Title:
高いＮＯｘ‐ＳＣＲ変換率及び低いＳＯｘ変換率
Document Type and Number:
Japanese Patent JP6695283
Kind Code:
B2
Abstract:
Articles comprising a catalyst film comprising VOx, MoO3 or WO3, and TiO2 deposited on a substrate are disclosed. The articles are useful for selective catalytic reduction (SCR) of NOx in exhaust gases. Methods for producing such articles deposit a catalyst film on the substrate to form a coated substrate, which is then calcined. When used in an SCR process, the coated articles have enhanced activity for NOx conversion, reduced activity for SOx conversion, or both. Light-weight, coated articles having high catalyst loads can be fabricated at the same or reduced dimensions when compared with laminated articles, and increased kNOx/kSOx ratios are available even from coated articles having relatively thin catalyst films. The articles should have particular value for power plant operations, where coal and high-sulfur fuels are commonly used and controlling sulfur trioxide generation is critical.
