[0832] r-pyrolysis oil example 1-4
[0833]Table 1 shows the composition of the r-pyrolysis oil samples by gas chromatographic analysis. The r-pyrolysis oil samples were prepared from waste high and low density polyethylene, polypropylene and polystyrene materials. Sample 4 was a laboratory distilled sample in which hydrocarbons greater than C21 were removed. The boiling point curves of these materials are shown in Figure 13-16 middle.

[0839] r-pyrolysis oil example-5-10
[0840] Six r-pyrolysis oil compositions were prepared by distilling r-pyrolysis oil samples. They were prepared by processing the material according to the procedure described below.
example 5
[0841] Example 5. r-Pyrolysis oil boils at least 90% at 350°C, 50% boils between 95°C and 200°C, and at least 10% boils at 60°C.
[0842] A 250 g sample of the r-pyrolysis oil from Example 3 was distilled through a 30-tray glass Oldershaw column equipped with a glycol cooled condenser, a thermowell containing a thermometer and a magnet operated reflux regulated by an electronic timer controller. Batch distillation was carried out at a reflux ratio of 1:1 at atmospheric pressure. Collect liquid fractions every 20mL, record overhead temperature and mass to build Figure 17 Boiling curve shown. The distillation was repeated until about 635 g of material had been collected.
example 6
[0843] Example 6. r-pyrolysis oil with at least 90% boiling at 150°C, 50% boiling between 80°C and 145°C, and at least 10% boiling at 60°C.
[0844] A 150 g sample of the r-pyrolysis oil from Example 3 was distilled through a 30-tray glass Oldershaw column equipped with a glycol cooled condenser, a thermowell containing a thermometer and a magnet operated reflux regulated by an electronic timer controller. Batch distillation was carried out at a reflux ratio of 1:1 at atmospheric pressure. Collect liquid fractions every 20mL, record overhead temperature and mass to build Figure 18 Boiling curve shown. The distillation was repeated until about 200 g of material had been collected.
