The invention relates to a device for the, (in particular continuous), oxidation of particulates from the exhaust gases of diesel motors. Said device consists of an open-pored body as a particle filter, on whose surface an oxidation catalyst is finely dispersed. The device is characterized in that from an exhaust gas temperature as low as 150&#xb0; C., the catalyst causes the oxidation of particulates attached to the filter using the residual oxygen of the exhaust gas, thus keeping the filter body continuously free of particulates during almost all the operating conditions of the motor.

In an electrically heated catalytic converter including a heater consisting of a structure having an open porosity so as to permit fluid to flow therethrough, a heterogeneous catalyst is disposed within the heater structure. The heater structure, which includes the catalyst, is capable of accommodating sufficient electrical energy to provide the activation energy required for a particular catalytic reaction to be performed by the catalytic converter.

The invention relates to a method and a device for separating a gas component in a gas mixture by freezing. The gas component to be separated has the lower vapor pressure when compared with the other gas components in the gas mixture. A working temperature is chosen at which the gas components to be separated freezes out almost completely. The partial pressure of the other gas components at working temperature is kept lower than the vapor temperature of the other gas components at working temperature. Once the components to be separated have been frozen out, the other gases are evacuated. The device comprises at least two cooling tanks. Means are provided to alternately feed the gas mixture to the cooling tanks so that a predetermined partial pressure arises in each tank.
