摘要： PROBLEM TO BE SOLVED: To reduce a water requirement for the removal of an acidic gas contained in a PFC decomposition exhaust gas and the cooling of exhaust gas, thereby diminishing the environmental load. SOLUTION: This method of treating an exhaust gas comprises a wet removal process to remove a water-soluble gas contained in a gas to be treated containing PFC, a gas decomposition process to decompose the PFC gas in the latter part of the wet removal process, and an acidic gas removal process to remove an acidic gas generated by the decomposition of the PFC, in the latter part of the gas decomposition process. In addition, the method comprises a moisture condensation process to condense the moisture of the gas to be treated, in the first part of the acidic gas removal process. That is, the acidic gas contained in the gas is dissolved in a condensate generated by condensing the water vapor contained in the PFC decomposition exhaust gas, and then the complete removal of the acidic gas is achieved by adding a neutralizing agent into the exhaust gas.

摘要： PROBLEM TO BE SOLVED: To suppress deterioration of exhaust gas purification capability of an exhaust gas purification catalyst containing an alkali metal or an alkaline earth metal on a Cr-containing substrate because of cracking of the substrate caused by a migration of Cr of the substrate to the catalytic active component side and reaction of Cr with the alkali metal or alkaline earth metal.
SOLUTION: A Cr-trapping material is formed while being brought into contact with the constituent component of the Cr-containing substrate. As the Cr-trapping material is used an element having basicity stronger than the alkali metal or alkaline earth metal to be used as the catalytic active component or Ag. Since the migration of Cr in the substrate is inhibited by the Cr-trapping material, migration of Cr to the catalytic active component and reaction of Cr with the alkali metal or alkaline earth metal can be suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a NOx concentration measuring method capable of measuring accurately the NOx concentration in exhaust gas, and a deterioration diagnosis method and a device of an NOx purification catalyst. SOLUTION: A sensor element constituted of a catalyst capable of capturing NOx generated by oxidizing NO in a lean atmosphere and NOx existing in the exhaust gas and reducing NOx in a stoichiometric or rich atmosphere, and of a temperature measuring means of the catalyst are provided in an internal combustion engine exhaust gas passage where exhaust gas having a lean air-fuel ratio and exhaust gas having a rich or stoichiometric air-fuel ratio enter alternately, and the NOx concentration in the lean exhaust gas is determined by using the sensor element from a catalyst temperature rising degree caused by an NOx reduction heat by reductive gas when the air-fuel ratio of the exhaust gas is changed from the lean side to the rich side, and a space velocity of the exhaust gas. The NOx quantity captured by the catalyst at the lean time can be determined by installing the sensor elements on the front and the back of the NOx purification catalyst, and deterioration diagnosis of the lean NOx purification catalyst can be performed.
