Foreword

Instead of the standard YS/T 210-1994 "Diesel exhaust gas purifying spherical platinum catalyst." Compared with this standard YS/T 210-1994, the main changes are as follows. --- The specific surface area of the carrier by a 7m2/g ~ 12m2/g upgraded to ≥80m2/g; --- Will be under positive pressure by the strength 20Kgf/pcs modify ≥196N/teeth; The bulk density of the --- 1.0 ± 0.05kg/L to 600g/L ~ 1000g/L; --- Add to hydrocarbon purification temperature and purification rate requirements; --- New regulations the maximum conversion rate of carbon monoxide requirements; --- Starting temperature of the purification of carbon monoxide by 90% claim to no higher than 270 ℃ is not higher than 260 ℃; --- Modify vector determination method specific surface area; --- Provisions of the catalytic activity evaluation methods. Appendix A of this standard is a normative appendix. This standard by the National Standardization Technical Committee of non-ferrous metals and centralized. This standard was drafted. Kunming Institute catalyst limited liability company, your research Platinum Limited. The main drafters of this standard.
