SBIR Phase I: Photochemical Process for Transformation of Ozone-Depleting Substances Into Environmentally Benign and Commercially Valuable Products

小行星9561260 这一小企业创新研究第一阶段项目将开发一种创新的光化学工艺，能够将现有的臭氧消耗物质库存转化为无害环境和具有商业价值的产品。现有的氯氟化碳库存对平流层臭氧层的消耗构成严重威胁。用替代材料替换它们将带来重大的处置挑战。目前，还没有经济上可行和环境上可接受的技术。该项目提供了一种独特的解决方案，称为光氢脱氯（PHD）。它是基于W引发与氢气还原气氛相结合的协同效应，促进链增长反应并导致所需产物的高选择性。该项目的主要目标是通过有效地将代表性的氟氯化碳转化为所需的氢氟碳化合物和/或单体来实验证明其可行性。为了实现这一目标，使用了四个任务的研究计划。它包括：（1）特殊光化学流动反应器的设计和建造，（2）实验演示，（3）动力学建模，和（4）成本估算。 该项目将带来一种“绿色”技术，用于将臭氧消耗物质环境安全地转化为具有商业价值的产品。目前估计有45亿磅的氟氯化碳库存，造成了严重的处置问题，将成为生产高价值产品的重要原料。根据初步的成本估计，现有的库存，这是一个巨大的环境责任，可以变成大约40亿美元的可销售的产品。

9561260 Lavid This Small Business Innovation Research Phase I project will develop an innovative photochemical process capable of transforming existing stockpiles of ozone-depleting substances into environmentally benign and commercially valuable products. Existing stockpiles of chlorofluorocarbons (CFCs) pose a serious threat to the depletion of the stratospheric ozone layer. Their replacement with alternative materials will cause a significant disposal challenge. Currently, there is no economically practical and Environmentally acceptable technology. This project offers a unique solution designated, Photo-HydroDechlorination (PHD). It is based on a synergistic effect of W initiation combined with a reducing atmosphere of hydrogen, promoting chain-propagation reactions and leading to high selectivity of desired products. The primary objective of project is to experimentally demonstrate feasibility by efficiently transforming representative CFCs into desirable hydrofluorocarbons (HFCs) and/or monomers. To accomplish this objective, a four-task research plan is used. It includes: (1) design and construction of a special photochemical flow reactor, (2) experimental demonstration, (3) kinetic modeling, and (4) cost estimates. This project will lead to a "green" technology for environmentally safe transformation of ozone-depleting substances into commercially valuable products. The current stockpile of an estimated 4.5 billion pounds of CFCs, which poses a serious disposal problem, will become a vital feedstock to produce high value products. Based on preliminary cost estimates, the existing stockpile, which represents a huge environmental liability, can be turned into about $4 billion of saleable products.
