Lignin, an aromatic constituent of woody biomass, is a potential renewable aromatic feedstock for a sustainable future carbon economy. Lignin is a polymer of phenylpropane units containing three different aromatic ring substitution patterns: p-hydroxyphenyl, guaiacyl and syringyl depending on the wood species. These monomers are linked together through various kinds of ether linkages (C−O) and condensed (C−C) bonds, which leads to a rigid structure for lignin. Pyrolysis of Lignin and Yellow poplar produces bio-oil, which majorly contains high amount of water, acid content, oxygen-derivatives of organic compounds such as ketones esters etc. The aim of this work is consumption of CH4 as source of hydrogen, methyl radicals, which will utilized in the hydrogenation, coupling reactions with oxygenates, phenols present in the bio-oil, and finally removes oxygen and increases the aromatic hydrocarbons in the bio-oil. Due to the wide availability of methane as the main component of natural gas, its use in the pyrolysis as a source of hydrogen is beneficial to produce bio-fuel rich in aromatic benzene monomers from the Lignin and Yellow poplar biomass. |
