Zero Waste Production Technology Investigating Through Gasification Process and Characterization of Its Byproducts (Biochar and Bio-Oil)

This study presents the demonstration of zero waste production technology investigating experimentally by performing the gasification process of eucalyptus biomass and characteristics of its byproducts such as biochar and bio-oil. The outcomes of gasification process in terms of gas composition, calorific value and cold gas efficiency are determined at the optimal operating conditions. The byproducts (biochar and bio-oil) are examined through Gas Chromatography-Mass Spectrometry (GC–MS) and Fourier Transform-Infrared Radiation (FT-IR) spectroscopy in order to find the compounds as well as functional groups respectively. Finally, the uses of gasification products (syngas, biochar and bio-oil) in various fields are emphasized in detail. The experimental outcomes indicated that the calorific value and cold gas efficiency are observed as 5.558 MJ/m3 and 65.68% respectively at the optimal conditions. The bio-oil contains many valuable compounds but Acetic acid is found to be most in percentage (84.93%) among others. The biochar revealed the presence of important functional groups such as alcohol, carboxylic acid, alkyne, isothiocyanate, aromatic compound, sulfoxide and alkene. The gasification products have found a wide application in different sectors to demonstrate the zero-waste production technology.
