    • 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。
