| The production of syngas from methane by catalytic partial oxidation (CPO) over noble metal catalysts allows for millisecond contact time. These systems exhibit high temperature and concentration gradients making direct measurements difficult at industrially relevant conditions. However, performing scientific measurements as close as possible to conditions seen in industrial application of CPO are important to obtain reliable data for later scale-up. These conditions dictate elevated pressures where homogeneous chemistry comes into effect in addition to the heterogeneous catalytic reactions. In this work we present measurements sampling inside the reactor at pressures up to 1.1MPa with minimal disturbance of the system. The spatial resolution of these measurements is determined by the characteristic length of the support (~300μm) and not the technique itself. It is shown that maintaining the flow rate and increasing the pressure allows one to obtain effluent values closer to equilibrium than is observed at atmospheric pressure. |
