Low temperature SCR catalyst is one of the solutions that has been invented to reduce the amount of nitrogen oxide (NOx) emissions in industry and transport sector. It also changes NO x into less harmful nitrogen and water vapor with a catalytic ammonia reaction Its function consists largely of catalysing a reduction in NOx to less dangerous gases by chemical reaction with Ammonia. Some of this catalyst s technical aspects are: Its rather sophisticated constitution, which typically uses metals tungsten and titanium; Stricter performance criteria than many other types available today that require such high injection temperatures or fuel expenses increasing even further over standard truck operations which would hurt the profits of carriers just like these guys remarked about where Urea wouldn't come close The catalyst because of the above lower temperature operating characteristics is able to be used in many fields from power generation equipment to large trucks that need clean air depending on where traditional SCR catalysts will not be very effective as their operation temperature was too high however for this.
