Abstract

A reactor for accelerating heterogeneous reactions and affording an increased yield rate per unit of time and space comprises a cylindrical reactor tube containing in its interior a piston having relatively flat profiling in its skirt in the form of annular ribs and grooves therebetween, inlet conduits leading into the interior of the reaction tube through the bottom clousre thereof, which may also be introduced from above and extend axially through the piston, an outlet tube is provided in the region of the top closure of the reaction tube, the piston is being connected via a piston rod with a vibrator imparting axial oscillatory movement of the piston, these oscillations generating turbulences in the annular piston grooves which effect a thorough mixing of the reaction participants without causing any noteworthy re-mixing of the resulting reaction products with the starting components.
