美国和外国政府强制要求对运输燃料（汽油、柴油和喷气燃料）进行深度脱硫，这也是未来燃料电池应用所需要的。然而，以现有技术实现这一目标极其困难且成本高昂，需要在高压和高温下运行的催化反应器。我们表明，Cu+ 和 Ag+ 沸石 Y 可以在环境温度和压力下选择性地吸附商业燃料中的硫化合物，并且具有高硫容量（通过 pi 络合）。因此，硫含量从 430 降低到
Deep desulfurization of transportation fuels ( gasoline, diesel, and jet fuels) is being mandated by U. S. and foreign governments and is also needed for future fuel cell applications. However, it is extremely difficult and costly to achieve with current technology, which requires catalytic reactors operated at high pressure and temperature. We show that Cu+ and Ag+ zeolite Y can adsorb sulfur compounds from commercial fuels selectively and with high sulfur capacities (by pi complexation) at ambient temperature and pressure. Thus, the sulfur content was reduced from 430 to
