The main feature of NSTO-1 sulfur resistant deoxidizer is its ability to remove oxygen under high sulfur conditions, which is a pioneering technology in China. This sulfur resistant deoxidizer can be used for the precise removal of oxygen from water gas, coke oven gas, and various chemical feed gases.
Its characteristics are:
1) Wide active temperature range (200~400 ℃);
1) Wide active temperature range (200~400 ℃);
2) Fast reaction speed (airspeed 1000~6000h-1);
3) Strong resistance to sulfate poisoning (sulfur tolerance has no upper limit);
4) Good selectivity, no side reactions such as methanation and CO shift.
