This SBIR Phase I project will develop a method that utilizes a carbon based adsorptive surface flow membrane to perform continuous concentration of methane from raw bio-gas from large animal feed operations. The membrane can upgrade biogas at 40 to 65% CH4 to 90%+ CH4 with 10% CO2 at minimal/no pre-compression. Then, the upgraded methane can be used to generate pipeline quality methane, to produce peak time electrical power from on-site gas storage tanks for resale to the grid and/or to generate power or heat for in-house use. The resulting methane can be used on site, supplied via pipeline after being pressurized, or be feed to an on site electrical generating plant.The broader/commercial impact of the project will be first to reduce the release of the greenhouse gas methane, second to produce a stream of high quality natural gas at a theoretically lower cost than competing technologies.

SBIR一期项目将开发一种方法，利用碳基吸附表面流膜，从大型动物饲料生产的原料沼气中连续浓缩甲烷。该膜可以在最小预压缩或不预压缩的情况下，将CH4含量为40 - 65%的沼气提升到90%+ CH4和10% CO2的沼气。然后，升级后的甲烷可以用来产生管道质量的甲烷，从现场的储气罐中产生高峰时间的电力，转售给电网，或者产生电力或热量供室内使用。产生的甲烷可以在现场使用，经过加压后通过管道供应，或者进入现场发电厂。该项目的广泛/商业影响将首先减少温室气体甲烷的排放，其次以理论上比竞争技术更低的成本生产出高质量的天然气。
