Performance evaluation of Pyrolysis system (1-5 kg/h) at different temperature

Abstract

The objective of this work is to perform experimental and theoretical analysis to producebio-oil through Pyrolysis of sawdust and pinewood pellets (8mm) in fixed bed reactor using slow Pyrolysis. The experiments are performed at five different Pyrolysis temperatures 400, 425, 450, 475 and 500 °C at constant heating rate 10 °C/min in selfPyrolysis environment. Bio-oil is found to have distinct properties of being acidic, high water content to be considered as a fossil fuel, but can be used as a replacement for the furnace oil. The characterization of bio-oil carried out like calorific value, viscosity, pH, density, flash point, fire point and water content. The characterization of bio-char and Pyro-gas is also carried out. Bio-char obtained is having higher calorific value similar to bituminous coal and hence can be used for co-generation and synthesis of activated carbon. In the Pyro-gas composition, carbon monoxide (CO), hydrogen (H2) and methane(CH4) combustible gases obtained which can be used for thermal applications.
