Catalysts for high-temperature decomposition of nitrous oxide – PKR-1, PKR-2, PKR-3<\/h2>

Application<\/h3>

PKR series catalysts are dedicated to the high-temperature decomposition of nitrous oxide(I), (N2O<\/sub>), which is formed during ammonia oxidation. The catalyst bed is placed directly under the ammonia oxidation catalytic grids without the need to reconstruct the ammonia oxidation reactor. <\/p>

Characteristics<\/h3>

The PKR series catalysts (PKR-1, PKR-2 and PKR-3) are precipitate-type systems, and their main components are active iron (III) oxide and aluminum oxide, imparting high mechanical strength.<\/p>

PKR series catalysts are produced in several variants: in the form of tablets (PKR1), cylindrical extrusions of varying diameters (PKR-2) and in the form of thin-walled single-hole rings (PKR-3).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t

Operating parameters<\/h2>
  • Temperature [\u00b0C]: 750 \u00f7 940<\/li>
  • Pressure [bar]: max. 13<\/li>

    Operational advantages<\/h2>
    • High and stable activity to decompose N2O<\/sub>up to 95%,<\/li>
    • High selectivity; the catalyst does not break down nitric oxide (NO) and causes an increase in the conversion rate of NH3<\/sub> to NO,<\/li>
    • Low and stable pressure drops,<\/li>
    • high mechanical strength.<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
