractable alloying component with an alkaline solution, wherein the high molecular weight polymer is a polyoxymethylene homopolymer or copolymer with a melt volume index MVI (according to DIN ISO 1133, measured at 190Â° C. with a load of 2.16 kg) from 1 to 50.
