Abstract:
A new method for design and scale-up of photocatalytic and thermocatalytic processes is disclosed. The method is based on optimizing photoprocess energetics by decoupling of the process energy efficiency from the DRE for target contaminants. The technique is applicable to photo-thermocatalytic reactor design and scale-up. At low irradiance levels, the method is based on the implementation of low pressure drop biopolymeric and synthetic polymeric support for titanium dioxide and other band-gap media. At high irradiance levels, the method utilizes multifunctional metal oxide aerogels and other media within a novel rotating fluidized particle bed reactor.
Abstract:
A new apparatus for design and scale-up of photocatalytic and thermocatalytic processes is disclosed. The apparatus is based on optimizing photoprocess energetics by decoupling of the process energy efficiency from the DRE for target contaminants and is applicable to both low- and high-flux photoreactor design and scale-up. The low-flux apparatus is based on the implementation of natural biopolymeric and other low-pressure drop media support for titanium dioxide and other band-gap photocatalysts and is further based on the implementation of multifunctional metal oxide aerogels and other media in conjunction with a novel rotating fluidized particle bed reactor.
Abstract:
A restaurant emissions abatement system is disclosed which employs a rotary heat regenerative thermal or catalytic oxidizer. Thus, heat which normally would be exhausted into the atmosphere, is recovered by being transferred to incoming unoxidized restaurant emissions. The rotary oxidizers may be of a variety of designs including orientations which allow for perpendicular or axial flow of the emissions stream through the rotary oxidizer relative to the axis of rotation. The rotary design of the oxidizers also provides an advantage of permitting in-situ cleaning of the oxidizer (i.e., not having to remove oxidizer from abatement system) by simply lowering the speed of the oxidizer's rotation or stopping rotation altogether to permit hot gases to thoroughly oxidize accumulations of such contaminants as greases and fats.
Abstract:
Used oil is treated in a reactor to remove contaminants. The reactor comprises a rotating vessel forming an internal reaction chamber. The vessel is housed within a heating chamber. The inside of the vessel is indirectly heated by conduction through the vessel walls. The reaction chamber contains a permanently resident charge of non-ablating, granular coarse solids. Within the reaction chamber, the oil is vaporized and pyrolyzed, producing a hydrocarbon vapour. Coke is formed as a byproduct. Contaminants, such as metals and halides, become associated with the coke. The coarse solids scour and comminute the coke to form fine solids. The fine solids are separated within the reaction chamber from the coarse solids and are removed from the vessel through a pipe located at the axis of the vessel. The hydrocarbon vapours are also removed from the vessel through the axial pipe, as a separate stream. Residual fine solids are separated in a cyclone from the vapour stream. The cleaned vapour stream is then condensed to produce a substantially contaminant-free product oil. The contaminant-rich solids are collected for disposal.

Abstract:
An apparatus for treating process material includes a vessel into which process material can be introduced, an arrangement for introducing steam into the interior of the vessel to heat and impart moisture to process material in the vessel, and several fluid transport conduits extending helically through the vessel for conveying heated fluid through the vessel between opposite ends of the vessel in order to raise the temperature and pressure within the vessel to treat the material while also allowing the moisture content of the process material to be reduced. The fluid transport conduits are also configured to contact the process material and assist in treating and densifying the material. The vessel can also be adapted to be pivoted so that the forward end of the vessel can be selectively positioned above and below a horizontal position. The vessel can also be interconnected with one or more similarly configured vessels to define a system for treating process material. The system can include an arrangement that allows steam and heat from a hot vessel to be conveyed to a cold vessel. A method for treating process material can include introducing process material into two different vessels, raising the temperature within one of the vessels through the introduction of steam to heat the material in the vessel, and reducing the temperature in the one vessel while also increasing the temperature in the other vessel by venting the interior of the one vessel to the interior of the other vessel.

Abstract:
The method of separating impurities from an aqueous solution by means of rotating tile aqueous solution at high speeds until a high pressure and a high temperature is reached. At that time the impurities are separated from the solution. The aqueous solution is kept at high temperatures and pressures until the impurities are separated from the liquid. Preferably, a device providing a centrifugal force, such as a centrifuge, is used to achieve the high temperatures and pressures which should preferably be no lower than 705.4.degree. F. and 3,208 psi, respectively.
Abstract:
Granular silicon dioxide is placed in a treatment chamber which is heated to a temperature ranging from 700.degree. to 1300.degree. C. The chamber is then rotated for a prescribed period of time to mix the grains while a gaseous atmosphere of chlorine and/or hydrogen chloride is passed through the treatment chamber. The mixing period is followed by a resting period which is at least ten times longer than the mixing time. During the resting period the grains are exposed to a constant electric field having a strength of 600 to 1350 V/cm applied across the chamber. The foregoing cycle is repeated several times. For working the process a device is used which includes a quartz glass rotary tube into which hollow silicon carbide electrodes extend.
