A method of enhancing yield and transfer rate of a packed bed in a reactor chamber of a vessel includes steps of applying acoustic energy to the packed bed, measuring impedance of the packed bed deriving a natural resonance frequency of the packed bed from the measured impedance and applying the acoustic energy to the packed bed at the derived natural resonance frequency of the packed bed.

An apparatus for enhancing a yield and a transfer rate of a packed bed includes a packed bed, a vessel having a reaction chamber, a support frame and acoustic attenuator for holding the packed bed in the reaction chamber, at least one acoustic transducer adapted to transmit acoustic energy into the packed bed and an acoustic generator. The acoustic generator has impedance matching functionality.

Mechanical stirred bed reactors that incorporate a screen are described. Methods of using such reactors to process perfluoropolymers to form perfluorinated olefin monomers are also described. The reactors and methods may be used to upcycle filled perfluorinated materials.

A method of carrying out the dehydrogenation of lower alkanes in a fixed-bed reactor containing a catalyst bed, the catalyst bed comprising (i) catalyst particles supporting a catalyst effective to promote said dehydrogenation and (ii) engineered inert diluent particles, where the method comprises passing the lower alkane in gaseous form through the catalyst bed, wherein the engineered inert diluent particles have a cross-sectional shape having two opposing convex edges joined by and intersecting two opposing concave edges, and a plurality of holes between said edges penetrating through the particle.

Described herein is a carbon capture system and methods for improving carbon capture through the introduction of sonic transducers within packed beds in the absorber. The system of sonic energy applied to a packed bed can improve yield or transfer rate in systems using a two phase reaction, such as in general absorption systems, distillation systems, or stripping systems.
