Pyrolysis Properties of Cellulose and Lignins isolated from Different Turkish Biomass: Evolved gas analysis in pyrolysis of biomass and combustion of char via TG-FTIR

Abstract

Abstract Biomass is encouraged as a renewable energy source due to the energy crisis and the increase of greenhouse gases in the environment. Basic energy conversion methods, such as gasification and combustion, start with the devolatilization of organic molecules. In this study, the behavior of agricultural biomass from Turkey that contained various cellulose and lignin fractions was studied during slow pyrolysis and combustion. The pyrolysis of lignin produced the largest gas production, with CO2 constituting up the bulk of the gas mixture. CO is the second-highest-yield gas and is primarily formed from samples of cellulose and lignin. For lignin samples, the pyrolysis operation yielded the maximum amount of char, while the combustion of the lignin chars produced the highest amount of gas yields. On the other hand, lignin samples, particularly almond lignin, have the lowest tar production. One of the most significant issues with gasification is tar production and removal, and biomass rich in lignin would be the best material to use when tar formation must be kept to a minimum.
