  • Diesel oxidation catalyst having a capture region for exhaust gas impurities
    Patent number: 10155197
    Abstract: An oxidation catalyst is described for treating an exhaust gas produced by a diesel engine, wherein the oxidation catalyst comprises: a substrate; a capture material for capturing at least one phosphorus containing impurity and/or at least one sulfur containing impurity in the exhaust gas produced by the diesel engine; and a catalytic region disposed on the substrate; wherein the catalytic region comprises a catalytic material comprising a platinum group metal (PGM) selected from the group consisting of platinum (Pt), palladium (Pd) and a combination of platinum (Pt) and palladium (Pd).
    Type: Grant
    Filed: November 30, 2016
    Date of Patent: December 18, 2018
    Assignee: Johnson Matthey Public Limited Company

  • Diesel oxidation catalyst having a capture region for sulfur containing impurities
    Patent number: 10137413
    Abstract: An oxidation catalyst is described for treating an exhaust gas produced by a diesel engine. The oxidation catalyst comprises: a substrate; a capture material for capturing at least one sulfur containing impurity in the exhaust gas produced by the diesel engine; wherein the capture material comprises a metal for reacting with an oxide of sulfur in the exhaust gas and particles of a refractory oxide, wherein the particles of the refractory oxide have a mean specific surface area ?50 m2/g; and a catalytic region disposed on the substrate; wherein the catalytic region comprises a catalytic material comprising a platinum group metal (PGM) selected from the group consisting of platinum (Pt), palladium (Pd) and a combination of platinum (Pt) and palladium (Pd).
