To improve the knowledge about pyrolysis behavior of reed black liquor (RBL), reed black liquor particles (RBLP) pyrolysis experiments were performed in nitrogen atmosphere at 530, 580, 630, 680, 730 and 780 degrees C in fluidized bed at atmospheric pressure. The effects of bed temperature on yields of pyrolysis product, gaseous product characteristics, carbon and hydrogen conversions, NOx and SO2 emissions, and the micro-morphology of RBLP char were investigated. The results showed that the main components of the gaseous products were CO, CH4, CO2 and H-2. The contents (% by volume) of H-2 and CO were increased with the increase of bed temperature, but CH4 and CO2 had an opposite trend. In addition, the combustible gases concentration increased with temperature increasing, which was from an initial 64.03% (at 530 degrees C) increase to 77.36% (at 780 degrees C). At last, the great impact of pyrolysis temperatures on micro-morphology of RBLP char had been found. (C) 2015 Elsevier Ltd. All rights reserved.
