The catalytic activity and durability for the CO2 reforming of methane was studied on a Ni/Al2O3 catalyst prepared using water-in-oil (w/o) microemulsion. The initial activity of the Ni/Al2O3 catalyst thus prepared was higher than that of an impregnated one. The impregnated catalyst deactivated with time-on-stream due to severe coking. In contrast, the catalyst prepared using w/o microemulsion kept its activity for 50 hr and caused little coking at a CO2/CH4 molar ratio > 1.4:1. The carbon species deposited on the catalyst prepared using w/o microemulsion was less crystallized than that on the impregnated one. The superior resistance of the catalyst to carbon deposition is attributed to the generation of such a carbon species.
