Abstract
The invention provides a process for purification of an exhaust gas comprising nitrogen oxides, carbon monoxide, hydrocarbons and particulate matters from an internal combustion engine comprising the step of contacting the exhaust gas with one or more catalysts on one or more cross corrugated wire mesh sheets () being arranged between two or more gas impermeable cross corrugated sheets (). The exhaust gas is contacted with one or more catalysts being coated in different zones on the one or more cross corrugated wire mesh sheets (). Particulate matters in the exhaust gas are retained in a zone of the gas impermeable sheets (), where the zone is porous and optionally coated with an oxidation catalyst. The exhaust gas from the combustion engine can be heated by the purified exhaust gas. The invention further comprises an apparatus for the purification process of an exhaust gas from an internal combustion engine.
