The SCST-233 Spherical Cobalt-Molybdenum Sulfur-Tolerant Shift Catalyst is applicable to large, medium or small-sized synthetic ammonia plants that use coal and oil as raw materials. It can be used in the cuprammonia wash process after high temperature device. And it can also be used in full low temperature shift process replacing the Fe-Cr catalyst. It can replace the Cu-Zn catalyst at low temperature shift device. The SCST-233 catalyst works better with SCST-233K Anti-toxic agent.
