How can we reduce nox
WebThe Catalytic Control of Nitrogen Oxide Emissions. Catalytic control of nitrogen oxides can be achieved by two methods, known as non-selective catalytic reduction (NSCR) and selective catalytic reduction (SCR). NSCR uses hydrogen, carbon monoxide or hydrocarbons as the reducing agent ( 14 ), while SCR employs ammonia; both routes … WebHá 3 horas · Here’s the bad news: Forever chemicals are everywhere.
