The present invention relates to an installation for depollution of the exhaust gas circulating in an exhaust line (), notably from an internal-combustion engine, comprising at least one catalysis means for selective catalytic reduction of nitrogen oxides (NOx), at least one particle elimination means, a main tank () comprising at least one particle reducing agent and means () for feeding the reducing agent into the exhaust line. According to the invention, the installation comprises reducing agent additivation means ().

Installation for depollution of exhaust gases, particularly of an internal-combustion engines, and method using such an installation

The present invention describes a fluid which is suitable for the decontamination of heat engines which can carry out, at the same time, both the catalytic reduction of oxides of nitrogen (NOx) contained in exhaust gases and assist in the regeneration of the particulate filter (PF). The invention also describes several embodiments of said fluid consisting of producing an oil-in-water type emulsion.

Fluid for purifying heat engines and methods for preparing said fluids by emulsification

The present invention is a method for removing pollution from exhaust gas circulating in an exhaust line () of an internal-combustion engine. The exhaust line comprises an ammonia-sensitive catalyst () with selective NOx catalytic reduction traversed by the gas and an injector () for injecting a reductant of the pollutants The catalyst decomposes the reductant into a hydrogen gas phase and an ammonia gas phase and, for a gas temperature below approximately 150&#xb0; C. injects the hydrogen into the exhaust line in combination with a hydrogen-sensitive NOx catalyst.

Method for depolluting exhaust gas, notably from internal-combustion engines, in particular for motor vehicles, and plant using same

A product for depollution of exhaust gas includes a mixture of an additive for treating particles and a reductant for eliminating nitrogen oxides (NOx). The reductant can contain ammonia or a compound generating ammonia by decomposition, or a hydrocarbon from a hydrocarbon-containing substance, oxygenated or not. The addictive for treating particles can be an additive for catalyzing particle oxidation.
