An exhaust gas cleaner comprising a catalyst carried on a heat-resistant ter, the catalyst comprising (a) one or more alkali metals, (b) one or more metals selected from the group consisting of Zn, Sn and transition metals excluding platinum-group metals, and (c) one or more rare earth metals, and a method of cleaning an exhaust gas with it. Alkali metals may be added to a fuel.

Method of cleaning an exhaust gas containing nitrogen oxides and fine

An exhaust gas cleaner comprising a catalyst carrier on a heat-resistant filter, the catalyst comprising (a) one or more alkali metals, (b) one or more metals selected from the group consisting of Zn, Sn and transition metals excluding platinum-group metals, and (c) one or more rare earth metals, and a method of cleaning an exhaust gas with it. Alkali metals may be added to a fuel.

Catalyst for cleaning exhaust gas

A volatile chlorine-containing organic compound, e.g., trichloroethylene and tetrachloroethylene, contained in a vent gas as a pollutant of atmospheric air can be rapidly and efficiently decomposed into less harmful decomposition products by irradiating the vent gas with ultraviolet light having a wavelength of 400 nm or shorter while the vent gas is in contact with a titanium dioxide powder, for example, supported on the wall of a reactor through which the vent gas is passed.
