Properties of Ti-Pomoted Sulfur-tolerant CO Shift Catalyst
Abstract:
The Ti-promoted sulfur-tolerant water-gas-shift catalyst has been studied in micro-reactor system as function of activity and anti hydration by using TPR、SEM、XRD、IR techniques. The results show that an appropriate amount of TiO2 in the carrier of catalyst can transform much more number of the inactive Mo6+ in the catalyst into the active ones such as Mo5+ and Mo4+, obviously increasing the catalytic activity. Meanwhile, the strength of L-acid absorption sites on the surface of the Al2O3 can be effectively weakened, so that the carrier's ability to react with water is weakened, and the anti-hydration of catalyst can be sharply enhanced.
