摘要： To further isolate the scattered light 112 of a specific particle from the scattered light of a different particle, a pin hole device 116 can be used. The pin hole device 116 prevents unfocused light from other particles from entering the second plane 118, thus isolating a desired, focused image of one particle 110 of the sample 106. In one embodiment, the pin hole 116 has a size of several microns. At the second plane 118, a traditional imaging detection device 120 detects the defocused light. The position of the second image plane 118 is chosen for good angular resolution of the scattered light 112, and at the same time gives enough light for the imaging detection device 120 to obtain a sufficient reading.

摘要： Aspects of the present invention relate to compositions and methods for the use of ionic liquids with dissolved metal compounds as catalysts for a variety of chemical reactions. Ionic liquids are salts that generally are liquids at room temperature, and are capable of dissolving a many types of compounds that are relatively insoluble in aqueous or organic solvent systems. Specifically, ionic liquids may dissolve metal compounds to produce homogeneous and heterogeneous organometallic catalysts. One industrially-important chemical reaction that may be catalyzed by metal-containing ionic liquid catalysts is the conversion of methane to methanol.

摘要： Described herein are compositions and methods for using metal oxides to upgrade oil. Metal oxides may be used as catalysts to reduce the TAN of the oil by converting carboxylic acids such as naphthenic acids into non-corrosive products. In some cases, the conversion occurs by a decarboxylation of the carboxylic acid to produce CO2. A second process promoted by metal oxides is hydrocarbon cracking. Cracking decreases the viscosity and increases the API, and produces lower molecular-weight hydrocarbons that are useful for many fuels and lubricants. Reductions in TAN and the increases in API improve the quality of increase the value of oil.
摘要翻译：这里描述的是使用金属氧化物来提高油的组合物和方法。金属氧化物可以用作催化剂，通过将羧酸如环烷酸转化成非腐蚀性产物来降低油的TAN。在一些情况下，转化通过羧酸的脱羧作用产生CO 2。金属氧化物促进的第二个过程是烃裂解。开裂降低粘度并增加API，并产生较低分子量的碳氢化合物，可用于许多燃料和润滑剂。减少TAN和API的增加提高了油价的提高的质量。
