An Experimental Study of Iron Phosphates as Methane CouplingCatalysts

近年来，合成了一类新的甲烷偶联催化剂， 发现于密歇根大学。 这些包括 磷酸铁，其由氧化钒或氧化钒促进。 的 该项目的目的是充分表征这些新的 材料，以促进其进一步发展。 振动光谱学，X射线散射，X射线 光电子能谱和电子探针元素 分析用于确定铁的活性物种 磷酸盐，并优化催化剂和 启动子 这些催化剂作为一种经济手段， 将甲烷转化为液体产品（燃料或化学品 原料）。 他们可能是实用的， 在目前天然气被浪费的偏远地区使用 因为没有运输设施，尽管 收集液体产物。 这类网站的例子包括 阿拉斯加北坡，澳大利亚大堡礁， 阿尔及利亚的沙漠

A new class of methane coupling catalysts has recently been discovered at the University of Michigan. These consist of iron phosphates promoted by molybdena or by vanadia. The purpose of this project is to fully characterize these new materials in order to facilitate their further development. Vibrational spectroscopy, X-ray scattering, X-ray photoelectron spectroscopy, and electron microprobe elemental analysis are used to determined the active species of iron phosphate and to optimize the relation between catalyst and promoter. These catalysts how great promise as an economical means to convert methane to liquid products (fuels or chemical feedstocks) under mild conditions. They may be practical for use at remote sites where natural gas is presently wasted because facilities to transport it are unavailable, although liquid products are collected. Examples of such sites are the North Slope of Alaska, the Australian Barrier Reef, and the desert fields of Algeria.
