What is the difference between iron-molybdenum hydrogenation conversion catalysts and cobalt-molybdenum hydrogenation conversion catalysts?
Iron-molybdenum hydrogenation catalysts are used in the purification of natural gas and coke oven gas to hydrogenate organic sulfur into inorganic sulfur. There are two types of such catalysts: iron-molybdenum and cobalt-molybdenum. Their performance is the same; the main differences lie in price and lifespan. The cobalt-molybdenum type is more expensive but has a longer lifespan.
Iron-molybdenum hydrogenation catalysts are specifically developed for the purification of coke oven gas, where high levels of carbon monoxide are present, by converting organic sulfur into inorganic sulfur; whereas cobalt-molybdenum hydrogenation catalysts are more commonly used for the purification of natural gas, also to convert organic sulfur into inorganic sulfur.
