An engine exhaust gas purification device comprising control unit having successively arranged switching device (), counter-current heat exchanger () and at least one exhaust gas purification component (). The switching device () has a first position where a flow path () of the exhaust gas to the exhaust gas purification component () is opened and a second position where a flow path () of the exhaust gas to the exhaust gas purification component () is blocked and the exhaust gas flows along a further flow path () where the exhaust gas is heated and conveyed, via a flow path () of the exhaust gas purification component (), and exits the exhaust gas purification unit () through outlet channels () of the counter-current heat exchanger (). The switching device, the exhaust gas purification component, the counter-current heat exchanger and the flow paths are integrated in a compact exhaust gas treatment unit.

Apparatus and method for purifying exhaust gases for combustion engines

An aqueous polymer dispersion is prepared by reacting at least one olefin in the presence of at least one polymerization catalyst and one emulsifier in an aqueous medium by a process wherein the polymerization catalyst is prepared in an in situ reaction by reacting the ligand compound 2,6-dichloro-para-benzoquinone (Ia) and/or 2,3,6-trichloro-para-benzoquinone (Ib) with a phosphine compound or diphosphine compound and with a metal compound and the polymerization reaction is effected in an aqueous medium.

Method for emulsion polymerizing olefins

The invention relates to a method for monitoring exothermic reactions in a reactor, in which one or more starting materials react exothermically to give at least one product, and at least one gas is present in the reactor during operation as intended or during a runaway, comprising the following process:
