An object of the present invention is to provide a new frameless catalytic thermal oxidation device capable of treating concentrations of harmful materials including NOx at a low temperature. Further, another object of the present invention is to provide a frameless catalytic thermal oxidation device capable of minimizing the occurrence of THC and minimizing a risk of accidents and environmental pollution which may occur in maintenance operations. According to the objects, the present invention provides a cartridge-type thermal oxidation device capable of being separated for maintenance, wherein a cartridge internal structure is configured so that the time while the material to be treated stays in a zone with the catalyst is increased, and a member capable of dropping and collecting powder generated by thermal oxidation reaction is configured.

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.

This invention relates to a robotic device 10.1, 10.2 and method for handling catalyst material 106, 206 in a reactor 100 by removing spent catalyst from the reactor and/or loading the reactor with fresh catalyst without an operator having to enter an interior of the reactor which increases operator safety. The robotic device includes a body 12, which is configured to engage a flange 104 of the reactor, and a handling arm which is configured for use both as a cleaning arm 18 and a loading arm 218. The handling arm is connected to the body and is angularly and longitudinally displaceable relative to the body. The handling arm has a segment which is telescopically extendible/retractable relative to the body. When used as a cleaning arm, the arm receives a vacuum line for removing catalyst. When used as a loading arm, a telescopic loading sleeve is connected to the segment.

A loading device for loading pellets into reactor tubes has a modular design, which can be taken apart, moved through a manway, and then reassembled simply by stacking one part on top of another. A reciprocating slide plate and a vibrator work together to meter pellets through the loading device and into the reactor tubes.
