Definitions
- Industrial gases and in particular relates to a novel process for the removal of carbon sulfides from coke oven gas using a noble metal catalyst and its use.
- Coke oven gas often referred to as coking gas, is produced in coking plants during the dry distillation of hard coal. Typically contains
- Coke oven gas as main components about 55 wt .-% hydrogen, 25 wt .-% methane, 10 wt .-% nitrogen and 5 wt .-% carbon monoxide.
- coke oven gas is basically suitable as a synthesis gas for chemical reactions. Since coal contains a certain amount of sulfur, coking of coal and the like can occur. also carbonyl sulfide and carbon disulfide, which must be removed before further use of coke oven gas, since they act as catalyst poisons in follow-up reactions, for example. Without a removal of
- Hydrogenating hydrogen which can then be separated by conventional methods from the gas mixture.
- the reaction temperature in the examples is above 550 ° C.
- Coke gas sulfur compounds for use in the conversion of sulfur compounds into hydrogen sulfide sulfide cobalt-molybdenum catalysts are catalysts which consist predominantly of molybdenum sulfide and contain the cobalt in sulfidic form as a promoter. By using appropriate catalysts was a reduction in the operating temperature in the
- Coke oven gases which also contain a certain amount of oxygen in addition to sulfur compound. Heating the hydrogen-containing gas in the presence of oxygen can lead to uncontrolled oxyhydrogen gas reactions come through which the reprocessing plant for the coke oven gas can be damaged.
- the gas to be fed to the desulphurisation should therefore be as free as possible of oxygen before it is fed to the desulphurisation device.
- the separation of oxygen from gas mixtures such as coke oven gas is technically relatively complicated and thus costly. For this reason, coke oven gas is used today to a significant extent purely thermal (ie by combustion), but due to the sulfur content

- Carbon disulfide compounds such as COS and CS 2 in combination with water to H 2 S and C0 2 are reacted.
- this method does not reduce a hydrogen-rich gas having a proportion of carbon disulfide compounds and oxygen with a noble metal catalyst.
- the process is also divided into two steps, with oxygen being separated from the gas mixture in the first step.
- a Co-Mo catalyst is used for this step.
- Pt-based catalysts it is stated in this document that they have oxidative properties and therefore oxidize H 2 S, which is present in combination with oxygen, to S0 2 . This leads to subsequent reactions with remaining H 2 S to form sulfur, which can lead to clogging of the device.
- JPS 59-232175 A describes the treatment of coke oven gas containing dienes, oxygen, olefins and sulfur compounds as an impurity.
- Corresponding coke oven gases are reduced in the presence of a palladium-based catalyst on an Al 2 O 3 support to H 2 S, which can then be absorbed on an adsorbent such as ZnO.
- H 2 S a palladium-based catalyst on an Al 2 O 3 support
- COS and CS 2 are not mentioned in this publication for the sulfur compounds.
- the composition has an extremely low sulfur content of 0.01% H 2 S, so it can be assumed that no raw coke oven gas is treated here, but pretreatment steps have taken place, but these are not specified in this document.
- the object of the present invention was therefore to propose a method by which the cost of removal of elemental oxygen in industrial gases can be reduced, and at the same time the most quantitative conversion of carbon sulfides present in the gas, and optionally also present organic sulfur compounds (eg. As thiophenes or mercaptans), ensured in hydrogen sulfide, if possible at lower compared to the prior art temperatures. Furthermore, the object of the present invention was to propose a method in which the least possible energy for heating the

- the catalysts could also be fed with oxygen-containing gas mixtures without dangerous mixtures of oxygen and hydrogen being observed in the product. Instead, it has been observed that the oxygen is reacted with hydrogen under the action of the catalyst with hydrogen, so that contained in the reactor-containing from the catalyst-containing gas mixture was only a very small proportion of oxygen ( ⁇ 0.01 vol.%).
- the catalytic conversion of oxygen and hydrogen is also associated with the advantage that the catalyst and the gas mixture is heated by the waste heat of the oxyhydrogen gas reaction, so that an external heating of the catalyst (after it has reached its optimum operating temperature) is no longer required.
- the hot exhaust gas can be used via a heat exchanger to heat the gas flow for the catalyst-containing reactor, resulting in a further energy savings. Therefore, in the present invention, the hydrogen-rich gas preferably contains a proportion of oxygen.

It is particularly preferred if the oxygen contained in the gas is substantially, i. at least 80% by volume, preferably at least 90% by volume and more preferably at least 95% by volume, based on the total volume of oxygen in the gas mixture, is simultaneously converted to water with the reduction of the sulfur-carbon compounds.
- the catalytic conversion of the sulfur-carbon compounds expediently takes place at a temperature of at least 150.degree. C. and preferably at least 200.degree. On the other hand, it is within the scope of the present
- Invention preferably, when the catalytic conversion of the sulfur-carbon compounds at not more than 270 ° C, preferably at most 250 ° C and particularly preferably at most 230 ° C takes place.

- thermal energy is released as part of the reaction of oxygen in the gas mixture with hydrogen. It is therefore possible and preferred if the amount of oxygen in the hydrogen-rich gas is adjusted so that the energy released from the reaction is sufficient to keep the temperature at the desired level.
- the Amount of oxygen in the reaction mixture can be increased by the addition of oxygen, if appropriate.
- the reaction of the catalyst with the sulfur-carbon compounds in the hydrogen-rich gas may be incomplete, so that the gas resulting from the reaction has a content of sulfur-carbon compounds resulting in the further use of the gas makes a negative impression. It may therefore be useful if the catalytic conversion is followed by a stage in which still present in the gas mixtures sulfur-carbon compounds with a
