Self-Regenerating Particle Trap for Emission Control:Self-Regenerating Particle Trap (ST6867-1)

Rochester Institute of Technology


Power generation systems and vehicle engines are being subjected to increasing regulatory control over air emissions. For instance, new "Tier II" standards being implemented by the Environmental Protection Agency over the next six years will impose much more stringent controls on exhaust emissions and present a challenge to both fuel suppliers and engine/system manufacturers and control equipment suppliers. Control of particulate matter (PM) emissions represents a major technical barrier. At the present time, a device that is robust, efficient, durable, packageable, and maintenance-free is not available for the elimination of PM. The Rochester Institute of Technology has developed a promising concept for an efficient, self-regenerating particulate trap for engine emissions control, based on the adaptation of a non-thermal, plasma assisted catalytic reduction of exhaust gases using a corona discharge technique.

Project Description

Develop and evaluate a device that will trap particulate matter in the emissions of engine driven generators using petroleum products, coal and natural gas by using the combination of non-thermal plasma oxidation and emissions catalyst technologies. The device will have a low pressure drop to maximize the efficiency, and it also will be designed to be self-regenerating. The project will consist of furthering the initial laboratory scale research and technology development conducted to date to optimize the corona device probe, fabricate an improved prototype, test the prototype in conjunction with the NYS DEC, and produce a full manufacturing prototype. Project tasks will also include establishing manufacturing costs and development of a commercialization plan.


The public and the environment are the groups that stand to reap the benefits of this proposal. The proposed device could reduce as much as 110,000 tons of particulate emissions per year. This device is also being designed for both power generation and automotive applications.

Project Results

The project was successfully completed and the technology licensed to a spinoff startup company, Energy and Environmental Technologies, Inc., led by the RIT professor involved in developing the technology
