Effect of Process Parameters on the Production of Pyrolytic Products from Biomass Through Pyrolysis

Lignocellulosic biomass is the prime feedstock for the generation of energy. Pyrolysis is the critical tool for converting biomass into a different phase of energy such as liquid, solid and gas. Though the foremost objective of the pyrolysis of biomass is the extraction of the liquid, other parameters also find application. The liquid fuel gained from the pyrolysis can be used directly for industrial applications or can be upgraded and utilized for engine grade application. The yield and properties of pyrolytic oil or liquid oil varied greatly with the composition of biomass, operating conditions and adopted reactors. In order to achieve the maximum liquid yield, optimization of process constraints becomes imperative. This study addressed and critically appraised the operating constraints such as temperature, heating rates, residence time, sweeping gas, attendance of mineral matter, particle size, the moisture content in biomass and types of reactor. Overall, this study reflects an in-depth overview and analysis of the operating parameters necessary for the generation of liquid fuel or pyrolytic oil.
