METHOD OF REGENERATING SCR CATALYST

摘要

A method for regenerating the SCR(Selective Catalyst Reduction) catalyst is provided to recover the performance of the catalyst before the contamination. A spent catalyst for an SCR is washed in a formic solution. The catalyst washed by the formic solution is dried at 100 to 120 degrees, and the dried catalyst is fired at 600 degrees or less. The density of the formic solution is 0.1M to 1M. The catalyst for the SCR is honeycomb type.
