Monodispersed iron-based catalyst for Fischer-Tropsch process, preparation method therefor and use thereof

摘要

Disclose are a monodispersed iron-based catalyst for the Fischer-Tropsch process, a preparation method therefor and the use thereof. The catalyst comprises a carrier, i.e. silicon dioxide and an active component, i.e. iron. The carrier, i.e. silicon dioxide has a mesoporous spherical particle structure, and the carrier, i.e. silicon dioxide covers the active component, i.e. iron. The active component, i.e. iron is of a nanoparticle shape and is distributed uniformly. The particle size of the carrier, i.e. silicon dioxide particle is 140 - 160 nm. In the preparation method therefor, the pressure of CO
