Abstract
A process for the production of isoparaffins having 4 to 7 carbon atoms per molecule from synthesis gas comprising the following steps: PA1 a) Synthesis of a heavy paraffins-containing hydrocarbon mixture over a Fischer-Tropsch catalyst; PA1 b) Conversion of at least part of the heavy paraffins-containing hydrocarbon mixture over a bi-functional isomerization/hydrocracking catalyst under isomerization/hydrocracking conditions; PA1 c) Separation of normal paraffins from at least part of the isoparaffins-containing product of step (b); PA1 d) Recycling at least part of the normal paraffins to step (b) and withdrawing C.sub.4 -C.sub.7 isoparaffins as a product from the process.
