Enhancing the properties of Fischer-Tropsch fuel produced from syngas over Co/SiO2 catalyst: Lubricity and Calorific Value

The Effect of Air Fuel Ratio and Temperature on Syngas Composition and Calorific Value Produced from Downdraft Gasifier of Rubber Wood-Coal Mixture

Rubber wood (Ficus elastica) is one the biomass waste that can be used as raw material for a gasification process and has a calorific value of 4,069 cal/gram. Gasification is a process to convert a solid fuel to syngas (CO, CH4, and H2) through a combustion process using limited air between 20% to 40% of air stoichiometry. Depending on the direction of airflow, the gasifiers are classified as u...

The optimally performing Fischer-Tropsch catalyst.

Microkinetics simulations are presented based on DFT-determined elementary reaction steps of the Fischer-Tropsch (FT) reaction. The formation of long-chain hydrocarbons occurs on stepped Ru surfaces with CH as the inserting monomer, whereas planar Ru only produces methane because of slow CO activation. By varying the metal-carbon and metal-oxygen interaction energy, three reactivity regimes are...

Fischer-Tropsch synthesis using bio-syngas and CO2

While Fischer-Tropsch synthesis (FTS) using coal and natural gas in conventional reactors is an almost well-established technology, the production of liquid hydrocarbons from syngas obtained from biomass is in its preliminary stages of commercialization in countries like Germany. With concerns about global warming and ways of disposing of CO2 being searched for, CO2 hydrogenation using FTS to l...

Separation of Fischer-Tropsch Wax from Catalyst by Supercritical Extraction

The Effect of Temperature on Product Distribution over Fe-Cu-K Catalyst in Fischer-Tropsch Synthesis

The iron-based catalyst was prepared by a microemulsion method. The composition of the final nanosized iron catalyst, in terms of the atomic ratio, contains 100Fe/4Cu/2K. The experimental techniques of XRD, BET, TEM, and TPR were used to study the phase, structure, and morphology of the catalyst. Fischer-Tropsch synthesis (FTS) reaction test was performed in a fixed bed reactor under pressure o...
