The purpose of this work is studying of kinetics of hydrolysis lignin pyrolysis in the presence of inorganic salts, representatives of classes of alkali and alkaline earth metal halides (NaCl, KCl, KBr, CaCI2, BaCl2 2H20) and Lewis acids (AlCI3 6H20, FeCl3 6H20, CuBr2, ZnCI2 1,5H20. NiCl2 6H20, SnCI2 2H20) using TG-DSC. Activity of these catalysts was estimated by temperature of the beginning of pyrolysis, charcoal yield and kinetic parameters, such as energy of activation and reaction order. Determining the influence of the used catalysts on the qualitative composition of the pyrolysis products was performed by HPLC-MS.
