This Small Business Technology Transfer (STTR) Phase I project is based on a novel separation concept: push/pull adsorption. The presently available technologies for producing oxygen are cryogenic distillation and pressure swing adsorption, both of which use pressure-volume work. With either of these technologies oxygen typically costs $40/ton for industrial scale production with most of this cost going for electrical energy. Because push/pull adsorption replaces electrical energy with steam, it has much lower energy and dollar costs. Push/pull adsorption has the further advantage of being suitable for small-scale oxygen production. A major reduction in the cost of oxygen will be of immediate benefit to steel making, glass manufacturing, and all the other industries in which oxygen is used. Cheaper oxygen would also make it practical to produce gasoline and other fuels from coal via the Fischer-Tropsch process, ending America's dependence on foreign oil.

这个小型企业技术转让（STTR）一期项目是基于一种新的分离概念：推/拉吸附。目前可用的制氧技术有低温蒸馏和变压吸附，两者都采用压力-体积功。这两种技术中的任何一种，在工业规模生产中，氧气的成本通常为每吨40美元，其中大部分成本用于电能。因为推/拉吸附用蒸汽代替电能，所以能耗和成本都很低。推/拉吸附法的另一个优点是适用于小规模的氧气生产。氧气成本的大幅降低将对炼钢、玻璃制造和所有其他需要氧气的工业产生直接的好处。更便宜的氧气也将使通过费托法从煤中生产汽油和其他燃料成为可能，从而结束美国对外国石油的依赖。
