Project Description
This MSc dissertation focused on the development of core-shell cobalt-based catalysts for the production of liquid hydrocarbons via the Fischer-Tropsch (FT) reaction, followed by the upgrading of the products into usable fuels in a single-step process.
Main Outcomes
·Catalytic testing revealed an overall lower activity for the core-shell samples; however, they exhibited a stronger affinity for hydrocracking and hydroisomerization, enabling the breakdown of longer-chain hydrocarbons, such as waxes, and enhancing selectivity towards branched isomers.
·When a zeolite shell was added over a metal oxide core, hydrocarbon selectivity shifted towards the gasoline range, while the metal oxide core itself showed a high affinity for the C12-C20 range.
·The addition of a zeolite shell over a zeolite core reduced selectivity for the gasoline range and increased diesel and jet fuel production, whereas the zeolite core alone showed a strong selectivity for the gasoline range.
