摘要： Aluminum alkoxides are prepared by the reaction of impure aluminum and monohydric alcohols in a process wherein impure metallic aluminum particles are continuously fed at a metered rate into a stoichiometric excess of alcohol. The novel apparatus disclosed permits the continuous introduction of the aluminum particles into the reactor and removal of non-reactive impurities through columns of ambient temperature alcohol which avoids contact of atmospheric oxygen with the reaction products.

摘要： A continuous process for removal of ammoniacal nitrogen from water is disclosed. This process is useful for maintaining water quality in aquaculture operations, e.g., fish hatcheries and the like. A particulate stream of zeolitic ion exchange material is circulated continuously through an exchanger and a regenerator. An aqueous process stream containing ammoniacal nitrogen, e.g., ammonia, is passed through the exchanger in continuous counter current liquid-solid contact with a stream of particulate, ammoniacal nitrogen-sorbing zeolitic ion exchange material of natural or synthetic origin. A treated liquid water stream having a reduced ammoniacal nitrogen content exits from the exchanger, as does a stream of ammoniacal nitrogen-enriched particulate zeolitic ion exchange material. The latter stream is regenerated in the regenerator at a temperature of about 350.degree. C. to about 650.degree. C. while an oxygen-containing gas stream, e.g., air, is passed in continuous counter current gas-solid contact therewith. Gases emanating from the regenerator are used to preheat the ammoniacal-nitrogen enriched particulate material that enters the regenerator. The regenerated stream of particulate, ammoniacal nitrogen-sorbing zeolitic ion exchange material is recycled to the exchanger.

摘要： High purity alpha-alumina bodies useful as catalyst supports are made by peptizing boehmite alumina in an acidic mixture containing fluoride anions, extruding the peptized alumina into shaped bodies and drying and calcining the bodies. The alpha-alumina bodies are characterized by a narrow pore-size distribution, having 85 percent of the total pore volume comprising pores of a diameter of from 10,000 to 200,000 Angstroms and by a surface area of less than one square meter per gram.

摘要： A method and a system for enriching the oxygen content of a body water having a relatively low oxygen content are disclosed. The method contemplates providing, in a pipeline communicating with the body of water, a pressurized, flowing aqueous liquid stream that is at a pressure greater than ambient and supersaturated with respective to the dissolved oxygen concentration thereof. The liquid stream is maintained substantially free of bubbles which grow in size under conditions existing in the body of water. The flow rate of the oxygen-enriched aqueous liquid stream is modulated so as to maintain a dimensionless number, defined as: ##EQU1## wherein .rho.=density of the pressurized aqueous liquid within the pipeline,D=internal diameter of the pipeline,V=mean liquid velocity of the pressurized aqueous liquid stream within the pipeline,g.sub.c =gravitational constant,.DELTA.P=pressure drop of the aqueous liquid stream flowing through the pipeline,L=length of the pipeline, andt=mean transit time required by the aqueous liquid stream to flow through the pipeline,at a value in the range of about 1.times.10.sup.-10 to about 5.times.10.sup.-7 until the stream is commingled with the body of water, the oxygen concentration of which is to be enriched.
