Abstract: An integrated middle distillate upgrading process and unit are disclosed. A middle distillate side-stream of a conventional single stage hydrocracking process is circulated to a hydrotreating stage such as an aromatics saturation reactor and/or a catalytic dewaxing reactor to effect middle distillate upgrade. The upgraded product is then finished in a fractionation stage side-stripper column. The integrated hydrotreating reactor can share the duty of existing hydrocracker stage equipment and take advantage of existing process heat to eliminate the need for much of the equipment generally required by a stand-alone hydrotreating reactor of the prior art.

Abstract: A method and apparatus for desulfurizing a gas and regenerating a sorbent is disclosed. The sulfur-containing feed gas which can be an effluent gas from a coal gasification reactor, for example, is desulfurized with a particulated metallic oxide sorbent in a transport riser. The sulfided sorbent is than separated from a desulfurized effluent gas and regenerated by contact with an oxygen-containing gas in a transport riser. The regenerated sorbent is separated from an SO.sub.2 containing offgas and recycled to the desulfurization step. The degree of sorbent conversion in the desulfurization step is held at a low level and the sorbent regeneration rate is increased to avoid excessive temperature rise in the regeneration step. In such manner, sorbent cooling can be substantially eliminated. The regeneration riser preferably comprises a once-through lift riser to minimize the riser transport gas requirements to just oxidant gas or oxidant gas mixed with a reduced amount of diluent gas.

A light-tight enclosure surrounds the aperture in the panel on the side of the panel opposite the side on which the parenteral drug is inspected. Interior surfaces of the enclosure have black surfaces with finishes to achieve low light reflection. The combination of the aperture and the black enclosure provides enhanced blackness that is not likely to be affected by dust, dirt or surface damages. Hence, greater accuracy and reliability in black background particulate inspection is achieved.

Abstract: Alkanes are dehydrogenated by passage through alternating dehydrogenation zones and selective oxidation zone(s), in which latter zone(s) hydrogen produced in the preceding endothermic dehydrogenation reaction is selectively oxidized to generate heat for the succeeding dehydrogenation reaction. New catalyst compositions are prepared comprising reduced and sulfided nickel crystallites on siliceous supports which have been treated with chromium compounds and oxidized to provide surface-anchored chromyl species. Also new catalyst compositions are prepared by sulfiding nickel-containing compositions with carbonaceous sulfur compounds such as dialkylsulfoxides. Another embodiment of the invention is catalyst and dehydrogenation therewith, in which pores having radius of 50 to 200 Angstroms occupy pore volume from 0.30 to 1.50 ml per gram of the support, and pores having radius of 20 to 50 Angstroms occupy pore volume less than 0.1 ml per gram of the support.
