Abstract
The formation of a molybdenum oxycarbide active for catalytic isomeriz ation of alkanes is strongly dependent on the total pressure of reacta nts. High pressures of the hydrogen/hydrocarbon mixture (up to 40 bar) increase the rate of reduction of MoO3 and the rate of diffusion of c arbon into the bulk, this favors the formation of the oxycarbide at th e expense of MoO2.
