    摘要： A method and apparatus for recovering heat from solid particles in a fluidized bed reactor, utilize a heat transfer chamber, having heat transfer surfaces disposed therein. Hot solid particles are continuously fed into the heat transfer chamber and gas is introduced into and discharged from the heat transfer chamber. Gas is introduced into the heat transfer chamber for controlling the flow of solid particles therein. The heat transfer chamber is divided into at least one heat transfer zone and at least one solid particle transport zone, by providing more heat transfer surfaces in the heat transfer zones (e.g. 90% or more of the total heat transfer area) than in the solid particle transport zones. The heat transfer is controlled by introducing separately controlled flows of gas into the heat transfer zones and the solid particle transport zones.

    摘要： An apparatus and method are disclosed for the separation and extraction of a waste material into a solid, a liquid, and a gas phase utilizing a rotating drum that is heated by a fluid medium circulating over the exterior surface of the drum in a chamber. The interior of the drum is sealed from the atmosphere and from the chamber. The waste material flows to the interior of the drum where the liquid components are vaporized and the solids are dried. The drum vapor effluent is cooled and the condensable components are condensed and separated. The noncondensable components are used as fuel for heating the heating medium. The dry solids flow from the retort to disposal facilities.

    摘要： A continuous process and system is provided for a petroleum oil in a multi-phase fixed bed catalytic reactor column comprising methods and means for:feeding the oil and a reactant gas at production flow rates above a first bed of porous solid catalyst particles under conversion conditions for cocurrent downward flow therethrough, collecting and withdrawing the treated oil from the first bed and redistributing at least a portion of the treated oil to at least one succeeding catalyst bed while permitting the gaseous phase to flow directly to the succeeding lower catalyst bed, recycling a quantity of treated oil collected below a catalyst bed and reapplying the treated oil at a preceding redistribution zone above the bed from which treated oil is collected, whereby the total of oil production flow rate and recycled treated oil flow rate is maintained at a predetermined minimum sufficient to effect uniform catalyst wetting. This technique is useful for hydrodewaxing of oils over zeolite catalysts.
