Pyrolysis of low-rank coal with heat-carrying particles in a downer reactor

A novel co-current downer pyrolyzer was developed that can feed heat-carrying particles (silica sand, particle size, dp,sand=0.116mm) preheated in a fluidized bed separately with coal from the top of the reactor. This allows the high-temperature particles to directly contact coal particles. The infl...
