    摘要: A process for converting solid waste into a synthesis suitable for producing liquid fuel, comprising (a) partially oxidizing and combusting solid waste material in a closed combustion zone at a temperature of 800.degree.-1000.degree. C. and at a pressure below ambient to produce combustion gases by introducing into the combustion zone a gaseous oxidant comprising oxygen having a purity of at least 95% by volume and carbon dioxide in an oxygen to carbon dioxide ratio, by volume, of about 50:50, (b) conducting the combustion gases, oxygen and carbon dioxide through the solid waste material; (c) withdrawing a producer gas comprising the combustion gases and any unreacted oxygen and carbon dioxide; (d) removing particulate matter from the producer gas; (e) separating carbon dioxide from the producer gas and recycling a portion of the separated carbon dioxide to the combustion zone; (f) separating the less volatile, condensable components of the carbon dioxide-free producer gas, from the more volatile, non-condensable synthesis gas components thereof, and (g) compressing the producer gas at some time prior to the completion step (e). In a preferred embodiment, the more volatile components and at least a portion of the separated carbon dioxide from step (e) are admixed and the resulting admixed gas mixture is reacted to form methanol. Preferably, the less volatile components are converted by chemical reaction to hydrogen and the hydrogen is recycled into admixture with the producer gas at some time prior to the commencement of step (e).

    摘要: Plant material containing hemicellulose and lignin is prehydrolyzed in the presence of steam and the vapors of a dilute acid solution having a pH of 1.5-3.5 at a temperature of 105.degree. C to 135.degree. C for 7-20 minutes to hydrolyze the hemicellulose into pentoses and hexoses and to leave a fibrous material and a liquid, said liquid containing said pentoses and hexoses. The liquid is separated from the fibrous material, and the pentoses and hexoses are recovered from the liquid. The fibrous material is digested with white liquor at a temperature of 105.degree. C to 135.degree. C.

    摘要: A system for the collection of solar radiation and the recovery of thermal energy therefrom includes solar radiation receiver means at or near the focus of a solar radiation concentrating means for absorbing the solar radiation, converting it to thermal energy and transferring the thermal energy to ambient air drawn over the receiver means and, thereafter, directed to an energy reclamation unit. In the energy reclamation unit the heated ambient air deposits a portion of its thermal energy in regenerators, from which it is recovered by a compressed air stream, and transfers a portion of its thermal energy to a power fluid. The thermal energy of the ambient air is reclaimed from the compressed air stream and the power fluid as shaft work in expansion turbines. In a preferred embodiment, the solar radiation receiver means comprises a high temperature resistant, porous, convex enclosure having inner and outer porous, convex surfaces arranged in spaced apart nested relationship for defining therebetween an annular space which is randomly filled with a plurality of close to ideal black body solar radiation absorbing elements.
