Abstract:
A catalyzed diesel particulate filter (CDPF) and a method for filtering particulates from diesel engine exhaust are provided, where the catalyzed diesel particulate filter includes a substrate and a catalyst composition, where the catalyst composition contains at least one first component, at least one second component, and at least one third component, where the first component is at least one first component selected from the group consisting of cerium and a lanthanide and mixtures thereof, the at least one second component is selected from the group consisting of cobalt, copper, manganese and mixtures thereof; and the third component comprises strontium, where the first component, the second component, and the third component are in an oxide form after calcination. The catalyst on the catalyzed diesel particulate filter lowers the temperature at which particulates are removed from the CDPF by oxidizing the particulates on the filter.

US Patent:
20190338071, Nov 7, 2019
Filed:
Dec 6, 2017
Appl. No.:
16/474616
Inventors:
- Bergen op Zoom, NL
Husnu Alp Alidedeoglu - Newburgh IN, US
Keshavaraja Alive - Mount Vernon IN, US
International Classification:
C08G 63/181
C08G 63/82
B01J 21/06
Abstract:
The present invention relates to a process for the production of a thermoplastic polyester using a reaction mixture comprising a dicarboxylic acid having a melting temperature of ≥200 C. wherein the dicarboxylic acid is introduced to the process in the form of particles having an average particle diameter of ≥100 μm. Such process results in a reduction of the polymerisation time. Furthermore, it allows for the production of thermoplastic polyesters having a desired balance of intrinsic viscosity and carboxylic end group content at a reduced polymerisation time.
