摘要：

Pyrolysis of reed black liquor was tested in the form of both dried powder in a thermogravimeter connected to a mass spectrometer (TG-MS) and fed droplets (RBLD) in an atmospheric fluidized bed at temperatures of 530-780 degrees C. The effects of temperature were examined to clarify the variations in composition of gaseous products and the microscopic appearance of char. Examination was also performed for the releases of species containing Na, K, and Cl during pyrolysis. The results obtained show that the concentration of combustible components (CH4, H-2, and CO) in pyrolysis gas increased with increasing bed temperature to reach 66.1% at 780 degrees C. There are more Na, K, and Cl releasing into the gaseous product at higher temperatures. The variation in the micromorphology of char from RBLD pyrolysis has been obtained and analyzed.
