H2 Selective Catalytic Reduction (SCR) System

This student team will work to investigate selective catalyst reduction technology that uses H2 as a reducing agent to selectively reduce NOx produced by H2 combustion to N2 and H2O. This student team will work to use available scientific literature on the topic to understand current status and trends for H2 SCR. This student team will work to conduct research aimed at developing knowledge and will work to produce a paper study that explores existing technology in the H2 SCR space. This student team will work to deliver on the following: - Investigate difference in substrate use, metal used for ion, wash coat. - Understand change in space velocity due to increased reaction rates. This student team will work to illustrate an understanding of the status of H2 SCR technology and current paths under investigation that show promise. This student team will work to achieve the following outcomes: Work to identify what is the current selectivity of H2 SCR. Work to define the current temperature range of H2 SCR. Work to identify the by products of H2 SCR with H2 combustion exhaust. Work to identify the washcoats in use with H2 SCR. Work to identify the metal(s) in use with H2 SCR. This student team will also work to explore how using H2 differs from using ammonia in terms of temperature.
