PRODUCTION OF RENEWABLE FUELS FROM BIOMASS THROUGH THERMOCHEMICAL PROCESS

Abstract

ABSTRACT newlineNational energy security, energy sustainability and climate changes are the primary reasons to find alternative, newlinerenewable and reliable resources to fulfill energy demand. In this regard, biomass is an intriguing candidate to newlinesubstitute fossil based liquid fuels. Liquid energy derived from organic material can power our vehicles, newlinediversify our fuel mix and reduce emissions. It drives growth in regional areas and adds value to our worldclass newlineagricultural systems. India is full of unexplored biomass, which could be converted to useful energy newlinesources. Among the different biomass to energy conversion technologies, recently pyrolysis has received newlineincreasing attention because they could convert different varieties of biomass to produce high energy pyrolytic newlineoil in addition to char and gas. The liquid product obtained by the pyrolysis of biomass may also be upgraded newlineto refined fuels, added to petroleum refinery feedstock or may contain chemicals in economical recoverable newlineconcentrations. newlineIn this context, the present work focus on the Thermochemical degradation of three different biomass viz. newlineKaner seed (Thevetia Peruviana), Flax seed (Linum usitatissimum) residue and a protein rich microalgae newline(Arthrospira platensis) in a semi batch reactor to understand the effect of temperature, heating rate and clay newlinecatalyst on the product distribution and composition. Heating rate and temperature has significant effect on the newlineproduct distribution. The yield of condensable fraction is more in case of fast pyrolysis than slow pyrolysis. newlineAmong three biomass, kaner seed pyrolysis produce higher bio oil yield at optimum condition as compared to newlineother two biomass. The maximum yield of bio oil from kaner seed obtained at 600ºC was 81.2 wt% with only newline2.2% aqueous fraction, that of flax seed residue produce 50.66 wt% condensable fraction at a pyrolysis newlinetemperature of 500°C, out of which the amount of bio-oil excluding the aqueous layer was 31wt.% and newlinemicroalgae produce a higher condensable fraction of 55.9wt.% was 500°C out of which
