Gas to Liquids is a refinery process to convert natural gas (associated oil gas) into high-quality transport fuels and other high-purity petrochemical products.
Sasol and Shell are leaders in GTL today. The Fischer-Tropsch (FT) reactor developed by Sasol is a slurry-type reactor (height: 60 m, diameter: 10 m, weight: about 2500 tones). Shell uses conventional tubular FT multi-channel reactors with a fixed-bed catalyst.
Velocys and Compact GTL work with microchannel reactors. Their technologies are applicable for smaller-scale facilities with stranded oil and gas resources and for offshore.
