Suppression of Carbon Deposition In the Iron-Catalyzed Production of Lower Olefins from Synthesis Gas

摘要

Utilizing alternative feedstocks to crude oil for the production of olefins is of eminent importance to the chemical industry. Mixtures of carbon monoxide and hydrogen (syngas) produced from natural gas, coal, or biomass can be directly converted into hydrocarbons by the Fischer-Tropsch synthesis (FTS). Cobalt-and iron-based catalysts are applied commercially in FTS processes. While cobalt-based catalysts are preferred for the production of long-chain linear alkanes (transportation fuels), iron-based catalysts are attractive for the production of olefins.
