Review and Design Overview of Plastic Waste-to-Pyrolysis Oil Conversion with Implications on the Energy Transition

Table 6

Thermal depolymerization vs. catalytic depolymerization.

Thermal depolymerization	Catalytic depolymerization
Less liquid fuel produced	More liquid fuel produced
Higher yield of gases and char	Lower yield of gases and char
Generally requires more energy	Less energy required
Gases produced are channeled back to the reactor to boost energy	Catalysts used are very expensive, accounts for 65% of production cost
