摘要： A process for reducing sulfur content in a gaseous stream with the production of elemental sulfur by first treating the gaseous steam with hydrogenation and hydrolysis to convert substantially all of the sulfur components therein to hydrogen sulfide. Then reducing the water content of the gaseous stream to optimize chemical equilibrium. Thereafter, the gaseous steam is contacted in an oxidation reactor with an acid catalyst at a temperature of about 150.degree. C. to about 350.degree. C. to convert hydrogen sulfide to elemental sulfur. The product gas leaving the oxidation reactor is cooled to separate elemental sulfur by condensation. The acid catalyst is a shape selective zeolite, a metal-exchanged or impregnated alumina, or a mixture thereof. The alumina is gamma phase alumina impregnated with from about 0.2 wt % to about 2.0 wt % metal.

摘要： There is provided a process for regenerating a coked catalyst comprising a zeolite and a noble metal such as platinum. The process involves treating the coked catalyst under somewhat mild oxidation conditions, whereby a sufficient portion of the coke is removed from the catalyst to restore the hydrocarbon sorption properties of the zeolite component to the level observed in the non-coked form. Surprisingly, the original activity of the catalyst is substantially restored, even though a substantial amount of coke remains on the regenerated catalyst.

摘要： Systems and processes for removing a first sulfur compound from a hydrocarbon stream. The systems and process utilize at least one reaction vessel incorporating a hydrolysis catalyst suitable for hydrolyzing the first sulfur compound to a second sulfur compound. The reaction vessel also incorporates a sorbent material suitable for absorbing the second sulfur compound. Following hydrolysis of the first sulfur compound to the second sulfur compound and absorption of the second sulfur compound, a hydrocarbon-containing stream having a reduced sulfur content is produced. The hydrolysis catalyst and sorbent material may be provided in separate zones within the reaction vessel or provided as a mixture in a single zone. The hydrocarbon-containing stream having a reduced sulfur content is suitable for a variety of uses, including as a feedstreams for hydrogen plants, process gas streams for power generation plants, or for other uses for hydrocarbon-containing stream having reduced sulfur content.

摘要： This invention is a process for the upgrading of distillate feeds. A batch of supported hydroprocessing catalyst is placed in a reaction zone, which is usually a fixed bed reactor. The hydroprocessing catalyst comprises an effective amount of a noble metal or metals and has a specific activity. Both low aromatic diesel and jet fuel may be produced in separate blocks over the same catalyst batch, using different feeds and often different conditions. The activity of the catalyst is restored each time the feed is switched. When production is switched from jet fuel to low aromatics diesel, activity may be regained more quickly by holding the catalyst at a higher temperature than the reaction temperature for a specific period of time prior to dropping the temperature to the reaction temperature. Switching from one feed to the other may continue for about one year before the catalyst batch is changed. A dual catalyst system may alternatively be employed. In this case a hydroprocessing catalyst batch comprising an effective amount of at least one base metal is used in combination with the catalyst comprising an effective amount of at least one noble metal catalyst. The feed contacts the catalyst comprising the base metal before it contacts the catalyst comprising a noble metal. In a dual catalyst system, the feeds may be switched for about two years over the two catalyst batches before fresh catalyst is necessary.
摘要翻译：本发明是用于升级馏出物进料的方法。将一批负载型加氢处理催化剂置于反应区，反应区通常为固定床反应器。加氢处理催化剂包含有效量的贵金属或金属并具有比活性。低芳烃柴油和喷气燃料可以在相同的催化剂批次中使用不同的进料和通常不同的条件在不同的块中制备。每次切换进料时，催化剂的活性得到恢复。当生产从喷气燃料转换为低芳烃柴油时，通过在将温度降至反应温度之前将催化剂保持在比反应温度更高的温度持续一段特定时间，可以更快地恢复活性。在催化剂批次改变之前，从一个进料到另一个进料的切换可能会持续约一年。可以采用双重催化剂体系。在这种情况下，包含有效量的至少一种贱金属的加氢处理催化剂批料与包含有效量的至少一种贵金属催化剂的催化剂组合使用。在与包含贵金属的催化剂接触之前，进料接触包含贱金属的催化剂。在双重催化剂体系中，在新催化剂需要之前，进料可以在两个催化剂批次之间切换大约两年。
