In the present research, microwave assisted pyrolysis of biomass feed stocks such as corn cob, corn stover, saw dust and rice straw were carried out at constant microwave experimental conditions. GC-MS and bomb calorimeter analyses were carried out to identify the compounds present in bio-oil and higher heating values (HHV), respectively. Amongst all, corn cob gave the highest bio-oil yield up to 42.1% (wt) with a higher bio-oil HHV of 22.38MJ/kg at the given experimental conditions. GC-MS analysis of corn cob based bio-oil showed the presence of ethyl ether, phenol, aliphatic hydrocarbons, furfural, furan derivatives and acids in major proportions. Higher HHV of bio-oil from corn cob was due to the presence of ethyl ether and 2-bromo-butane with a relative proportion of 15.63% and 4.60%, respectively. Addition of MgCl2 compound as a catalyst during corn cob pyrolysis yielded only in selective formation of furfural compound, and bio-oil yield in this case was found to be similar (40%, wt) to that of pyrolysis of corn cob in absence of catalyst. The results suggested that the corn cob can be used a potential biomass feed stock to produce bio-oil in major quantity, which can be further distilled to produce fuel oils. (c) 2016 Elsevier B.V.
