Naturel polymers of lignocellulose materials (cellulose, hemicelluloses, and lignin) are among the most important and renewable raw materials for future carbon economy and renewable energies. Most chemicals produced from petroleum or natural gas can be produced from biomass. Diesel and gasoline from crude petro-oil are widely used in modern transportation industries. Biomass can help substitute these petro-derived transport fuels. Gasification is a chemical process that converts lignocellulose biomass materials into useful convenient gaseous fuels or chemical feedstock. Pyrolysis, partial oxidation, and hydrogenation are related processes. Combustion also converts lignocellulose biomass materials into product gases, but there are some important differences. Pyrolysis-based technologies, such as fast pyrolysis and gasification, are promising methods for converting natural polymers to high-value added materials such as chemical biomaterials, biomaterials and biofuels. Understanding the variables affecting pyrolysis/gasification of lignocellulose natural polymers, develops gasification control systems, overcomes environmental issues and problems, and mitigates the structural disadvantages of pyrolysis and gasification. In this review paper, a summary of research on the influence of operating variables on pyrolysis and gasification of natural polymers of lignocellulose structures as well as their products is investigated.
