摘要： The invention relates to a process for operating a system for the water vapor reforming of a hydrocarbon. The system includes a reactor which is suitable for POX operation as well as for a reforming operation, an evaporator, a hydrogen separating stage, and a catalytic burner device. A first part of the catalytic burner device is in thermal contact with the reforming reactor, and a second part of the burner device is in thermal contact with the evaporator. An air/hydrocarbon intermediate feeding pipe for the reactor and a pressure maintaining valve are provided for changing the reactor between the POX operation and the reforming operation. According to the process, during cold start of the system, a heating operation is carried out during which the reactor is first used in the POX operation at a lower pressure and subsequently is used for the reforming operation and simultaneously the pressure is increased to the normal operating pressure. The invention is particularly useful for the water vapor reforming of methanol for obtaining hydrogen for a fuel-cell-operated motor vehicle.

摘要： A reforming reactor system, suitable in particular for water vapor reforming of methanol, has a reforming reactor in which a reforming catalyst material is situated. A drop catching element is assigned to the inlet side of the reforming reactor, in order to catch drops which may be contained in the gas/vapor mixture, and thus prevent their damaging contact with the catalyst material.

摘要： A method for the autothermal reforming of a hydrocarbon, in particular of diesel, includes introducing a combustible mixture of the hydrocarbon to be reformed and an oxygen-containing medium into a first reaction zone of a reformer, A gas-phase reaction is ignited. After an operating temperature required for the autothermal reforming process is reached, water or a water-containing medium is introduced into the first reaction zone, and the water content is increased until the conditions for the reforming process of the hydrocarbon prevail. The reforming process then takes place predominantly in a second reaction zone.

摘要： In a method for controlling fuel supply to a fuel cell system having at least one fuel cell, the power withdrawal from the fuel cell is performed via a timed switching-on and switching-off of an electric connection between the fuel cell and a consuming device, as a function of the fuel present in the fuel cell. The quantity of fuel is controlled as a function of a pause to switch-on ratio of the timed connection of the fuel cell with the consuming device in such a manner that, based on an actual value of the pause to switch-on ratio, a predefined desired value of the pause to switch-on ratio is set.

摘要： A process for operating a methanol reforming system in which, in the reforming reaction operation, methanol is reformed in a methanol reforming reactor using a methanol reforming catalyst. The reforming reaction operation is interrupted periodically for catalyst reactivation phases during which the methanol reforming catalyst whose catalytic activity decreases in the reforming reaction operation is treated in an activity-regenerating manner. The process may be used in fuel-cell-driven motor vehicles for generating hydrogen for the fuel cells from methanol carried along in the liquid state.
