The fuel processor system of the invention generates hydrogen from a hydrocarbon compound or from mixtures of hydrocarbon compounds for generating electric energy and heat by way of a combustion path, along which the generated hydrogen is passed for combustion. Included in the combustion path is at least one fuel cell for generating electric energy. The system further includes a first heat exchanger and a second heat exchanger, which, on the one hand, are series included in the combustion path downstream of the fuel cell. The first heat exchanger exchanges heat between the combustion path and a first heating circuit which includes the fuel cell. The second heat exchanger exchanges heat between the combustion path and a second heating circuit which includes the fuel processor. The generated hydrogen undergoes combustion where the fuel cell assists in generating electric energy and, optionally, the fuel processor assists in generating heat.

Fuel cell system for generating electric energy and heat

The invention is directed to a process for the recovery of sulphur from a hydrogen sulphide containing gas, which process comprises; i) oxidizing part of the hydrogen sulphide in a gaseous stream with oxygen or an oxygen containing gas in an oxidation stage to sulphur dioxide; ii) reacting the product gas of this oxidation stage in at least two catalytic stages, in accordance with the Claus equation: 2 H S&plus;SO &rarr;2 H O&plus;3/n S ; iii) catalytically reducing SO in the gas leaving the last of said at least two catalytic stages, wherein the catalytic reduction takes place in a catalyst bed downstream from the last Claus catalytic stage.
