A plant for the automatic production of baked goods using a dough strand has a kneading device to knead dough from prepared starting products. An extruder is used to extrude the dough to form the dough strand. A portioning device is used to divide the dough strand into dough strand portions of a predetermined weight. A post-preparation device is used to finish the baked goods from the dough strand portions. The post-preparation includes the supplying of the dough strand portions to associated receivers in at least one transporting mould, fermenting the dough strand portions in the transporting mould and baking the fermented dough strand portions. The result is a production plant with an increased throughput in the production of baked goods and simultaneously a plant outlay which is as low a possible.

In a system and method for the reduction of nitrogen oxides in the exhaust of an internal combustion engine, the exhaust line of the internal combustion engine contains a DeNOx catalytic converter, in which the nitrogen oxides are reduced by means of hydrogen that is produced on-board the vehicle. The DeNOx catalytic converter is incorporated into a temperature-controlled heat exchanger, allowing the DeNOx catalytic converter to be operated within a desired temperature range, thereby improving the level of conversion.

Rapid response to a fuel cell system of the type including a reformer (32) in response to a change in load is achieved in a system that includes a fuel tank (24), a water tank (20) and a source (42) of a fluid at an elevated temperature. A heat exchanger (28) is provided for vaporizing fuel and water and delivering the resulting vapor to the system reformer (32) and includes an inlet (64) and an outlet (66) for the fluid. It includes a plurality of fluid flow paths (100), (102), (104) extending between the inlet (64) and outlet (66) as well as a fuel inlet (56) and a fuel outlet (58) spaced therefrom. The fuel inlet (56) and outlet (58) are connected by a plurality of fuel flow paths (52) that are in heat exchange relation with the fluid flow paths (100), (102), (104) and the fuel water inlet (56) is located adjacent the upstream ends of the fluid flow paths (100), (102), (104).

A system to supply hydrogen-rich fuel to an internal combustion engine, whereby a hydrogen-rich gas is produced from a liquid raw fuel by a hydrogen generator. The exhaust line of the internal combustion engine contains an exhaust purification system, such as a DeNOx catalytic converter, which is at least temporarily supplied with hydrogen-rich gas through a bypass line. In addition, the exhaust line is in thermal contact with the hydrogen generator in order to recover thermal energy.

In a method and apparatus for selective catalytic oxidation of carbon monoxide, the gas mixture and an additionally added oxidizing gas are conducted through a reactor containing the catalyst. Oxidizing gas is added at several points along the mixed gas flow path with a controlled or regulated through flow volume. The mixed gas stream is cooled passively by static mixing structures located in the inlet area of the CO-oxidation reactor. By controlling exothermal CO oxidation along the reactor path, a very variable process guidance is provided, that can be adjusted to individual situations.

This invention relates to a process and an apparatus for the catalytic water vapor reforming of methanol. The reforming process is carried out in two stages. The methanol is incompletely reacted in the first stage in a heat-transfer-optimized process with a high specific catalyst load. In a reaction-optimized second stage, while the specific catalyst load is lower, a further reaction is carried out which completes the methanol reaction. In addition, a tube bundle reactor is disclosed in which the first, heat-transfer-optimized stage takes place in reaction tubes which, for constructing heat transfer medium ducts, are each surrounded by a concentric outer tube, while the second, reaction-optimized stage is carried out after the return of the reform gas in the housing. The reaction tubes as well as the area between the outer tubes are filled with catalyst material.

A fuel cell vehicle comprises an electric drive system and a fuel cell system for providing electric energy for the drive system. According to the invention, the electric drive system is set up for regenerating braking energy, and devices are provided for the direct utilization of the regenerated braking energy in at least one energy-consuming component of the fuel cell system. This direct braking energy utilization in the fuel cell system increases the degree of energy utilization without the requirement of a separate intermediate energy storage device for the intermediate storing of regenerated braking energy.
