SHELL CATALYTIC CONVERTER MADE OF A HOLLOW CYLINDRICAL CARRIER BODY AND A CATALYTICALLY ACTIVE OXIDE MASS APPLIED TO THE OUTER SURFACE OF THE CARRIER BODY

摘要

The present invention relates to a hollow cylindrical carrier having a length of from 2 to 10 mm, an outer diameter of from 4 to 10 mm and a wall thickness of from 1 to 4 mm, and a catalyst active oxide material / RTI Formula 1 In the above formula, the variables have the following meanings: X ¹ = at least one of an alkali metal and an alkaline earth metal; X ² = at least one element from the group consisting of Si, Al, Ti and Zr; And n = stoichiometric coefficient of elemental oxygen, determined by stoichiometric coefficients of elements other than oxygen in formula (1) and their charge.
