A process and system for the precipitation of poly(phenylene ether) is described. Precipitated poly(phenylene ether) obtained by the processes disclosed herein are in the form of poly(phenylene ether) particles having a bulk density of 150 to 500 kg/m, preferably 250 to 500 kg/m.

Process and apparatus for precipitation of poly (phenylene ether)

An exhaust system includes main line that runs through a three way converter (TWC) and then a lean NOtrap (LNT). The exhaust system further includes a bypass line configured to bypass the TWC. The LNT includes catalyst that is non-uniformly distributed along the longitudinal axis. The catalyst is distributed such that storage sites are weighted toward the upstream end of the LNT and oxidation and reduction sites are weighted toward the downstream end of the LNT.

A catalytic converter includes a housing defining an interior space, with a monolith supported therein. The monolith includes a catalyst disposed thereon. The catalytic converter includes a flow directing mechanism defined by one of the housing and/or the monolith to re-direct a flow of exhaust gas across the monolith to obtain a more even flow distribution of exhaust gas across the monolith. The monolith may include different regions, with each region including a different catalyst density disposed thereon. The catalyst density of each region may be optimized for the flow rate of exhaust gas across the monolith through each region.
