中文摘要： 沼气经过除硫除CO2除水等一系列净化和提纯处理后可达到管道天然气和车用天然气的标准，从而代替天然气使用，在一定程度上缓解燃料紧张和化石燃料造成环境污染的问题。 我国生物质资源丰富，但在沼气利用方面还只是简单的初级利用，高品质沼气的制取和应用实践还处于探索阶段。本研究以沼气中各成分的物理和化学性质的差异为依据，采用加压水洗与吸附相结合的方法，进行沼气纯化制备车用燃料的研究，阐明吸附性填料在水洗中的作用原理，揭示特殊填料存时下沼气在多相流中气体分离的机理，为研究开发适合我国国情的 沼气纯化工艺提出新思路，为沼气的净化、提纯和高端利用奠定基础，为沼气产品品质提升和应用范围拓展提供参考。

英文摘要： After desulfurization, decarburization and dehydration, upgraded biogas could reach the standards of pipe natural gas and compressed natural gas for vehicle. Upgraded biogas substitute natural gas could be useful for easing the problem of fuel shorting and environment pollution. There are plentiful bioresource in china, but the usage of biogas is still in simple and low-level, the study on the production and utilization of upgraded biogas are in the stage of exploration. This study research biogas upgrading for vehicle fuel on the foundations of the difference of physical and chemical properties among all ingredients in biogas, by the method of pressured water scrubbing combine with absorpting. The study will clarify the theory of gas separating in multiphase flow and the action principle of adsorption packings during biogas water scrubbing, put forward new ideas for develop biogas upgrading technology suitable for china, lay foundations for biogas purification, enriching and high-level utilization, and supply references for promote biogas production quality and develop its application.
