A relatively solid, stable biomass reaction product is provided produced from microorganisms having metal uptake properties when contacted by an aqueous solution containing metal cations. The biomass reaction product is produced by treating cells thereof with a caustic solution, whereby the biomass reaction product after drying is characterized in the particulate state of having substantially enhanced uptake of metal cations from aqueous solutions as compared to the metal uptake property of the ...

A process for economically recovering char, oil and fuel gas from vehicle tires is disclosed, for either whole tires or physically fragmented tires. The tires may be washed to remove dirt and road film. The tires are dried and preheated with super-heat steam. The hot tires are pyrolyzed to partially devolatize a major portion of the hydrocarbons and produce a char that can be separated from the steel and fiberglass. The char may be subsequently pyrolyzed with microwaves that elevate the tire tem...

A recovery system for decelerating/stabilizing and protecting space vehicles, boosters, astronauts, equipment and like payloads, including a paracanopy defined by a frusto-conical flexible uninflated skin forming a decelerator/stabilizer surface having a small inflated torus at it leading end and a larger trailing torus at its trailing end with an inflated annular protective sheath therebetween protecting the payload housed therein, duct means between the toruses and the annular sheath for formi...

A (trifluoromethyl)naphthalene which has been prepared by reacting a halonaphthalene with a trifluoroacetate salt in the presence of cuprous iodide and a dipolar aprotic solvent is recovered by (1) replacing the dipolar aprotic solvent in the final reaction mixture with an alkane containing 6-12 carbons, (2) heating the resultant slurry to a temperature sufficient to dissolve the organic ingredients, (3) allowing the inorganic ingredients of the slurry to settle, (4) decanting the organic layer,...

In a method of recovering silver from an aqueous suspension, the suspension is admixed with a solution capable of converting silver halide to metallic silver to cause flocculation of the silver, the flocculated silver is separated from the aqueous phase, and the silver is recovered.

A recovery apparatus having a frame adapted for earth traversing movement along an elongated sheet bearing a crop to recover the crop; a first conveyor mounted on the frame for receiving the sheet and conveying the sheet therealong; a second conveyor mounted on the frame for overlaying the sheet and the crop borne thereby on the first conveyor and moving in a complementary direction to the first conveyor; finger members mounted on the second conveyor to maintain space between the second conveyor...

Actinides metals are recovered from spent nuclear fuel oxides containing fission products by a pyrochemical process. The process comprises, in part, electrorefining the metal complex from an anode by electrolytically oxidizing actinides into a salt and then electrodepositing actinides onto a cathode to form an actinide metal deposit. The actinide metal deposit is then melted to separate the salts and the actinide metals. The separated salt is recycled into an electrorefiner and the actinide meta...

An apparatus for economically recovering char, oil and fuel gas from vehicle tires is disclosed, for either whole tires or physically fragmented tires. The tires may be washed to remove dirt and road film. The tires are dried and preheated with super-heat steam. The hot tires are pyrolyzed to partially devolatize a major portion of the hydrocarbons and produce a char that can be separated from the steel and fiber glass. The char may be subsequently pyrolyzed with microwaves that elevate the tire...

An epoxidation reaction product formed by the molybdenum catalyzed reaction of propylene with tertiary butyl hydroperoxide to provide propylene oxide and tertiary butyl alcohol is separated by distillation into a propylene fraction, a propylene oxide fraction, a tertiary butyl alcohol fraction and a heavy liquid distillation fraction composed primarily of tertiary butyl hydroperoxide, tertiary butyl alcohol, dissolved molybdenum catalyst, and impurities including lower aliphatic C.sub.1 -C.sub.4...

A system and method for recovering clean water from the air flowing into and through a gas turbine engine. Low pressure air drawn from the engine compressor is fed to a receiver. Compressed air from a higher stage of the compressor is cooled by atmospheric air which may be previously spray-cooled. The compressed air is further cooled by heat exchange with exhaust air from the system, and then expanded to further cool the air and lower its pressure. The two flows of air are then mixed in a receiv...
