Abstract

Method for removal of radioactive cesium from a hot vapor, such as high temperature steam, including the steps of passing input hot vapor containing radioactive cesium into a bed of silicate glass particles and chemically incorporating radioactive cesium in the silicate glass particles at a temperature of at least about 700.degree. F.

Method of removing cesium from steam

Patent Application Carson, Jr, N J ; Noland, R A ; Ruther, W E

The foregoing objects of the present invention are achieved by a method for removing radioactive cesium from a hot vapor, such as steam, by a technique wherein the cesium chemically reacts with a filtering material which retains the cesium without causing degradation of the filtering material. The method is carried out at temperatures in the range of from about 700{degree}F to about 1000{degree}F, and even higher, but it preferably is utilized at a temperature of at least about 800{degree}F. The method uses a silica glass which is preferably in the form of spheres as the filter material. The preferred materialmore »« less
THE VOLATILIZATION AND COLLECTION OF RUTHENIUM AND CESIUM IN A SYSTEM FOR INCORPORATING FISSION PRODUCTS INTO GLASS

Technical Report Bancroft, A R ; Watson, L C ; Hoelke, C W

During the incorporation of fission products into glass, about 50% of the ruthenium and 2% of the cesium was released as vapor from the mixes. It was not possible to reduce significantly the extent of Ru and Cs volatilization. It was possible to remove the isotopes efficiently from the furnace off-gases to allow their reincorporation into glass. Laboratory tests indicated that a column packed with granules of siliceous firebrick coated with iron oxide was abcut 99% efficient for retnining Ru and better than 95% efficient for Cs. Bed temperatures near 600 deg C were best and a 200 deg spreadmore »« less
Multi-zone coal conversion process using particulate carrier material

Patent Chervenak, M C ; Johanson, E S ; Rakow, M S

A multiple-zone fluidized bed coal conversion process is claimed for producing fuel gas and distillate liquid products. The coal is fed into an upper fluidized bed maintained at 950/sup degrees/ to 1500/sup degrees/ F for devolatilization. The resulting coke and some tars are deposited on a particulate carrier material, which descends along with the larger particles of unreacted coal through a stripping zone into a lower fluidized bed gasification zone, which is maintained at 1700/sub degrees/ to 2000/sup degrees/ F by steam and O/sub 2/-containing gas introduced to gasify the coke and char. Fine particles of unreacted coal and carriermore »« less
Process for recovering oil from raw oil shale using added pulverized coal

Patent Minden, C S

A continuous process is described for treating raw shale oil to produce shale oil of improved quality and yield and reduced cost which includes the following steps: a. crushing and grinding the raw oil shale, b. heating and drying the crushed and ground shale, c. passing the heated and dried shale particles to a slurry mixer where they are mixed with hot heavy oil recycle, d. passing the slurry into a pressurized hydropyrolysis chamber where it is treated with hydrogen under a pressure of 500 to 2000 psi and a temperature of 400 degrees C. to 475 degrees C. formore »« less
Combined process for coal pyrolysis and char gasification

Patent Gorin, E

This patent describes the method of converting coal to gaseous products. The method consists of: (a) admixing finely divided coal into a hydrogencontaining recycle gas stream, (b) providing a vertically elongated pyrolysis zone, (c) introducing the coal-containing recycle gas stream of step (a) into a lower region of the pyrolysis zone, (d) introducing a finely divided particulate heated char into a lower region of the pyrolysis zone, (e) passing the resulting mixture of heated char, finely divided coal, and recycle gas upwardly through the pyrolysis zone at a temperature between about 500/sup 0/ and about 950/sup 0/ C. and amore »« less
