Abstract: Derivative temperature-programmed reduction spectra(DTPR)were first proposed.In order to obtain DTPRspectra from experiments, a series of computer programs was edited in ASSEMBLEand SOFT BASIClanguages.With the aid of computer, the DTPRspectra of Cu-based catalysts for methanol synthesis were successfully obtained.Although it was very difficult to know how many kinds of of Cu oxide species there are in the Cu/Zn/Al catalyst(Sanming Chemical Factory)from TPRspectrum, The DTPRspectra showed obviously that there were three kinds of Cu oxide species in the catalyst.Both TPRand DTPRshowed there was one kind of Cu oxide species in MK-101 Cu/Zn/Al catalyst(Topose).The results indicated that MK-101 was easier to be reduced and more homogeneous than the catalyst of Sanming Chemical Factory, It has been found that the resolving power of DTPRis better than that of TPR.
