A process and apparatus for high temperature combustion in a combustion chamber comprising two opposed porous plates is provided whereby increased combustion temperatures are achievable by means of internal radiant energy recuperation. The high temperature combustion apparatus and process may achieve super-adiabatic combustion temperatures and is especially suitable for applications such as waste disposal and incineration.

Process and apparatus for high temperature combustion

A process and apparatus for production of synthetic hydrocarbon fuels from peat providing wide variation of the composite proportion of liquid-gas output while maintaining high overall carbon conversion to useful fuel. The process and apparatus utilizes three process stages in a single vessel providing functions of drying wet peat, provisions for addition of both wet and dry peat to a hydropyrolysis zone and gasification of the peat char.

A solid adsorption air conditioning apparatus for cooling and heating which is compact in size and particularly adapted to low capacity and which may be at least partially solar powered and air cooled. The apparatus utilizes water vapor as refrigerant working within a hermetically sealed module. The hermetically sealed module has opposing thermally conductive walls which are internally coated with water vapor adsorbent material and thermally insulated from each other. The water vapor working fluid is desorbed from the adsorbent on the interior of a first side by heating while removing heat from the opposing second side causing the working fluid to adsorb in a condenser function at the second side and then applying heat to the second side while removing heat from the first side causing the working fluid to desorb from the second side and adsorb at the first side functioning as an adsorber while the second side is functioning as an evaporator and recycling said thermal condition sequence to provide desired conditioning to an air conditioned space.

Solid adsorption air conditioning apparatus

A process and apparatus for drying air by a continuous atmospheric pressure and low pressure drop system wherein the adsorbent body is a wheel of thin sheets or layers of fibrous material containing about 10 to 90% by weight of a finely divided crystalline molecular sieve material. The process and apparatus is especially useful for drying air for confined areas down to and less than 0.001 lbs. of moisture per pound of air.

A process for air cleaning by the removal of water and one or more undesirable gases such as NO.sub.x, SO.sub.x and CO.sub.2 by a continuous atmospheric pressure and low pressure drop system wherein the adsorbent body is a wheel of thin sheets or layers of fibrous material containing about 10 to 90% by weight of a finely divided crystalline molecular sieve material. The process is especially useful for the removal of NO.sub.2 from confined areas.

A process for producing hydrocarbon liquids in preference to gases from oil shale. The shale is introduced at the top of a reaction chamber which includes an upper oil shale preheat zone having a temperature not more than about 950.degree. F., a hydroretort reaction zone at a temperature of about 850.degree. to about 1250.degree. F. and a lower hydrogen preheat zone to recover heat from spent shale. Solids from the shale are passed downwardly through the chamber so that the shale, and particularly the oil therein, is gradually heated to the reaction temperature over a relatively extended period of at least ten minutes so as to inhibit the formation of a carbon residue. A hydrogen-rich gas, containing hydrogen in excess of stoichiometric amounts needed for the hydroretorting of the oil in the shale, is passed upwardly in the reaction chamber and countercurrent to the shale solids passing downwardly therethrough. A hydroretorting reaction is promoted in the reaction chamber between the oil or organic material in the shale and the hydrogen so as to produce predominately distillable hydrocarbon liquids and a low proportion of low molecular weight paraffinic hydrocarbon gases. The process can be controlled to maximize production of aliphatic and alicyclic hydrocarbon liquids which may be utilized for wide variety of purposes including gasificaton for the production of synthetic pipeline-quality gas from oil shale.

Process for production of hydrocarbon liquid from oil shale

Improved metallic heat exchange apparatus particularly useful in a wheel-like form as a sensible heat exchange wheel in an environmental control apparatus. The heat exchange apparatus is constructed of multiple layers of metallic 'honeycomb', with the apertures of the honeycomb layers axially parallel and offset with respect to each other. The multiple layers provide thermal discontinuities so that the face to face temperature gradient of the heat exchanger is continuous. The heat exchange apparatus of this invention is fireproof, a serious deficiency in prior art wax-coated sensible heat exchange wheels used in environmental control apparatus.
