• Over 75% of the

world’s known gas reserves are remote and/or stranded

• Could yield 1.5 billion barrels of fuel per year

• Over 4 million barrels per day

• About 15.5 trillion ft3 of stranded gas is flared, vented, or re-injected each year

Synfuels Process using Liquid-Phase Hydrogenation of Acetylene

• Selectively absorbs acetylene• Rejects unwanted gases• Greatly reduces reaction volume • Operates at moderate conditions • No thermal “run-away” gas phase

reaction• Much higher acetylene

concentrations can be used

Summary

• New Synfuels GTL Process dramatically reduces capital cost

• Now majority of stranded gas fields can be utilized

• Unique new technology that blends established industrial practices with patent protected innovation

• Key to the Synfuels process are the innovative steps that isolate and convert intermediates, reducing recycle, compression, and system volumes

• Synfuels liquid-phase hydrogenation is the technology’s cornerstone

• Liquid-phase hydrogenation may be applicable to other hydrogenation processes outside GTL
