Biomass to liquid process is a promising alternative to meet the growing demand for liquid fuels in a sustainable way, with this in mind the present study focuses on the fabrication, characterization, and performance of a structured iron catalyst to produce hydrocarbons through Fischer-Tropsch synthesis (FTS). The catalyst was engineered to tackle some of the draw backs conventional supported catalyst, such as low catalyst utilization and poor activity and stability.
The experimental investigation involved the manufacturing of iron-based catalysts using the sponge replication method (powder metallurgy). The resulting structured catalyst reach a one-pass conversion of 85 % with 10 % selectivity to CH4. The performance of the structured iron catalyst was assessed in a fixed-bed reactor under industrially relevant conditions. Notably, this result was reach with syngas ratio typical of gasification on lignocellulosic biomass where the catalyst exhibited superior catalytic activity and selectivity toward desired hydrocarbon products including light olefins and long-chain paraffins, compare to a precipitate catalyst for which conversion was 18%.
The results obtained indicate that the developed structured iron catalyst holds considerable potential for efficient and sustainable hydrocarbon production via Fischer-Tropsch synthesis. The catalyst's excellent performance, coupled with its improved stability and selectivity, offers promising prospects for its application in commercial-scale hydrocarbon synthesis processes.
