The gases released were condensed using water condenser and later sepa-
rated into different fractions. However, in the catalytic degradation process,
about 100 g of LDPE were sandwiched between 10 g of CaCO 3 catalyst
layers with catalyst/LDPE ratio of 0.2. Further, the reactor was heated at
a temperature of 420°C for duration of 80 min. The evaporated reaction
products were condensed and collected later, and finally, it is subjected to
fractional distillation to separate different boiling point hydrocarbon frac-
tions obtained from catalytic pyrolysis of waste LDPE. Fig. 11.5 shows the
arrangement of raw material and LDPE. Calcium carbonate is used as cat-
alyst for the catalytic pyrolysis process and is most economical and easily
available. Physical characterization of oil and fractions obtained are shown
in the Table 11.1.
