Utilization of Synthesized Zeolite for Improved Properties of Pyrolytic Oil Derived from Used Tire

Table 2

Standard methods for physical property analysis.

Physical property	Method	Process description
Density	ASTM D1298-12b	Use of a hydrometer placed in a constant temperature bath.
Kinematic viscosity	ASTM D445-15	Use of a calibrated glass viscosity tube submerged in a water bath at 40°C.
Flash point	ASTM D93-15a	Use of the Pensky–Martens closed test cup filled up to its mark with the test sample. The temperature shall be at least 18 °C below the expected flash point for the test sample and the cup.
Pour point	ASTM D97-15	Use of the test jar glass that held the sample. Samples are first heated and then cooled at a specific rate at decrements of 3°C. The temperature 3°C above the point the oil stops moving is noted as the pour point.
Higher heating value	ASTM -E711	Use of the Parr oxygen bomb calorimeter.
Sulphur content	ASTM D7039-15a	Method based on measurement of the specific wavelength from excitation of sulphur, which can accurately measure the concentrations of sulphur from 2 to 500 ppm.
