Abstract: A fast and sensitive method and device for protein sequencing are disclosed. The method uses a combination of Edman degradation chemistry and mass spectrometry to sequence proteins and polypeptides. A peptide degradation reaction is performed on a polypeptide or protein ion reactant in the gas phase. The reaction yields a first ion product corresponding to a first amino acid residue of the polypeptide or protein reactant and a polypeptide or protein fragment ion. The mass-to-charge ratio for the first ion product, or the polypeptide or protein fragment ion, or both, is then determined. The first amino acid residue of the polypeptide or protein reactant is then identified from the mass-to-charge ratio so determined.

Abstract: Provided is a process for adsorptive separation of p-xylene from an aromatic hydrocarbon mixture comprising other isomers of xylene, and a device used therein. More specifically, the present invention provides a separation process employing simulated moving bed (SMB) adsorptive chromatography, characterized by subjecting the extracts eluted from a plurality of adsorption chambers arranged in parallel, to a crystallizer for additional separation, thereby improving productivity, and a device used therein.

Abstract: Provided is a process for adsorptive separation of p-xylene from an aromatic hydrocarbon mixture comprising other isomers of xylene, and a device used therein. More specifically, the present invention provides a separation process employing simulated moving bed (SMB) adsorptive chromatography, characterized by pretreating a fluid mixture, i.e. the feed, by using single adsorption chamber so as to raise the concentration of a component to be separated, and then carrying out the simulated moving bed adsorptive separation, thereby improving productivity, and a device used therein.

Abstract: Ionene polymers having biologically-active organic and/or inorganic anions are described. Methods to prepare the ionene polymers, compositions containing them and their methods of use are also described.

Abstract: The apparatus for activating carbon-containing material has an inlet for feeding carbon-containing material into a drum-shaped reactor, which is arranged so that its axis is substantially horizontal and has a cylindrical helix for moving the material about and along its axis. Heating burners are arranged outside the drum-shaped reactor and ducts are provided for introducing a stream of superheated steam inside the drum-shaped reactor. There are also discharge ports for discharging the activated carbon-containing material outside the drum-shaped reactor.

Abstract: An apparatus and method for recovering carbon from a carbon-containing gas are provided. The apparatus comprises a burner assembly adapted to deposit carbon from the carbon-containing gas on the interior surface of a rotatable cylinder that is disposed in either a horizontal or inclined relation to a supporting surface. A device is provided for removing the deposited carbon from the interior surface of the rotatable cylinder, whereby the carbon deposited on the cylinder is recovered. Louvers having a series of baffles are mounted over the ends of the cylinder for regulating air flow into and flue gas flow from the cylinder, and elongate shafts having louvers therein are mounted to the ends of the cylinder for dissipating heat generated during operation by free or forced convection of air through the shaft louvers.

Abstract: An improvement in a tritium control system based on a catalytic oxidation reactor wherein accidental releases of tritium into room air are controlled by flooding the catalytic oxidation reactor with hydrogen when the tritium concentration in the room air exceeds a specified limit. The sudden flooding with hydrogen heats the catalyst to a high temperature within seconds, thereby greatly increasing the catalytic oxidation rate of tritium to tritiated water vapor. Thus, the catalyst is heated only when needed. In addition to the heating effect, the hydrogen flow also swamps the tritium and further reduces the tritium release.
