Method and device 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
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.
1. A device for an accelerated oxidation test of fuels or petroleum products, the device comprising:
a data processing device,
a pressure vessel to hold specimen of the fuels or the petroleum products, the pressure vessel comprising at least one temperature changing device,
wherein the at least one temperature changing device constitutes a part of the bottom of the pressure vessel or the at least one temperature changing device is placed at the bottom of the pressure vessel,
where the internal surface of the pressure vessel at least partially is provided with a surface resistant against at least one of chemical, physical and catalytic effects between the specimen and the pressure vessel, and
where the data processing device is configured for executing a method for an accelerated oxidation test of fuels or petroleum products, the method comprising:
bringing the specimen, which is placed in the pressure vessel, to a predefined temperature above 100° C. using the at least one temperature changing device, and
monitoring the pressure in the pressure vessel and determining the breaking point by a predefined percentage of the drop of pressure with respect to the maximum of the absolute pressure value.
2. The device according to claim 1 , wherein the at least one temperature changing device comprises a heater.
3. The device according to claim 1 , wherein the resistant surface comprises gold.
4. The device according to claim 1 comprising an ultrasonic vibrator.
5. The device according to claim 4 wherein the ultrasonic vibrator is disposed in the specimen.
