The Pyrogenation-Characters of Different Layers of the Castor Stalk

Castor is one kind of excellent woody materials and can be used to make wood based panel instead of the wood materials. To use the castor stalk better, it studies the chemical composition including cellulose, hemicellulose and lignin by high performance liquid chromatograph (HPLC) and the standard of PRC respectively, the pyrogenation-characters by thermo gravimetric analyzer (TGA) and the relationship between chemical composition and the pyrogenation-characters by SAS. The results showed that the chemical composition and pyrogenation-characters are different in different layers of the castor stalk, besides the castor stalk is mainly pyrolysis in second stage (between 170-330°C).
