  1. 1. PILCs for trapping phosphorus in a heavy duty engine exhaust system : An experimental evaluation of the phosphorus sorption capability of different clay materials

    University essay from Uppsala universitet/Strukturkemi

    Author : Anders Kvarned; [2016]
    Keywords : PILC; PCH; phosphorus sorption; exhaust treatment; catalyst poisoning;

    Abstract : In order to fulfil the requirements in the EURO VI standard, regulating emissions from heavy duty vehicles, the exhaust aftertreatment system needs to maintain its efficiency for at least seven years or 700 000 km. In diesel applications the diesel oxidation catalyst (DOC) is located closest to the engine and is thus the most vulnerable to poisoning contaminants, such as phosphorus originating from fuel and oil additives, which deactivates the catalyst.

    Author : Alexander Ekström; Olof Gustafsson; Anders Kvarned; Elinor Löf-Nilsson; Sebastian Proper; Markus Sköld; Pär Snögren; Oscar Ullsten; [2014]
    Keywords : aerogel; pore size; crush-test; mechanical properties; Quartzene; density; microstructure; fracture;

    Abstract : In this project the relation between pore size/porosity and the mechanical properties has been studied in the aerogel-like material Quartzene®. Quartzene® is a patented material produced by Svenska Aerogel AB. Density measurements were made on three different types of Svenska Aerogels ABs Quartzene® in the shape of pellets. READ MORE
