Bottom enclosure: A flat plate enclosure of thickness 8 mm was esti-
mated using the equation

f = 13.8 × 10 kgf/cm .
Design of top enclosure: A flange plate head is designed (Fig. 11.2), with
a maximum thickness of 6 mm that is estimated using equation

where, C p = 0.44, D e = B.C.D = 165 mm, P i = 200 psi, f = 2447.32 kgf/cm .
Number of bolt estimation: Number of bolts is estimated to be 8
using equation N = (G i + G o )/2where G i = Inner diameter of gasket =
120 mm, G o = Outer diameter of gasket = 140 mm.
Volume of the reactor: The volume of the shell was found for a
181 mm reactor height and is about 2.05 L.
Heat source: Electric heater made of inconel tubular heater of 2 kW
and 230 V is clamped on the reactor along with glass wool insulation on it
and temperature of above 550°C can be attained (Fig. 11.3).

11.3.1 Production of Fuel Oil
In the present study, low-density polyethylene (LDPE) was used. Further, it

is cleaned, dried and shredded (5–10 mm ), and used as a feed stock for the
degradation process. Powdered CaCO 3 (99.8% pure, particle size 100 μm)
was used as a basic catalyst for the catalytic degradation reaction. The deg-
radation of LDPE was carried out in a customized batch reactor, with al-
lowable pressure of 70 bar (7 MPa). The reactor was heated approximately at
