Abstract :
As the massive agent in the paper mills, deinking agent was wasted to pollute environment. Therefore, Py-GC/MS was used to analyze the bioenergy resource of deinking agent. After treated with freeze-drying, the comminuted power of deinking agent was pyrolyzed in He atmosphere at 590 square , then the pyrolysis product was analyzed by online linked GC/MS. Relative content of each component was determined by area normalization, and 67 compounds representing 99.96% were identified. The main and abundant constituents were hexadecanoic acid (51.21%), octadecanoic acid (30.58%), carbon dioxide (2.89%), 1-pentadecene (1.76%), octadecanoic acid (1.13%), 1-heptadecene (0.92%), tetradecanoic acid (0.79%), 2-heptanone, 3-hydroxy-3-methyl- (0.65%), 1-tetradecene (0.64%), 1-hexene (0.56%), 1-hexadecene (0.55%), stearic acid, 2-hydroxy-1-methylpropyl ester (0.55%), cyclopropane, ethyl- (0.49%), hexadecanoic acid (0.37%), 1-tridecene (0.34%), and so on. So pyrolysis products of deinking agent could be used to bioenergy, expensive chemicals, and so on.
