    摘要： A gas distribution grid for a slurry reactor includes a plurality of gas injectors horizontally arrayed across, and extending through, an otherwise gas and liquid impervious plate. The injectors have a throat open at both ends, with a gas pressure reducing bore at one end which is the entrance end and with the other end opening into an upward opening cone. Flow diverting means in the injectors prevents slurry solids from entering the throat and being attrited by the high velocity gas jet exiting the bore into the throat. It is preferred that the gas injectors not protrude above the top surface of the grid and flat space is eliminated by means such as angular fillers, to prevent solids accumulation top of the grid. A chamber may be present at the junction of the bore and throat to prevent unrestricted expansion of the gas jet entering the throat. This is useful for injecting gas into a reactive hydrocarbon synthesis slurry in a slurry reactor, with reduced catalyst attrition and deactivation.

    摘要： The present invention addresses the need for improved methods and apparatuses of transplanting cells to injured or diseased cornea. The methods disclosed provide for culture of cells on the concave surface of a contact lens, followed by application of the contact lens to the eye, thereby permitting repopulation of the corneal region by the cells. A particular use for the present invention involves the transfer of genetically altered cells.

    摘要： There is provided a process for regenerating the activity of used metal catalysts for the hydrogenation of carbon monoxide comprising decreasing the hydrocarbon content thereof, calcining under an oxidant-containing atmosphere, impregnating with a solution of at least one of a metal compound, calcining under an oxidant-containing atmosphere and activating by contacting with a hydrogen-contacting gas at elevated temperatures to form an active catalyst. The process regenerates and enhances both supported and dispersed active metal (DAM) catalysts. Used catalysts enhanced by the process are initially treated to decrease their hydrocarbon content. The treatment may be carried out in a single reactor, or by carrying out up to all steps after catalyst may be withdrawn from a reactor and returned to at least one reactor, both preferably during operation thereof. Up to all steps may be effected in a subsequent reactor, or in specialized apparatus.

    摘要： A reversibly deactivated hydrocarbon synthesis catalyst in a hydrocarbon synthesis slurry is rejuvenated by successively passing the slurry through at least two rejuvenation stages external of the slurry reactor, each of which comprises a rejuvenation zone followed by an offgas removal zone. This is accomplished by using a lift pipe outside the reactor into which slurry from the reactor is passed and contacts a catalyst rejuvenating gas to partially rejuvenate the catalyst particles and form a rejuvenation offgas. The gas and slurry mixture are passed into a vessel in which the gas is removed from the slurry. Rejuvenation gas is bubbled into the slurry in the vessel to further rejuvenate the catalyst. A gas removing downcomer removes gas from the slurry in the vessel before it is passed back into the reactor. The rejuvenation gas also acts as a lift gas in the lift pipe.

    摘要翻译： 在烃合成浆料中可逆失活的烃合成催化剂通过连续使浆料通过浆料反应器外部的至少两个再生阶段而恢复活力，每个回收阶段包括再生区，随后是除气区。 这通过在反应器外部使用提升管来实现，在该反应器中通过反应器的浆料通过该提升管并接触催化剂再生气体以部分地使催化剂颗粒恢复活力并形成复原废气。 将气体和浆料混合物送入从浆液中除去气体的容器中。 将再生气体鼓泡到容器中的浆料中以进一步使催化剂复原。 气体去除降液管在其返回到反应器之前从容器中的浆液中除去气体。 再生气也起到升降气体的作用。

    摘要： Slurry bubble columns equipped with downcomers which have high efficiency gas disengagement means fitted on top of the slurry liquid reaction mixture comprising an inverted channel having a gas vent extending out of the apex of the inverted channel and a liquid by-pass pipe extending from the side of the inverted channel at a point below the apex to under the liquid level and emptying into the downcomer. The inverted channel is fitted to the top of said downcomer and the bottom edge of which inverted channel is in contact with the surface of the slurry mixture in the slurry bubble column reaction zone. Improved catalyst distribution and circulation, mass and heat transfer results from catalyst in gas-lean slurry flowing through the liquid by-pass tubes in the inverted channel and flowing into and down the downcomer to the bottom of the bubble column reactor. Hydrogen or any rejuvenating gas can be introduced into the bottom of the downcomer to restore catalyst activity as the catalyst moves down the downcomer.
