2. Fischer-Tropsch synthesis from bio-syngas models over cobalt and cobalt-iron alumina supported catalysts
Abstract : Fischer-Tropsch (FT) synthesis is a process in which synthesis gas (syngas), a mixture of H2 and CO, is converted into long chain hydrocarbons mainly over Co- or Fe-based catalysts. The FT synthesis requires an H2/CO molar ratio (usage ratio) of approximately 2.1 above the catalyst surface. If the inlet syngas H2/CO ratio is less than 2. READ MORE

3. Partial methane oxidation from electronic structure calculations
Abstract : Investigating catalytic reactions with computational methods is a powerful approach to understand fundamental aspects of catalytic reactions and find ways to guide catalytic design. Partial methane oxidation is one example of a reaction with intriguing challenges, where a detailed atomistic approach may help to unravel the bottlenecks of this, as of yet, inefficient reaction.
