Contaminated ground water treatment is most economically accomplished by air stripping followed by complete catalytic combustion. For hydrocarbon sources from underground gasoline storage, the catalytic combustors are now being deactivated by contaminants such as lead. Poison tolerant catalyst designs are needed to prevent inactivation of the converter. The proposed research focuses on the development of a poison tolerant system to handle leaded gasoline contaminated ground water. The program exploits the use of a special guard bed combined with design and control strategies to reduce the impact of deactivation. Mathematical modeling of the process together with measurements taken during the deactivation process of a commercial catalyst will lead to a guard bed feasibility demonstration. Successful completion of this research project could have a significant impact on the technology used to eliminate contaminants from ground water and industrial waste streams. Catalytic conversion of the unwanted hydrocarbons could become the preferred technique for ground water cleanup if catalyst poisoning is controlled.

污染地下水处理最经济的方法是空气剥离，然后进行完全催化燃烧。对于地下汽油储存的碳氢化合物来源，催化燃烧器现在被铅等污染物停用。为了防止转炉失活，需要设计耐毒催化剂。提出的研究重点是开发一种耐毒系统来处理含铅汽油污染的地下水。该方案利用特殊保护床，结合设计和控制策略，减少失活的影响。该过程的数学建模以及在商业催化剂失活过程中进行的测量将导致防护床的可行性论证。这项研究项目的成功完成可能会对用于消除地下水和工业废水中的污染物的技术产生重大影响。如果催化剂中毒得到控制，不需要的碳氢化合物的催化转化可能成为地下水净化的首选技术。
