摘要:
Natural gas and petrochemical processing systems including oxidative coupling of methane reactor systems that integrate process inputs and outputs to cooperatively utilize different inputs and outputs of the various systems in the production of higher hydrocarbons from natural gas and other hydrocarbon feedstocks.
摘要:
Nanowires useful as heterogeneous catalysts are provided. The nanowire catalysts are useful in a variety of catalytic reactions, for example, the oxidative coupling of methane to ethylene. Related methods for use and manufacture of the same are also disclosed. More specifically, a catalyst comprising an inorganic catalytic polycrystalline nanowire, the nanowire having a ratio of effective length to actual length of less than one and an aspect ratio of greater than ten as measured by TEM in bright field mode at 5 keV, wherein the nanowire comprises one or more elements from any of Groups 1 trough 7, lanthanides, actinides or combinations thereof. The preparation of these polycrystalline nanowires involves the use of biological template such as a bacteriophage from the M13 family comprising protein pVIII. Also, an inorganic nanowire comprising one or more metal elements from any of Groups 1 through 7, lanthanides, actinides or combinations thereof and a dopant comprising a metal element, a semi -metal element, a non-metal element or combinations thereof is disclosed and nanowires having core/shell structure are disclosed. Preparation of nanowires in the absence of biological templates is also provided.
