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

9561260 Lavid这个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，能够将现有的消耗臭氧层物质库存转化为无害环境和具有商业价值的产品。现有的氟氯化碳库存对平流层臭氧层的消耗构成严重威胁。用替代材料替代它们将带来重大的处理挑战。目前，还没有经济上可行、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起始与氢还原气氛的协同效应，促进链传播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有代表性的氟氯化碳转化为理想的氢氟碳化合物和/或单体，从实验上证明可行性。为了实现这一目标，使用了一个四任务研究计划。它包括：(1)设计和建造一个特殊的光化学流动反应器，(2)实验演示，(3)动力学建模，(4)成本估算。该项目将产生一种“绿色”技术，将消耗臭氧层物质无害地转化为具有商业价值的产品。目前估计有45亿磅的氯氟烃库存，这构成了一个严重的处置问题，将成为生产高价值产品的重要原料。根据初步的成本估计，现有的库存构成了巨大的环境负担，可转化为价值约40亿美元的可销售产品。

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.
