ИСТИНА

Fischer-Tropsch synthesis (FTS) is an alternative method to produce a variety of chemicals as hydrocarbons and oxygenate from syngas [1]. Both cobalt and iron are used as FTS catalysts, but iron is more preferable because of their low cost, high resistance to poisons and possibility to work under low H2/CO ratio. It is known that iron carbides are active phases in FTS iron-based catalyst [2]. Recently, it was established that activity and selectivity of iron catalyst depend on the composition of the mixture by which catalyst activated [3-5], but the reasons are still unclear. In our research, we investigated the kinetics of carburization FTS iron catalysts in the atmosphere of both carbon monoxide and syngas (CO:H2 = 1:1) by in situ magnetometric method.
