A compact catalytic reactor comprises a stack of plates ( 72, 74, 75 ) to define a multiplicity of first and second flow channels arranged alternately in the stack; each flow channel in which a chemical reaction is to take place is defined by straight-through channels across at least one plate, each such straight-through channel containing a removable gas-permeable catalyst structure ( 80 ) incorporating a metal substrate. The first flow channels ( 76 ) are oriented in a direction that is perpendicular to that of the second flow channels ( 77 ), and between successive second flow channels in the stack the reactor defines at least three side-by-side first flow channels ( 76 ); and the reactor incorporates flow diversion means ( 80; 88 ) such that the first fluid must flow through at least three such first flow channels ( 76 ) in succession, in flowing from an inlet to an outlet. The overall flow paths can therefore be approximately co-current or counter-current. |
