K. Murata et al., Hydrogen production by decomposition of light paraffins over Ni/Ca/carbon catalysts in the absence or presence of impurities, REACT KIN C, 73(2), 2001, pp. 297-305
The decomposition of light paraffins was investigated using a Ni/Ca/carbon-
based catalyst and an Ag-Pd membrane-type reactor (PMR). The use of this co
mbined system resulted in the formation of smaller amounts of methane (< 10
% yield) than in fixed-bed reactor systems (10-50% yield). The initial acti
vity of CH4 decomposition seems to be little affected by these impurities s
uch as NO, SO2, CO2, and H2O. The activity in the presence of SO2, however,
was found to be completely lost after 250 min.
