| 英文摘要 | Monolith SCR catalysts coated with V2O5-WO3/TiO2 were prepared by varying binder and coating thickness. Comparing with a monolith extruded with 100% V2O5-WO3/TiO2 powder, a coated monolith with a catalyst-coating layer of 260 A mu m in thickness exhibited the similar initial NO (x) reduction activity at 250A degrees C. After 4 h abrasion (attrition) in an air stream containing 300 g center dot m(-3) fine sands (50-100 A mu m) at a superficial gas velocity of 10 m center dot s(-1), the catalyst still has the activity as a 100% molded monolith does in a 24-h activity test and it retains about 92% of its initial activity at 250A degrees C. Estimation of the equivalent durable hours at a fly ash concentration of 1.0 g center dot m(-3) in flue gas and a gas velocity of 5 m center dot s(-1) demonstrated that this coated monolith catalyst is capable of resisting abrasion for 13 months without losing more than 8% of its initial activity. The result suggests the great potential of the coated monolith for application to de-NO (x) of flue gases with low fly ash concentrations from, such as glass and ceramics manufacturing processes. |
