FIGURE 9 Stability of Cu/ZnO/Ti CMNR in methanol
dehydrogenation. (Reaction temperature 360 ℃, gas flux 8
m3·m-2·h-1 through
the membrane, one sheet of membrane of thickness 1mm)
The catalytic reaction parameters of methanol dehydrogenation with
different catalysts (from literatures and this work), including reaction
temperature, TOF , YFA andYH , were illustrated in Table 2. The reportedTOF s ranged from 0.4
mmol·h-1g-1 to 130
mmol·h-1g-1, theYFA and YH both ranged
from 0.8 ~ 1.8
mmol·h-1·mm-1, depending on the
different reaction temperature and loading amount of catalyst. TheTOF, YFA and YH for
methanol dehydrogenation in Cu/ZnO/Ti CMNR developed in this work were
much higher than the reported values in literatures. It could be
concluded that the Cu/ZnO/Ti CMNR had better catalytic performance for
methanol dehydrogenation.
