Process for the preparation of hydrogen by reacting a feed gas comprising methane and carbon monoxide with steam in the presence of a steam reforming catalyst at a pressure of at least 15 bara in the heated zone of a steam reformer to obtain a raw hydrogen containing product stream, wherein (a) the feed gas is mixed with the steam before entering the steam reformer resulting in a reaction mixture of the feed gas and steam having a temperature below 540&#xb0; C.; and (b) the reaction mixture obtained in step (a) is fed into the heated zone of the steam reformer where it is first contacted with an inert material before it is contacted with the steam reforming catalyst.

Process for the preparation of hydrogen

The present invention relates to a method for obtaining a hydrogen rich gas from an off gas. Further, the invention relates to a system for operating said method.

Method for treating off gas and producing hydrogen

The present invention relates to a process for processing a gas mixture comprising methane, carbon dioxide, carbon monoxide, hydrogen, nitrogen, argon and traces of olefins and oxygenates. Methane, carbon dioxide and carbon monoxide, and optionally hydrogen, can be recovered from the gas mixture in a very efficient way.

Method for processing a gas mixture

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.

Process for preparing a paraffin product

Process for producing purified synthesis gas from soot-containing synthesis gas having a temperature of at least 5&#xb0; C. above its dew point comprising the steps of (a) cooling the soot-containing synthesis gas to a temperature below its dew point by indirect heat exchange in a shell-tube heat exchanger without removing the condensate formed, thereby forming a synthesis gas/condensate mixture; and (b) contacting the synthesis gas/condensate mixture with a scrubbing liquid to remove the condensate resulting in a purified synthesis gas and used scrubbing liquid, wherein the soot-containing synthesis gas in step (a) is passed through the shell-tube heat exchanger at the tube side.
