processo para preparar etileno a partir de metano e método para preparar um produto a jusante de etileno

catalisadores em forma de nanofio. a presente invenção provê nanofios úteis como catalisadores heterogêneos. os catalisadores em forma de nanofio são úteis em uma variedade de reações catalíticas, por exemplo, o acoplamento oxidativo de metano para a obtenção de etileno. adicionalmente, são descritos métodos relacionados para o uso e a manufatura destes catalisadores. The invention relates to a method for the preparation of ethylene from methane comprising contacting a mixture comprising oxygen and methane at a temperature below 900 °C with a catalytic nanowire, wherein the catalytic nanowire is 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. The methane is converted by the oxidative coupling of methane (OCM) reaction. The invention relates also to a method for the preparation of a downstream product of ethylene, the method comprising converting methane into ethylene in the presence of a catalytic nanowire and further oligomerizing the ethylene to prepare a downstream product of ethylene, such as gasoline, 1-hexene and/or 1-octene, wherein the catalytic nanowire is 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.
