Experimental Study on Direct and Catalytic Pyrolysis of Chlorella Vulgaris Powders
摘要
Abstract
The pyrolysis characteristics of chlorella vulgaris powders were investigated by thermogravimetry technology.Using HZSM-5 zeolite and HY zeolite as catalysts,a comparison on chemical composition of bio-oil from chlorella vulgaris powders by direct and catalytic pyrolysis approaches was presented.The influence of the two kinds of catalysts on catalytic pyrolysis was explored.The results show that the pyrolysis temperature of chlorella vulgaris powders ranges from 160 to 600 ℃.The contents of hexadecanoic acid and nitrogenous compounds are greatly decreased by catalytic pyrolysis ofchlorella vulgaris powders with HZSM-5 zeolite.The amount of hydrocarbons is increased,including plentiful aromatic hydrocarbons such as toluene and xylenes.The content of hexadecanoic acid is reduced by catalytic pyrolysis of chlorella vulgaris powders with HY zeolite,but the content of nitrogenous compounds is greatly increased.The bio-oil contains abundant polycyclic aromatic hydrocarbon,especially naphthalene.HZSM-5 zeolite is highly active in deoxygenation and aromatization.Due to the poor shape-selectivity of HY zeolite,the contents of polycyclic aromatic hydrocarbon and nitrogenous compounds are increased.关键词
