A downer reactor was developed at ICFAR to maximize the liquid yield of pyrolysis in the conversion of biomass and heavy oil feedstock. An experimental study using hot wire anemometers was performed to measure the residence time distribution of the gas phase in the reactor and around the gas-solids separator. Some gas backmixing was observed around the gas-solids separator, which decreased with increasing distance between the separator and the gas outlet.
