Abstract
Lignocellulosic biomass is the most abundant renewable resource existing, and presently it is considered as a promising feedstock for the synthesis of green chemicals and biofuels for reducing transportation emissions and dependence on fossil fuels.
In this research, a TCR (thermo-catalytic reforming) reactor is used to transform lignocellulosic biomass into high quality bio-oils, biochar and syngas.
Sugarcane bagasse (SB) and oat hulls (OH) were processed in the TCR (2 kg/h) at 450 ºC in the intermediate pyrolysis reactor (kept constant) and varying reforming temperature between 500-700 ºC. This paper studies the conversion potential of SB and OH into sustainable bioproducts at different reforming temperatures.
TCR oils contained the highest calorific value of 34.9 MJ/kg from SB and 35.0 MJ/kg from OH at 700 ºC which makes the bio-oil suitable to be applied as fuel for engines when compared to bio-oils produced from other pyrolysis technologies.
SB and OH pyrolysis gas at 700 ºC contained higher H2 yield 30.9 vol% and 31.6 vol%, respectively. The highest gas caloric values of SB and OH were 18.4 MJ/kg and 18.8 MJ/kg at the same reforming temperatures, respectively. Overall, the TCR results of SB and OH are promising for waste conversion into sustainable fuels.
