Corporation (OCF) for supporting the pilot-scale evaluation of the catalytic fabric filter concept. Also, the EERC would like to thank Raytheon Engineers & Constructors (RE&C) for their efforts in the completion of Task 4, Conceptual Design and Economic Evaluation, and their overall project technical support. The EERC Project Manager would like to specifically thank Ms. Felixa Eskey (DOE-PETC), Mr. Jack Pirkey (Con Edison), Dr. Aubrey Messing (ESEERCO), Ms. Debra DiMeo (ESEERCO), Dr. Patrick Aubourg (OCF), Ms. Marie Kalinowski (OCF), and Mr. Russ Potter (OCF) for their support and input concerning the catalytic fabric filter evaluation effort. Also, the efforts of Mr. Tony Taladay (RE&C) and Mr. Cameron E. Martin (RE&C) are gratefully acknowledged for their completion of Task 4 and overall project support. The EERC Project Manager, Mr. Greg Weber, would like to thank Mr. Grant Dunham, Mr. Dennis Laudal, Ms. Sumitra Ness, and Mr. Grant Schelkoph for their efforts in completing the various project tasks and contributing to the preparation of this final project report. The authors also gratefully acknowledge the efforts of a large number of EERC support staff who were instrumental in the completion of the experimental work as well as in the preparation of this final project report. Special recognition is due Mr. LeRoy Sbndrol for making the University of North Dakota (UND) steam plant available in support of Subtask 3.4-Fabric Durability Testing/Pulse-Jet System and Mr. Ray Tozer Jr. and the UND steam plant personnel for providing assistance with the day-today monitoring of the baghouse slipstream system operation.

A bench-scale system was constructed at the Energy and Environmental Research Center (EERC) to screen performance of various types of ViTi catalyst-coated, high-temperature, fabric filters manufactured at OwensCorning, Inc.(OCF). This product is targeted for use in utility and industrial facilities for simultaneous NO, and particulate control. Described in this paper are the bench-scale system design, operation, and validation of the data produced.
