Catalytic dehydrogenation of a mixture of C10–C14n-paraffins to linear C10–C14 monolefins in a supercritical phase

Abstract

The catalytic dehydrogenation of a mixture of C₁₀–C₁₄n-paraffins (n-alkanes) to linear C₁₀-C₁₄ monolefins (alkenes) over a commercial Pt-Sn/γ-Al₂O₃ catalyst was observed to be two to three times higher in a supercritical phase of the reactant themselves than in the gas phase; this indicated that the thermodynamic equilibrium was strongly shifted under supercritical conditions.
