Abstract
Experiments on pyrolysis of Chinese Fugu coal were carried out with a downer reactor, and the effects of temperature and coal feeding rate on product distribution were investigated. It was found that the gas yield increases with increasing temperature, and the yield of tar increases with increasing coal feeding rate. When temperature is 650 °C with coal feeding rate of 12 kg/h, the yield of tar reaches the highest value of 10.29 wt % (dry coal basis). Compared to cocurrent downer reactor, the countercurrent downer reactor favors higher yields of C2 + C3 and tar.
