Abstract: This invention is a combination process for producing elemental bromine using bromide salt feedstocks. The process involves acidifying an inorganic bromide salt with a strong and concentrated acid, preferably sulfuric acid, to produce a gaseous HBr stream. The HBr stream is then mixed with an O2-containing gas and passed to an oxidation reactor where it is catalytically oxidized to produce a stream of Br2 and H2O. The hot reactor effluent is quenched and the product Br2 is separated from the H2O. In the figure, HBr stream is introduced into an evaporator (204) and to superheater (206). The O2 feedstream (208) is warmed. A reactor feedstream (214) is introduced into (216). The reaction product stream (218) is cooled in stages (220) and (222) and condensed. The condensate is then separated into a Br2 stream (224) added to water stream giving stream (226) and (228). The device (230) is a separator and (232) is a refrigeration unit. The resulting stream (234) is mixed with Br2 stream (224) giving noncondensed oxygen vapor stream (236) which is scrubbed in a gas treater (238). Distillation column (242) produces two streams (252) and (244). The overhead vapor stream (244) is condensed in overhead condenser (246) and collected in drum (248). The stream (250) is mixed with other streams. Device (256) is an absorption tower and (258) is the Br2 product stream.

Abstract: The present invention provides reaction mixtures useful for oxidation of olefins to carbonyl products, comprising an olefin and an aqueous catalyst solution comprising a palladium catalyst, a polyoxoacid or polyoxoanion oxidant comprising vanadium, and dissolved olefin. It also provides processes for oxidation of olefins to carbonyl products, comprising mixing an olefin with an aqueous catalyst solution. It also provides processes for oxidation of olefins to carbonyl products by dioxygen, comprising mixing an olefin with an aqueous catalyst solution, and further comprising mixing dioxygen with the aqueous catalyst solution. In certain reaction mixtures and related processes of the present invention, the concentration of dissolved olefin in the aqueous catalyst solution is effective for its oxidation rate to not be limited by its rate of its diffusion into the aqueous solution. In other reaction mixtures and related processes of the present invention, the concentration of dissolved olefin in the aqueous catalyst solution is effective for its oxidation rate to be proportional to the palladium catalyst concentration. In other processes of the present invention, the olefin is mixed with the aqueous catalyst solution under mixing conditions effective for providing an olefin oxidation rate of at least 1 (millimole olefin/liter solution)/second. In other processes of the present invention, dioxygen is mixed with an aqueous reduced vanadium-polyoxoanion solution under mixing conditions effective for providing a dioxygen reaction rate of at least 1 (millimole dioxygen/liter solution)/second. In other reaction mixtures and related processes of the present invention, the aqueous solution is essentially free of sulfuric acid and sulfate ions.

Abstract: A method for reducing the amount of carbon monoxide produced in the combination of carbonaceous fuels. The fuel (1) is coated on at least a portion of its exterior surface with a microporous layer of solid particulate matter (9) which is non-combustible at temperatures in which the carbonaceous fuel combusts. This invention is particularly applicable in the reduction of carbon monoxide in the burning of carbonaceous fuel elements found in currently available 'smokeless' cigarettes.
