Volatile organic compounds characteristics during the ZnXl_2 additives biosolid pyrolysis

摘要

Thsi study selected the biosolid of wasteewater treatment plant of petrochemical industry as the raw material.The biosolid immersed with .5 to 5M of ZnCl_2 solution and pyrolyzed at different temperatures.This research investigated the compositions of volatile organic compounds during the pyrolytic process>Results indicated the benzene-ringed VOCs had the highest concentration in the vicinity of 10 min for 3 M ZnCl_2-immersed biosolid pyrolyzed at 600degC.Dichloromethane was the major component of chlorinated volatile organic compounds.Dimethylsulfide was the major compounds of sulfur organic compounds in the pyrolytic exhaust gas.
