- 摘要：
Appts. for synthesis of urea from NH3 and CO2 at 100-250 degrees C and 100-300 kg/cm2 comprises a vertical cylindrical reactor contg. a series of transverse plates. The plates have openings fitted with movable elements acting as non-return valves. The non-return valve action prevents back-circulation of the reaction mixt. rising through the column, this favours the piston-type flow required for the equilibrium dissociation of NH4 carbamate.
