Description:
Automotive three-way catalysts (TWC) are efficient at steady state operating temperatures typically destroying over 98% of incoming hydrocarbons (HCs) and carbon monoxide (CO). However, up to 80% of emissions occur during the first few minutes of Federal Test Procedures (FTP) when the engine is running rich, the engine is cold, and TWC has not reached light-off temperature. This project's objective is to develop and demonstrate that compact oxygen enrichment membranes can be effectively used to significantly reduce HC and CO emissions during start-up and lead to quicker heat-up of TWC. It Phase I, they showed that:1. Membranes with 5 times goal performance were developed and demonstrated stable performance.
2. Economic analysis indicated membrane modules supplying 1500 scfh would weigh two pounds, occupy 0.13 cubic feet, and cost about $17.50.
3. Oxygen enrichment significantly reduced HC/CO start-up emissions.
In Phase II, they will: 1) design, build and test full scale membrane modules; 2) install membrane modules in automobiles and demonstrate reduced cold-start emissions via FTP; and 3) run extensive membrane module tests in engine environment.
