continuous diesel soot control with minimal back pressure loss using conventional flow substrates and active direct soot oxidation catalyst disposed on them

摘要

Catalysts for the direct catalytic oxidation of diesel particulate matter are disclosed. The catalysts relate to OIC/OS materials having a stable cubic crystal structure, and most especially to promoted OIC/OS wherein the promotion is achieved by the post-synthetic introduction of non- precious metals via a basic (alkaline) exchange process.
