Biofuels have emerged as a widely used renewable source of energy in the recent years. However, the rising demand for biofuels in developed as well as developing countries has put a lot of pressure on feedstocks such as corn, sorghum, and soy, which are food crops. To ease off this pressure on food crops, scientists around the world are working on methods to convert lignocelluloses from plant waste material into biofuels, instead of utilizing more food crops.

Any types of biomass derived from plant such as cellulose, hemicellulose, and lignin are known as lignocellulosic biomass. It is possible to categorize lignocellulosic biomass into four categories: energy crops, wood residues, agricultural residues and municipal paper waste.

Lignocellulosic biofuels have the potential to provide a large portion of cheap fuel for transportation especially if the available conversion processes are made cost effective. If technological hurdles are overcome, then a wide variety of lignocellulosic biomass can be converted into biofuels.

Taiyou Research focuses on Lignocellulosic Biofuels in its research report Analysis of Lignocellulosic Biofuels.

The report begins with an introduction to the basics of lignocellulosic biofuels. The section on Introduction to Lignocellulosic Biofuels analyzes the potential of lignocellulosic biofuels, the feasibility of using lignocellulosic biofuels to produce fuels, types of biofuels that can be produced from lignocellulosic biofuels, the structure of lignocellulosic biomass, and the conversion process involved in changing biomass to fuels.

The report Analysis of Lignocellulosic Biofuels analyzes the following in the scope of its research:

- Production of biofuels from biomass that has been catalytically processed

- Various feedstocks that used for lignocellulosic biofuels

- The various conversion routes and technologies used in the production of fuels from lignocellulosic biofuels, such as gasification of biomass, conversion of synthesis gas, conversion of syngas, hydrothermal upgrading, and many more.

- The routes closer to achieving a commercial breakthrough such as hydrolysis and fermentation of sugar, gasification, fermentation of synthesis gas, are analyzed.

- Thermal processing of cellulosic biomass and lignin is analyzed through an analysis of the complete process. Technology used, barriers and trends in the process of fast pyrolysis and liquefaction are all analyzed comprehensively.

- Techniques used for petroleum refining that are applied for biofuel production are analyzed, including production of hydrocarbon-based liquid biofuels.

- Catalytic processing of biomass-derived compounds in the liquid phase is analyzed, along with an analysis of feedstocks that are used such as cellulose, lignin, starch, proteins, and plant and animal glycerides.

- Factors affecting the quality of biomass is included along with an analysis of lignocellulosic ethanol.

- The pretreatment process of lignocellulosic biomass to increase the yield of biofuels is analyzed. The methods analyzed include pyrolysis, steam explosion, AFEX, carbon dioxide explosion, among others.

- Projects and pilot plants around the world are analyzed.

- Players driving the industry such as Abengoa, BP Plc, BRI Energy, Iogen, and many others are analyzed, along with a look at their major lignocellulosic biofuel projects.

- The appendix covers generalized information on biofuels, such as requirements for a good fuel, bio-oil fermentation, life cycle assessment of biofuels, and much more.
