1. Purpose
TO-3 precious metal catalyst is a new type of catalyst developed by our center for the removal and purification of H2and O2in high concentration CO gas, based on the successful industrial application of TH-2 and TH-3 series precious metal catalysts. It uses modified catalyst carriers and special additives. This catalyst has the characteristics of good selectivity, high low-temperature activity, high removal efficiency (O2<10ppm), good anti toxicity and thermal stability, and long service life.
TO-3 selective deoxygenation catalyst is mainly used for selective removal and purification of trace amounts of H2and O2in coal gas, synthesis gas, and high concentration CO feed gas.
