    摘要： The present invention relates to a water-gas shift process which is carried out in a non-aqueous, high boiling liquid medium, either in an ebullated or slurry mode. The function of the liquid is to provide a heat sink for the exothermic reaction thereby allowing for better performance and longer catalyst life. The process, termed "liquid phase shift" (LPS) preferably uses commercially available vapor-phase low temperature shift (LTS) catalysts to accomplish the shift reaction. Because of the isothermality of the LPS process and its ability therefore to take advantage of higher catalyst activity, the average operating temperature is typically 260.degree. C. (500.degree. F.). This compares favorably to the lower average operating temperature for the conventional vapor-phase LTS process, which is typically 240.degree. C. (465.degree. F.). In addition, the LPS process can handle high carbon monoxide content feeds, e.g. 75 vol % carbon monoxide on a dry basis, without experiencing excessive catalyst deactivation. High carbon monoxide content feeds cannot be handled by convention LTS processing.

    摘要： A two stage pressure swing adsorption process is set forth for producing the less strongly adsorbed component of a feed gas mixture wherein the first stage utilizes a first adsorbent for bulk removal of the more strongly adsorbed component and wherein the second stage utilizes a second adsorbent for trace removal of the more strongly adsorbed component. A further feature of the present invention is that the desorbed gas from the second stage's depressurization step (consisting primarily of the desired less strongly adsorbed component) is recycled to the first stage in order to improve its performance. In a preferred embodiment of the present invention, high purity nitrogen (less than 1000 ppm oxygen, preferably less than 100 ppm oxygen) is produced from an air feed using a kinetically controlled carbon molecular sieve adsorbent in the first stage and an equilibrium controlled metal complex-based adsorbent in the second stage.

    摘要： The present invention is a separation process for atmospheric gases. In the process, an atmospheric gas stream, for example air, is compressed and may be partly condensed prior to introduction into a vortex tube air separator. The performance of the tube separation can be upgraded, i.e. by improving the concentration and/or purity of the main oxygen stream, by enhancing the separator efficiency of the vortex tube (VT) apparatus. One approach is by selectively refrigerating the cold end of the tube with partial recycle of nitrogen gas waste stream, effecting a rectification section. Another approach is to increase the heat transfer between the outlet gas stream and the liquid film flowing along the curvilinear periphery of the separator means, by mechanical innovations in its configuration.

    摘要： A coal liquefaction system is disclosed with a novel preasphaltene recycle from a supercritical extraction unit to the slurry mix tank wherein the recycle stream contains at least 90% preasphaltenes (benzene insoluble, pyridine soluble organics) with other residual materials such as unconverted coal and ash. This subject process results in the production of asphaltene materials which can be subjected to hydrotreating to acquire a substitute for No. 6 fuel oil. The preasphaltene-predominant recycle reduces the hydrogen consumption for a process where asphaltene material is being sought.
