Behaviour of iron catalysts in hydrocarbon synthesis from carbon monoxide and steam

摘要: Abstract The function of catalysts in hydrocarbon synthesis from carbon monoxide and steam has been examined by studying changes the oxidation states, surface areas crystallographic properties iron during such synthesis. Evidence is presented that generation hydrocarbons follows an antecedent shift reaction, depends on a dynamic equilibrium between various transient states as well formation surface-active “free” species catalyst. A qualitative set equilibria for catalytic activity outlined.
