FLUIDIZED BED CATALYTIC CRACKING APPARATUS WITH VERTICAL CYCLONE

摘要

FIELD: chemical industry. SUBSTANCE: apparatus has cyclone-type ascending flow separator positioned outside reaction chamber. Separated catalyst is delivered from separator to desorber and separated vapors are delivered into gas collector, with desorber and gas collector being positioned within reaction chamber. Apparatus is further provided with device for discharging desorbed gas from catalyst desorber and for supplying it through cyclone-type ascending flow separator into gas collector. Constant pressure is maintained in separator relative to pressure in reaction chamber. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation.
