Pyrolysis Oil | SVM 3001 – Viscosity Testing of Pyrolysis Oil
Kinematic viscosity is a key parameter influencing not only the product’s combustion. Anton Paar’s SVM 3001 viscometer offers the perfect solution to determine viscosity and viscosity profiles from one measurement cycle.
Pyrolysis of different waste materials is a procedure that allows to convert them into useful products. Pyrolysis oils can be produced from:
- Wood and agricultural residuals
- Waste tires and other rubber
- Mixed or sorted plastics such as PP, PS, PE
- Oil sludge
Pyrolysis oils are feedstocks to be processed and refined into other products. Depending on their origin, this can be fuel oil such as diesel fuel or jet fuel of different qualities, lubricants, but also heavy fuel oil and asphalt. Especially from waste tire pyrolysis oil, carbon black for the rubber industry can be produced. Another potential application is the direct use of pyrolysis oils as industrial fuel for burners or furnaces e.g. in cement plants or in biomass-to-electricity systems.
Parameters
The most important parameters are viscosity, density, and calorific value. With SVM 3001, these parameters can be determined:
- Kinematic viscosity; typically tested at 40 °C, for some oil types also at 50 °C or at other temperatures as well as changes over temperature and time.
- Density; typically tested at 15 °C
- Calculated Carbon Aromaticity Index (CCAI)
Viscosity is important for injection, atomization and combustion when used as fuel and the correct storage temperature (a too high temperature can change the viscosity especially of bio pyrolysis oils).
CCAI helps to predict ignition properties. Refractive Index (RI) can be of interest as quality parameter to check purity. SVM 3001 with an Abbemat refractometer can determine the RI from one sample filling.
