<P>PROBLEM TO BE SOLVED: To improve catalytic activity and thermal stability of an alumina-supported Cu catalyst containing CuO and CuAl<SB POS="POST">2</SB>O<SB POS="POST">4</SB>. <P>SOLUTION: A catalyst includes Al<SB POS="POST">2</SB>O<SB POS="POST">3</SB>and at least one metal component selected from Zr, Ti, Hf and Rf as a carrier. Firing is carried out at a first firing temperature to produce a first intermediate, and it is fired at a second firing temperature to produce the catalyst. CuO and CuAl<SB POS="POST">2</SB>O<SB POS="POST">4</SB>are supported on the carrier. <P>COPYRIGHT: (C)2012,JPO&INPIT |
