The first batch of coke oven SCR plants in China generally used medium temperature catalysts(220℃～230℃,Vanadium titanium series)during construction.With the progress of technology,low-temperature catalysts(180℃,Vanadium titanium series)have been widely used.This article focuses on the feasibility,cost,energy-saving benefits,and economic benefits of replacing low-temperature catalysts in the first batch of coke oven SCR units.
