Title: Method of desulfurization of fossil fuel with flavoprotein
Inventor: SQUIRES CHARLES H
IPC: C12N1/21
Filed: 1995-12-05
Abstract: The invention relates to the discovery that the rate of reaction of the desulfurization of fossil fuels is enhanced by the addition of a flavoprotein to the biocatalyst. The invention is drawn to a method for enhancing the rate of desulfurizing a fossil fuel containing organic sulfur compounds, comprising the steps of: a) contacting the fossil fuel with an aqueous phase containing a biocatalyst capable of cleaving carbon-sulfur bonds and a rate-enhancing amount of a flavoprotein, thereby forming a fossil fuel and aqueous phase mixture; b) maintaining the mixture of step (a) under conditions sufficient for cleavage of the carbon-sulfur bonds of the organic sulfur molecules by the biocatalyst, thereby resulting in a fossil fuel having a reduced organic sulfur content; and c) separating the fossil fuel having a reduced organic sulfur content from the resulting aqueous phase. The invention also relates to a recombinant microorganism containing one or more recombinant DNA molecules which encode a biocatalyst capable of desulfurizing a fossil fuel containing organic sulfur molecules and which encode a flavoprotein. The invention also relates to a composition comprising (a) a biocatalyst capable of desulfurizing a fossil fuel containing organic sulfur molecules and (b) a flavoprotein.

Title: Method of solvent extraction of nickel sulfate
Inventor: TAKAISHI KAZUYUKI
IPC: C01G53/10
Filed: 1998-04-29
Abstract: Provided is an economical method of solvent extraction of a nickel sulfate solution to purify nickel sulfate, in which the organic phase obtained is prevented from being contaminated with impurities such as sodium and ammonium, and a high-purity nickel sulfate solution is obtained with ease. The method uses a multi-stage, counter-current, organic solvent extraction system composed of at least two extractors as connected in series, and comprises a first extraction step of feeding a crude nickel sulfate solution that contains impurities of essentially sodium and ammonium into a second-stage extractor, followed by processing therein the crude nickel sulfate solution with an organic extractant having been fed into the second-stage extractor from the first-stage extractor, within a pH range falling between 6.5 and 7.0 in a manner of counter-current extraction reaction therebetween to thereby make a part of nickel existing in the crude nickel sulfate solution extracted out into the organic extractant; and a second extraction step of transferring the nickel-containing, organic phase to an organic phase-scrubbing step of scrubbing it to remove sodium and ammonium from the thus-transferred, nickel-containing organic phase, while transferring the crude nickel sulfate solution, which has been processed in the first extraction step and from which a part of nickel has been removed, to the first-stage extractor, followed by further processing therein the thus-transferred crude nickel sulfate solution with a fresh organic extractant, within a pH range falling between 5.5 and 6.5 in a manner of counter-current extraction reaction therebetween to thereby make the remaining part of nickel still existing in the crude nickel sulfate solution extracted out into the organic extractant. In the method, the nickel-containing organic phase as separated in the second extraction step is divided into two portions, and one of these portions is used as the organic extractant to be fed into the second-stage extractor while the other is transferred to a by-pass, organic phase-scrubbing step of scrubbing it to remove sodium and ammonium from the thus-transferred, nickel-containing organic phase.
