This PFI: AIR Technology Translation project focuses on translating novel catalytic oxidation technology based on the "pore-flow reactor" (PoFR) concept together with an ultra-violet (UV)-photodecomposition-based (PhoR) technology for the removal of siloxanes, a particularly problematic class of impurities found in biogas and landfill gas (LFG). This technology addresses the need for the development of a novel clean-up method to remove toxic contaminants from these important renewable fuels. The project will result in the completion and the validation of the proof-of-concept both at the lab-scale and the field-scale of this landfill gas and biogas clean-up technology. This LFG and biogas clean-up system has the following unique features: (i) it completely destroys the toxic contaminates rather than transfer them into a different medium; (ii) it does not require the use of adsorption media and their regeneration or the flaring of desorbed contaminants; (iii) it is a continuous process. These features provide process performance, reliability, safety, environmental and cost savings advantages when compared to the leading competing adsorption/absorption technologies in this market space. The preliminary results, so far, with the LFG/biogas clean-up technology are promising. This project addresses technology gaps as it translates from research discovery toward commercial application, specifically: (i) gaining a better insight about the characteristics of each individual technology subsystem (PoFR and PhoR), but also how they potentially function together as an integrated technology; (ii) acquiring a better understanding of the reaction/transport processes that occur during contaminant destruction; (iii) developing an effective process model to be able to optimize performance without the need of extensive and costly experimentation; (iv) field-testing of the technology to validate its ability to function with real LFG and biogas; (v) process modeling to demonstrate process feasibility The project engages three principal partners, the University of Southern California (USC) and two small US companies, Media and Process Technology, Inc. of Pittsburgh, PA (M&PT), and GC Environmental, Inc. of Anaheim, CA (GCE) working as a team to develop this novel cost-effective clean-up method to remove toxic contaminants from LFG and biogas. The project will engage three additional broader-context partners, namely the EISGTTP Program at San Diego State University (guiding commercialization aspects), and a small business (BENA) and Southern California Gas Company (SoCalGas), both providing test environments, all working together towards a common goal of the translation of this technology from research discovery toward commercial reality.This novel clean-up technology is important because it will allow LFG and biogas to gain their full potential as renewable fuels; it also shows promise for widespread application, beyond the LFG/biogas market, for volatile organic compounds (VOC) destruction in contaminated gas streams, encountered in many energy and industrial applications. This technology will contribute to the U.S. competitiveness in the renewable energy and environmental fields by providing superior treatment capability allowing engines, combustion and process equipment to experience longer life with less maintenance.

该PFI：AIR技术翻译项目的重点是翻译基于“孔流反应器”（PoFR）概念的新型催化氧化技术，以及用于去除硅氧烷的紫外线（UV）-光分解（PhoR）技术，硅氧烷是沼气和填埋气（LFG）中发现的一类特别有问题的杂质。该技术解决了开发一种新的清洁方法以从这些重要的可再生燃料中去除有毒污染物的需求。该项目将完成并验证这一填埋气和沼气清洁技术的实验室规模和现场规模的概念验证。该LFG和沼气净化系统具有以下独特的特征：（i）它完全破坏有毒污染物，而不是将它们转移到不同的介质中;（ii）它不需要使用吸附介质及其再生或燃烧解吸的污染物;（iii）它是一个连续的过程。与该市场领域领先的竞争吸附/吸收技术相比，这些功能提供了工艺性能，可靠性，安全性，环境和成本节约优势。到目前为止，LFG/沼气净化技术的初步结果是有希望的。该项目解决了从研究发现到商业应用的技术差距，具体而言：（i）更好地了解每个技术子系统的特征（PoFR和PhoR），而且还包括它们如何作为一种综合技术潜在地共同发挥作用;（二）更好地了解污染物销毁过程中发生的反应/迁移过程;（iii）开发一种有效的工艺模型，以便能够优化性能，而不需要进行大量和昂贵的实验;（iv）对该技术进行实地测试，以验证其使用真实的填埋气体和沼气的能力;（v）建立流程模型，以证明流程的可行性该项目有三个主要合作伙伴，南加州大学（USC）和两家美国小公司，媒体和过程技术公司。（Pittsburgh，PA（MPT））和GC Environmental，Inc.的阿纳海姆，加利福尼亚州（GCE）作为一个团队，开发这种新的成本效益的清理方法，以消除有毒污染物的垃圾填埋气和沼气。该项目将与另外三个更广泛的合作伙伴合作，即圣地亚哥州立大学的EISGTTP项目（指导商业化方面），以及小企业（BENA）和南加州天然气公司（SoCalGas），两者都提供测试环境，所有人都朝着一个共同的目标努力，将这项技术从研究发现转化为商业现实。垃圾填埋气和沼气技术非常重要，因为它将使垃圾填埋气和沼气获得其作为可再生燃料的全部潜力;除了垃圾填埋气/沼气市场之外，它还显示出广泛应用的前景，用于在许多能源和工业应用中遇到的污染气体流中的挥发性有机化合物（VOC）的破坏。这项技术将有助于美国在可再生能源和环境领域的竞争力，提供上级处理能力，使发动机，燃烧和工艺设备经历更长的寿命和更少的维护。
