T2001-035 Preparation and use of a catalyst for the reduction of nitric oxide.

The Need

Nitrogen oxide (NOx) reduction with hydrocarbons has recently attracted attention due to stricter environmental regulations. Pollution of the atmosphere by NOx emission from combustion sources continues to be a major environmental concern. Using methane as a reducing agent has advantages such as its low cost and abundant availability in natural gas. There have been numerous studies in the literature on NOx reduction over ZSM-5 supported and zeolite supported catalysts using hydrocarbons including methane. A catalyst for the reduction of NOx would be useful in a number of applications.

The Technology

Researchers at the Ohio State University, led by Dr. Umit Ozkan, have developed a supported catalyst, comprising an active and a promoter metal, that reduces nitrogen oxides (NOx) with a lower hydrocarbon. The support, titanium dioxide, may contain activated carbon. The promoter metals are chosen from the lanthanide metals and the active metals are either palladium or platinum.

Commercial Applications

  • Power plants
  • Gas turbines
  • Industrial processing units
  • Car exhausts

Benefits/Advantages

  • Reduces nitrogen oxides with a lower hydrocarbon
  • More efficient than previous process
