This system employs carbon-based catalytic desulfurization coupled with ultra-low temperature (90–180 ℃ ), achieving directional catalytic oxidation of SO2 to H2SO4 and NH3-SCR denitrification (NOx → N2) for near-zero multi-pollutant emissions without additional CO2, simultaneously producing industrial dilute sulfuric acid. Using graded conditioning-adsorption catalysis-resource co-production processes, it integrates dedicated catalysts, modular reaction tower groups, and intelligent control platforms, featuring >95% sulfur conversion and 50% lower operating costs.
