    • A method for chemical vapor deposition using a very fine atomization or vaporization of a reagent containing liquid or liquid-like fluid near its supercritical temperature, where the resulting atomized or vaporized solution is entered into a flame or a plasma torch, and a powder is formed or a coating is deposited onto a substrate. The combustion flame can be stable from 10 torr to multiple atmospheres, and provides the energetic environment in which the reagent contained within the fluid can be reacted to form the desired powder or coating material on a substrate. The plasma torch likewise produces the required energy environment, but, unlike the flame, no oxidizer is needed so materials stable in only very low oxygen partial pressures can be formed. Using either the plasma torch or the combustion plasma, coatings can be deposited and powders formed in the open atmosphere without the necessity of a reaction chamber, but a chamber may be used for various reasons including process separation from the environment and pressure regulation.
    • 使用在其超临界温度附近含有液体或液体状流体的试剂非常精细的雾化或蒸发的化学气相沉积方法,其中所得雾化或蒸发的溶液进入火焰或等离子体焰炬,并形成粉末 或涂层沉积在基底上。 燃烧火焰可以从10托稳定到多个大气压,并且提供能够使流体中包含的试剂反应以在基底上形成所需粉末或涂层材料的能量环境。 等离子体焰炬同样产生所需的能量环境,但是与火焰不同,不需要氧化剂,因此可以形成仅在非常低的氧分压下稳定的材料。 使用等离子体焰炬或燃烧等离子体,可以沉积涂层并且在开放气氛中形成粉末,而不需要反应室,但是可以由于各种原因使用室,包括与环境的分离和压力调节。

    • A method for causing a very fine atomization or vaporization of a liquid or liquid-like fluid, where the resulting atomized or vaporized solution is entered into engine, instrument or area for the fluid to be in mixed. The ability of the near supercritical atomizer to produce very fine droplets of a wide range of liquids without any aspirant is very important for number of industrial applications. Especially when the drop size can be so finely controlled. Industries needing such fine atomization include applications such as combustion, engines, scientific equipment, chemical processing, waste disposal control, cleaning, etching, insect control, surface modification, humidification and vaporization. It is important in these applications not to cause a decomposition of the material being atomized. Staying below the supercritical point normally enables no decomposition and/or no precipitation of components within the liquid or fluid in most applications, but a very fine atomization is obtained without the need of any aspirant.

    • Nanoparticulates of oxygen transfer materials that are oxides of rare earth metals, combinations of rare earth metals, and combinations of transition metals and rare earth metals are used as catalysts in a variety of processes. Unexpectedly large thermal efficiencies are achieved relative to micron sized particulates. Processes that use these catalysts are exemplified in a multistage reactor. The exemplified reactor cracks C6 to C20 hydrocarbons, desulfurizes the hydrocarbon stream and reforms the hydrocarbons in the stream to produce hydrogen. In a first reactor stage the steam and hydrocarbon are passed through particulate mixed rare earth metal oxide to crack larger hydrocarbon molecules. In a second stage, the steam and hydrocarbon are passed through particulate material that desulfurizes the hydrocarbon. In a third stage, the hydrocarbon and steam are passed through a heated, mixed transition metal/rare earth metal oxide to reform the lower hydrocarbons and thereby produce hydrogen. Stages can be alone or combined. Parallel reactors can provide continuous reactant flow. Each of the processes can be carried out individually.
    • 作为稀土金属的氧化物,稀土金属的组合以及过渡金属和稀土金属的组合的氧转移材料的纳米微粒用作各种工艺中的催化剂。 相对于微米级颗粒物,意想不到的大的热效率。 使用这些催化剂的方法在多级反应器中举例说明。 示例的反应器裂解C6至C20烃,对烃流进行脱硫并重整流中的烃以产生氢。 在第一反应器阶段,蒸汽和烃通过颗粒状混合稀土金属氧化物裂解较大的烃分子。 在第二阶段,蒸汽和烃通过使烃脱硫的颗粒材料。 在第三阶段中,烃和蒸汽通过加热的混合的过渡金属/稀土金属氧化物以重整低级烃并由此产生氢。 阶段可以单独或组合。 平行反应器可以提供连续的反应物流。 每个进程可以单独执行。
