A process for the production of isoparaffins having 4 to 7 carbon atoms per molecule from synthesis gas comprising the following steps: a) Synthesis of a heavy paraffins-containing hydrocarbon mixture over a Fischer-Tropsch catalyst; b) Conversion of at least part of the heavy paraffins-containing hydrocarbon mixture over a bi-functional isomerization/hydrocracking catalyst under isomerization/hydrocracking conditions; c) Separation of normal paraffins from at least part of the isoparaffins-containing product of step (b); d) Recycling at least part of the normal paraffins to step (b) and withdrawing C4-C7 isoparaffins as a product from the process. <IMAGE> |
