A COMPACT CATALYTIC REACTOR (10) FOR FISCHER-TROPSCH SYNTHESIS DEFINES A MULTIPLICITY OF FIRST AND SECOND FLOW CHANNELS ARRANGED ALTERNATELY IN THE REACTOR, FOR CARRYING A GAS MIXTURE WHICH UNDERGOES FISCHER-TROPSCH SYNTHESIS, AND A COOLANT FLUID, RESPECTIVELY. EACH FIRST FLOW CHANNEL CONTAINS A REMOVABLE GAS-PERMEABLE CATALYST STRUCTURE INCORPORATING A METAL SUBSTRATE. A MULTIPLICITY OF FLOW PATHS ARE DEFINED THROUGH THE CATALYST STRUCTURE, AND THE VOIDAGE, THAT IS TO SAY THE PROPORTION OF THE CROSS-SECTIONAL AREA OF THE FIRST FLOW CHANNEL CONSTITUTED BY THE SAID MULTIPLICITY OF FLOW PATHS, IS BETWEEN 25% AND 75%. THIS PROVIDES AN OPTIMUM BALANCE BETWEEN PRODUCTIVITY AND SELECTIVITY, SO THAT OPERATION OF THE REACTOR CAN BE ECONOMIC AND CONTROLLABLE.
