摘要： The use of one or more alkali metals, preferably sodium, to remove sulfur from hydrocarbon streams containing up to about 100 wppm sulfur. The hydrocarbon stream is introduced into a reactor where it is contacted with one or more alkali metals. The treated hydrocarbon stream is then subjected to a water wash thereby resulting in an aqueous phase fraction and a hydrocarbon phase fraction. The aqueous phase fraction, which is separated from the hydrocarbon phase fraction contains water-soluble sodium moieties.

摘要： Refractory or hard sulfur found in a hydrocarbon stream containing refractory sulfur heterocycle compounds, particularly those exhibiting steric hindrance, is removed from the stream by contacting it with a sodium reagent comprising a sodium component, having free sodium, supported on a solid support component. If the hydrocarbon stream contains more labile or easy sulfur, then it is treated, typically by hydrodesulfurization, to remove at least most of the labile sulfur before it is contacted with the sodium reagent. This is useful for bringing the sulfur level of middle distillate fuel streams, such as diesel and jet fuel fractions, down to a level of less than about 10 wppm, employing conventional hydrodesulfurizing catalysts and conditions.
摘要翻译：在含有难溶性硫杂环化合物的烃流中，特别是那些表现出空间位阻的烃流中发现的耐火或硬硫通过与包含负载在固体支持组分上的具有游离钠的钠组分的钠试剂接触而从流中除去。如果烃流含有更多的不稳定或易硫化物，那么通常通过加氢脱硫来处理至少大部分不稳定的硫，然后再与钠试剂接触。这对于使用常规的加氢脱硫催化剂和条件将中等馏出物燃料流（例如柴油和喷气燃料馏分）的硫含量降低到低于约10wppm的水平是有用的。

摘要： A gas separation process uses a structured particulate bed of adsorbent coated shapes/particles laid down in the bed in an ordered manner to simulate a monolith by providing longitudinally extensive gas passages by which the gas mixture to be separated can access the adsorbent material along the length of the particles. The particles can be laid down either directly in the bed or in locally structured packages/bundles which themselves are similarly oriented such that the bed particles behave similarly to a monolith but without at least some disadvantages. The adsorbent particles can be formed with a solid, non-porous core with the adsorbent formed as a thin, adherent coating on the exposed exterior surface. Particles may be formed as cylinders/hollow shapes to provide ready access to the adsorbent. The separation may be operated as a kinetic or equilibrium controlled process.

摘要： A method and system for drilling a wellbore is described. The system includes a wellbore with a variable density drilling mud, drilling pipe, a bottom hole assembly disposed in the wellbore and a drilling mud processing unit in fluid communication with the wellbore. The variable density drilling mud has compressible particles and drilling fluid. The bottom hole assembly is coupled to the drilling pipe while the drilling mud processing unit is configured to separate the compressible particles from the variable density drilling mud. The compressible particles in this embodiment may include compressible hollow objects filled with pressurized gas an configured to maintain the mud weight between the fracture pressure gradient and the pore pressure gradient. In addition, the system and method may also manage the use of compressible particles having different characteristics, such as size, during the drilling operations.
