    摘要: A process is provided for producing reduced acid lignocellulosic-derived bio-oil. treating a lignocellulosic biomass feedstock in a moving bed reactor with a metal oxide catalyst on an oxide support under treating conditions to produce a treated stream; directing spent metal oxide catalyst from the moving bed reactor to a fluidized bed regenerator, the spent metal oxide catalyst resulting from treating the lignocellulosic biomass feedstock with the metal oxide catalyst; regenerating the spent metal oxide catalyst in the fluidized bed regenerator by removing coke from the spent metal oxide catalyst in a combustion process that regenerates the spent metal oxide catalyst into the metal oxide catalyst; and returning to the moving bed reactor the metal oxide catalyst that has been regenerated in the fluidized bed regenerator. The obtained bio-oil is particularly suitable as a renewable feedstock for hydroprocessing in biofuel manufacture.

    摘要: An apparatus and process for fractionation of component mixtures by chromatography or adsorption on a simulated mobile bed comprising three, four or five zones is described. A compressed gas is injected as eluent (IE, IR) using a compressor or pump, the pressure being lower than the critical pressure of the gas. At any point in at least one zone and preferably at any point in at least two zones from the eluent injection point (IR), the gas has a compressibility coefficient substantially different to 1. A supercritical fluid or a subcritical liquid may equally be injected as the eluent. The pressure between each zone may be altered.

    摘要: Targetry coupled separation refers to enhancing the production of a predetermined radiation product through the selection of a target (including selection of the target material and the material's physical structure) and separation chemistry in order to optimize the recovery of the predetermined radiation product. This disclosure describes systems and methods for creating (through irradiation) and removing one or more desired radioisotopes from a target and further describes systems and methods that allow the same target to undergo multiple irradiations and separation operations without damage to the target. In contrast with the prior art that requires complete dissolution or destruction of a target before recovery of any irradiation products, the repeated reuse of the same physical target allowed by targetry coupled separation represents a significant increase in efficiency and decrease in cost over the prior art.

    摘要: An improved simulated moving bed separation system is disclosed. The improved novel system is characterized by being provided with rotary valves or check valves or both. The rotary valves are provided at the position where desorbing liquid is introduced, the position where the extract is taken out, the position where the feedstock is introduced and the position where the raffinate is taken out and the rotary valves are intermittently switched on and off, whereby the liquid take out of the unit packed bed preceding the position where the desorbing liquid is introduced is supplied to the circulation pump. The check valves are provided in the fluid flow passage between a unit packed bed and an extract draw-out port positioned in the next unit packed bed in the direction in the next unit packed bed in the direction of fluid flow. Thus liquid flow is smoothly controlled and the more effective separation is realized.

A technique is used, known as the simulated countercurrent technique, in a separation column which is filled with sorbent and has 6 zones 6, 5, 4, 3, 2 and 1 which have different functions, and the following sequence of steps is carried out: strong solvent S.sub.2 is introduced, an extract E.sub.2 with strong solvent is removed, weak solvent S.sub.1 is introduced. The extract with weak solvent E.sub.1 is drawn off, the separating mixture is introduced, refined substance is drawn off with weak solvent R, rinsing solvent (S.sub.1) is introduced, a current Rcy is recycled alternatingly towards the feed of strong solvent S.sub.2 and then towards the feed of weak solvent S.sub.1. A current coming from zone 6 is sent alternatingly to an outlet for the extract with strong solvent E.sub.2, then towards the intake of the fifth zone. The various feeds and substances removed are periodically advanced synchronously through the column. Application in particular for the separation of glucose, xylose and arabinose and for the separation of paraxylene, orthoxylene and metaxylene and ethyl benzene.
