14    Lignocellulosic Biomass to Liquid Biofuels


          can be obtained from the fractioned major components of hemicellulose
          (5-carbons polymer), cellulose (6-carbons polymer), and lignin (polymer
          of phenol) through the biorefinery process.




          1.6 Conclusion
          The concept of LCB to liquid fuels is really a broad issue for the modern
          age. There is very narrow field in our surroundings, where cellulosic
          materials are used as feedstock of liquid biofuels. The crystallinity of
          cellulose and its association with hemicellulose and lignin are two key
          challenges that prevent the efficient breakdown of cellulose into glucose
          molecules that can be converted to liquid biofuels. This chapter is just
          trying to give an updated research finding about the source, chemistry,
          and biorefinery of this valuable material. Biorefineries may play a vital
          role in tackling climate change by reducing the demand of fossil fuel and
          offering sustainable way to generate renewable biofuels, chemicals, and
          materials. At the same time, LCB-based biorefinery is being popular
          because of its great contribution on bioeconomy.
