Methanol synthesis catalysts from intermetallic precursors: Binary lanthanide—copper catalysts

The methanol synthesis activity of a series of catalysts derived from copper—lanthanide intermetallic precursors has been investigated. Activation of theprecursors was carried out in CO/H 2 at pressures up to 50 bar and temperatures in the range 373–533 K. Methanol synthesis was observed at temperat...

Description
Summary:The methanol synthesis activity of a series of catalysts derived from copper—lanthanide intermetallic precursors has been investigated. Activation of theprecursors was carried out in CO/H 2 at pressures up to 50 bar and temperatures in the range 373–533 K. Methanol synthesis was observed at temperatures as low as 373 K. A stable activity of 25 moles of methanol per kilogram of catalyst per hour was obtained for a catalyst derived from CeCu 2. XRD and TEM analysis has shown that discharged catalysts contain large crystallites of copper (400–800Ådiameter) and the corresponding lanthanide oxide; methanol activity does notappear to correlate with copper crystallite size and BET N 2 isotherms gave total surface areas of
