A cyclone wasdesigned and constructed for the downstream of the reactor toseparate the produced char particles from the gas phase. Separatedchar particles were stored in a char collector. The upper section of thecyclone was a cylinder with the dimensions of 3.5 and 2.54 cm indiameter and height, respectively. The height of the conical section ofthe cyclone was 5.08 cm, and the inlet of the cyclone was rectangularin shape, with dimension of 1.27 cm in height and 0.55 cm in width.The reactor and cyclone were sized to provide a residence time ofless than 1 s for the gas phase before it entered the first condenser. Hotchar as a byproduct of pyrolysis is known as an active catalyst. Theorganic vapors in the gas stream crack to secondary char, water, andnon-condensable gases.28Therefore, it is necessary to minimize itscontact with the pyrolysis vapor products by removing it rapidly.Although the smaller cyclone size benefits from a lower residence timefor the vapor phase, it leads to a higher pressure drop (ΔP), requiringan optimum design for the cyclone. To avoid early condensation in thecyclone and in the char collector and retain the temperature of thevapor above 400 °C, the entire line from the reactor to the condenserswas covered with heating tape and isolated using isolation materials
