Pyrolysis of Garden Waste: Comparative Study of Leucaena leucocephala (Subabul Leaves) and Azadirachta indica (Neem Leaves) Wastes
Pyrolysis is one of the most promising thermal decomposition technologies. Pyrolysis converts biomass materials into bio-oil, biochar, and gases in the absence of oxygen. In the present study, pyrolysis studies on Leucaena leucocephala (Subabul leaves) and Azadirachta indica (Neem leaves) were carried out in a fixed bed reactor at different reaction time of 2 h and 3 h at a reaction temperature of 650 °C using Liquified Petroleum Gas (LPG) and the optimum results were obtained with 3 h of reaction time. The maximum yield of biochar is 8 wt%, bio-oil is 19 wt%, and gas is 3 wt% for L. leucocephala and in case of A. indica, the maximum yield of biochar is 76 wt%, bio-oil is 21 wt%, and gas is 3 wt% were observed respectively. The bio-oil contents were mainly composed of oxygenated hydrocarbons.
