Abstract
Official abstract text for this publication.
The invention relates to a process for preparing a paraffin product from a carbonaceous feedstock comprising (a) partial oxidation of the carbonaceous feedstock to obtain a mixture comprising hydrogen and carbon monoxide, (b) performing a Fischer-Tropsch reaction using the mixture as obtained in step (a) and recovering an off-gas from the Fischer-Tropsch reaction and a paraffin product, (c) subjecting at least a part of the off-gas from the Fischer-Tropsch reaction to conversion using a catalyst comprising iron, or a catalyst comprising iron and chromium, followed by a hydrogenation step (d) using a steam/off-gas mol ratio in the range of between 0.5 and 1.5 and a catalyst comprising copper and zinc, followed by a conversion step (e) using a nickel based catalyst, and (f) preparing a hydrogen comprising gas from at least a part of the off-gas from the Fischer-Tropsch reaction.
First claim
