F4 Fischer Tropsch Flashcards
What is the main Fischer Tropsch reaction?
The schematic process, from feedstock to fuels (via FT)
Why should we use Fischer-Tropsch?
Some things to remember…
The products distribution (selectivity) can be simplified by a polymerisation process, with CH2 as the monomer. What is the initiation? and the chain growth and termination?
The product selectivity - how does the temperature and pressure affect the length of the hydrocarbons?
How can we use the ideal Anderson-Sculz-Flory (ASF) model to predict the length of the hydrocarbons?
And we can plot the weight fraction against the growth probability (alpha)
The plot of weight fraction against growth probability
Comments about the catalysts of Ni, Fe, Co and Ru (ruthenium)
The process overview of FT from Natural gas
What are the specifics for Low Temperature FT (LTFT) and High Temperature FT (HTFT)?
Low Temperature FT - schematics and product selectivity

Name two High Temperature FT reactors and their specifics (catalyst, and catalyst particle size)
Name two Low Temperature FT reactors and their specifics (catalyst, particle size)
Comparison of Multitubular Fixed Bed Reactor (TFBR) and Slurry Bed Reactor (SBR) - both LTFT reactors
Name if to use HTFT or LTFT, what catalyst, what reactor and what products will be formed when aiming to do Gasoline and Diesel.
What process can be used for FT product upgrading? And what does it entail?
Why BTL????
Differences between GTL, CTL and BTL in cost, feed-to-fuel ratio and change in GHG emissions
Chalenges in BTL applications
Approx. how much does the production of clean syngas stand for in the FT production process?
Typical differences between CTL and BTL
Actions to take regarding challenges in BTL applications?
Integrating BTL plant with paper mills
Possible FT diesel production in the future: Co-production of SNG and diesel
Yeah
