A, product features
LYB-99 series co low temperature shift catalyst, cobalt molybdenum as main active component, the gamma -Al2O3 ball carrier, and adding active additives special, is suitable for the pressure of <3.0MPa, in small nitrogenous fertilizer planttransformation process in series in the low, low, low low temperature shift process,the process is also suitable for methanol synthesis converter and city gastransformation. The utility model has the advantages of:
1 good low temperature activity. Transform furnace entrance can obtain ideal in 180~200 ℃ transformation rate.
2 transform high activity and activity stability. Due to the addition of dispersantspecial, the active component is highly dispersed cobalt molybdenum, active center to increase, so it has high transfer activity and excellent stability at low temperature.
3 strength and strength stability. After curing, not easy powder, peeling, intensity can be maintained for more than 5 years.
4 easy to sulfide.
5 operating temperature range. The normal operating temperature of 180~400 ℃,200~300 ℃ temperature optimum activity.
6 good selectivity, no methanation reaction.
7 good water resistance, catalyst after the blisters are not broken, not powder.
