美国Siluria科技公司于2010年12月10日宣布,开发出一种合成方法,可调整催化剂表面的形态,从而可在低温下使甲烷氧化偶联(OCM)反应具有高的性能。工业上可行的OCM方法已探索了几十年,但过去的努力均未成功,这是由于使甲烷活化需要的高温降低了反应的选择性。采用以前研究过的许多催化剂,甲基自由基团在转化为所需的乙烯产品之前,就滞留在催化剂表面,
United States Siluria Technologies announced on December 10, 2010 that it has developed a synthetic approach that regulates the morphology of the catalyst surface to provide high performance at low temperature for the oxidative coupling of methane (OCM) reaction. The industrially viable OCM method has been explored for decades, but none of the past efforts have been successful due to the reaction selectivity being lowered by the high temperatures required for the activation of methane. With many of the catalysts previously studied, methyl free radicals remain on the catalyst surface before conversion to the desired ethylene product,
