Abstract

The quest for new eco-friendly energy resources dates back to three decades not because of the resources are being scarce but because of its capacity to mitigate the unfriendly environmental issues. The fossil fuel resources are formed over thousands of years of biochemical conversion, which is insufficient to feed the ever-growing need for energy usage. Moreover, their contribution to increasing pollution needs to be reduced. As this process is slow, alternate method of rapid fuel generation (thermo-chemical conversion) came into consideration that paves a more promising route in deriving bio-oil from biomass. Liquefaction is such technique of deriving bio-oil from biomass species that ensures high energy efficiency, low tar yield and lower operating temperature. It operates usually between the temperature of 523K and 647K, and pressure of 4 to 22 MPa. This paper particularly highlights the derivation of bio-oil derived from rice straw biomass (UMA paddy straw) from the pyrolytic gas, followed by the computational modelling of fixed-bed combustion reactor using K-epsilon turbulence model displaying temperature gradient, pressure gradient profile and streamlines of fluid flow inside combustion reactor. Furthermore, pyrolysis and liquefaction are promising alternatives for enriched bio-oil production for simplicity compared to other thermochemical conversion processes.
