<p>Reactor A reactor for catalytic synthesis comprises a catalyst bed 18 cooled by coolant-carrying tubes 36 substantially vertically within it and having an inlet (16 or 23) and outlet (16 or 25) providing reactants flow transverse to coolant flow, the reactants flow area of the bed inlet being 0.5 to 2.0 that of the bed outlet. Reactants flow is preferably chordal between for example foraminate walled-off regions (20A, 20B or spargers (23, 25). Specifically a catalyst bed having inlet and outlet adiabatic regions and an intermediate cooled regions is preferred for methanol synthesis.</p> |
