摘要:
A system for treating a treatable material containing a noxious component, which comprises a mixer for mixing a treatment agent containing alkali material with the treatable material to form a mixture, at least one first heat treating furnace for producing a low oxygen concentration atmosphere, a first heating device located outside the first furnace to heat it at a first temperature at which the treatable material is decomposed to generate a substance containing the noxious component, at least one separate second heat treating furnace, and a second heating device located outside the second furnace for heating the treatable material residue at a second temperature at which carbonization of the treatable material residue takes place.
摘要:
The invention is a novel process for extracting salts from their aqueous solutions for contacting an aqueous salt solution with a substantially water-immiscible solution of an organic acid and an organic base. The resulting salt-containing organic extract is separated from the salt-depleted aqueous raffinate and the salt in turn usually stripped from the extract. Conveniently, water can be used as the stripping agent.
摘要:
A method of stabilizing nuclear material is disclosed. Oxides or halides of actinides and/or transuranics (TRUs) and/or hydrocarbons and/or acids contaminated with actinides and/or TRUs are treated by adjusting the pH of the nuclear material to not less than about 5 and adding sufficient MgO to convert fluorides present to MgF2; alumina is added in an amount sufficient to absorb substantially all hydrocarbon liquid present, after which a binder including MgO and KH2PO4 is added to the treated nuclear material to form a slurry. Additional MgO may be added. A crystalline radioactive material is also disclosed having a binder of the reaction product of calcined MgO and KH2PO4 and a radioactive material of the oxides and/or halides of actinides and/or transuranics (TRUs). Acids contaminated with actinides and/or TRUs, and/or actinides and/or TRUs with or without oils and/or greases may be encapsulated and stabilized by the binder.

摘要:
An inexpensive one-step process is disclosed for producing the lower hydrates of magnesium dihalide by comminuting hydrated magnesium dihalide and anhydrous magnesium dihalide. Also the use of such hydrous magnesium dihalide products in the olefin polymerization catalysts.
摘要:
Provided is a carrier for an olefin polymerization catalyst which carrier comprises a substance obtained by adding a liquid organic compound not dissolving a magnesium halide into a liquid medium having dissolved therein a substance which contains the magnesium halide as at least one component, the liquid medium further containing an oxide of Group II-IV metal or metals in the Periodic Table, followed by cooling to a temperature not higher than 0.degree. C. and subsequent heat treatment at a temperature in the range of 40.degree. to 200.degree. C.
摘要:
The gas stream obtained from the pyrolysis of solid organic wastes and containing halogens, particularly chlorine in the form of the corresponding hydrogen halide is processed to obtain a halide free pyrolytic oil. The gas stream after solids removal is contacted with a solid metal halide acceptor above the dew point of pyrolyzate to form the corresponding metal halide which may be discarded. As an alternative the metal halide can be treated to release the hydrogen halide which is recovered as an acid and the acceptor regenerated for recycle. The preferred acceptor is calcium carbonate.
