              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.
