  • Patent number: 8066960
    Abstract: A device and a method for an accelerated oxidation test of fuels or petroleum products, as well as a computer program for controlling such a device, and a corresponding computer readable storage medium, which are applicable, in particular, for the simulation of the aging of fuels or petroleum products. A device for an accelerated oxidation test of fuels or petroleum products is proposed, whereby the device comprises of a pressure vessel (1) to hold specimen (2) of fuels or petroleum products, and the pressure vessel (1) contains at least one device to change the temperature. A corresponding method provides that a specimen (2) of fuel or petroleum product is placed in a pressure vessel (1), the specimen is brought to a predefined temperature above 100° C. by at least one device to change the temperature, which is placed in the pressure vessel (1) and/or in the specimen (2), and the absolute pressure value is monitored so as to determine the oxidation.
