Production of Diesel-Like Fuel and Other Value-Added Chemicals from Pyrolysis of Animal Fat

Pyrolysis of lard was performed in a fixed-bed reactor to produce a diesel-like fuel. Lard was fed into the reactor at 5 g/h using N2 (3 × 10-5−7 × 10-5 m3/min) as carrier gas. The liquid product obtained at a temperature of 600 °C, carrier gas flow rate of 5 × 10-5 m3/min, and quartz packing particle size of 0.7−1.4 mm has a cetane index of 46, specific gravity of 0.86, and a higher heating value of 40 MJ/kg. This study shows that there is a potential for producing diesel-like liquid from pyrolysis of lard. It also identifies the pyrolysis of animal fats as a source of high-calorific-value (68−165 MJ/m3) gaseous fuel.
