  • Patent number: 8586496
    Abstract: A method is described for preparing a molecular sieve-containing catalyst for use in a catalytic process conducted in a stirred tank reactor. The method comprises providing a mixture comprising a molecular sieve crystal and forming the mixture into catalyst particles having an average cross-sectional dimension of between about 0.01 mm and about 3.0 mm. The mixture may include a binder and the catalyst particles are then calcined to remove water therefrom and, after calcination and prior to loading the catalyst particles into a reactor for conducting the catalytic process, the catalyst particles are coated with a paraffin inert to the conditions employed in the catalytic process.

  • Patent number: 8507404
    Abstract: Provided are improved regenerable SOx trap formulations for on-board vehicle applications. The regenerable sulfur trap formulations reduce the rate of sulfur poisoning of a downstream nitrogen storage reduction (NSR) catalyst trap in exhaust gas cleaning systems for combustion engines by adsorbing SOx as metal sulfate under lean exhaust conditions and desorbing the accumulated SOx under rich exhaust conditions. The regenerable sulfur oxides trap catalyst compositions include a metal (M) oxide, wherein M is selected from Cu, Fe, Mn, Ag, Co and combinations thereof and a metal (M)-La—Zr oxide, wherein M is selected from Cu, Fe, Mn, Ag, Co and combinations thereof. In addition, provided are improved exhaust gas cleaning systems and methods for treating exhaust gas from a combustion source that include a hydrogen generation system, a regenerable sulfur oxides trap, and a regenerable nitrogen storage reduction (NSR) catalyst trap.

  • Patent number: 8409518
    Abstract: A sulfur tolerant oxidation catalyst with appreciable NO and HC oxidation capabilities has been developed for use in any component of an exhaust aftertreatment system for a lean-burn engine where the oxidation of at least NO is desired. Several non-exclusive examples of such components where the oxidation catalyst may be employed include a DOC and a LNT. The oxidation catalyst may comprise perovskite oxide particles that support palladium particles. The ability of the palladium supported perovskite oxide particles to concurrently oxidize NO and HC's can significantly diminish or altogether eliminate the use of platinum in the exhaust aftertreatment system for at least NO oxidation. The oxidation catalyst, moreover, may exhibit superior thermal durability and better NO and HC oxidation activities than platinum in some instances.
