Mango peel as source of bioenergy, bio-based chemicals via pyrolysis, thermodynamics and evolved gas analyses

Abstract

Waste biomass is one of the promising feedstocks for bioenergy generation in present era. The aim of present study is to demonstrate Mango peel as a source of bioenergy, bio-based chemical and phenols productions via pyrolysis, thermodynamics and evolved gas analyses. Therefore, samples were characterized through thermogravimetric analyser, Fourier transform infrared spectrometry (FTIR) and pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS). Pyrolysis experiments were carried out at different heating rates i.e. 10, 20 and 30 °Cmin−1 and thermodynamic parameters were calculated using different kinetic models. The apparent activation energy was found in range of 88 kJ mol−1 to 304 kJ mol−1 with all kinetic models. Evolved gaseous analysis was performed though out pyrolysis and between three temperature intervals for qualitative and quantitative analysis of pyrolytic compounds. Similarly, effect of temperature and heating rate on pyrolytic compounds concentrations were also carried out. Release of several chemicals, aromatics compounds and high phenols concentration i.e. 21.01 % via Py/GC-MS confirms its potential for bioenergy, bio-based chemicals productions and anti-oxidant characteristics associated with phenolic compounds.
