<p>A reactor comprising a catalyst bed (1) having a central longitudinal axis, which catalyst bed has an upstream surface (2) perpendicular to the central longidutinal axis, and a distribution chamber (4) for directing a gaseaous mixture of reactants to the upstream surface (2) of the catalyst bed (1), which distribution chamber (4) has an inlet (5) for tangentially introducing the mixture into the distribution chamber (4), the distribution chamber (4) being defined by the upstream surface (2) of the catalyst bed (1), a sife surface (6) having a central longitudinal axis that coincides with the central longitudinal axis of the catalyst bed (1), and a covering surface (7) formed such that the distance between the upstream surface (2) of the catalyst bed (1) and the covering surface (7) is monotonically decreasing towards the central longitudinal axis. The invention further relates to a fuel cell system comprising such a reactor and a fuel cell and to a process for the catalytic oxidation of hydrocarbonaceous fuel using such a reactor.</p> |
