New breakthrough in coke oven gas hydrogenation catalysts – sulfur-free catalysts!
Thread Content
The iron-molybdenum hydrogenation catalyst used for the deep desulfurization of coke oven gas is primarily employed to convert organic sulfur in the feed gas, with the resulting H2S being absorbed using zinc oxide or iron-manganese desulfurizing agents. However, iron-molybdenum hydrogenation catalysts require sulfidization during use, which is not very convenient; moreover, the sulfiding agents are prone to self-ignition during temporary storage. It causes safety hazards. Sulfur-free catalysts can avoid these problems; after being installed, it can be used by simply raising the temperature and introducing it into the system, just as with zinc oxide desulfurization agents. During operation with a sulfur-free catalyst, the bed temperature rises by about 100°C, and it possesses a strong deoxygenation capability, capable of removing less than 1.5% of the oxygen present. It is used for primary hydrogenation and pre-hydrogenation in Shandong and Hebei respectively. It has been in pre-hydrogenation operation for 5 months so far, and its performance in the future is under observation
I use coke oven gas to produce methanol, and the high oxygen content causes the iron-molybdenum hydrogenation catalyst to overheat frequently. What kind of catalyst do you use?
Which catalyst manufacturer is that? Beijing Sanju or Wuhan Collin?
Looking it up online, it’s W201B, from Wuhan Collin
