Natural polymers of lignocellulosic materials (cellulose, hemicelluloses and lignin) are among the most important renewable raw materials in the carbon economy and renewable energy in the future. Most chemicals produced from petroleum or natural gas can be obtained from lignocellulosic biomass. Diesel and gasoline fuels from crude oil are widely used in modern transportation industries. Biomass can help substitution of these petroleum-derived fuels. Gasification is a chemical process that converts lignocellulose biomass into suitable gaseous fuels or chemicals feedstock. Pyrolysis, partial oxidation and hydrogenation are related processes. Combustion process also converts lignocellulose biomass into gaseous products, but there are some important differences. Pyrolysis-based technologies, such as fast pyrolysis and gasification, are promising methods for converting natural polymers of lignocellulose material into high value-added materials such as biochemicals, biomaterials and biofuels. Better understanding the variables affecting the pyrolysis/gasification of lignocellulose natural polymers develops gasification control systems, overcomes environmental issues and problems and mitigates the structural disadvantages of these two methods. In this paper, a summary of the researches done on the effect of operational variables affecting the pyrolysis and gasification of natural polymers of lignocellulose structures as well as their products is reviewed.
