High-yield hydrogen production by supercritical water gasification of various feedstocks: Alcohols, glucose, glycerol and long-chain alkanes

- Continuous supercritical water gasification for high-yield H2 production.
- H2 yields from various feedstocks were similar to theoretical equilibrium values.
- Oxygenated hydrocarbons were easier to gasify when compared with long-chain alkanes.
- Branched hydrocarbon was more resistant to gasification when compared with linear alkane.
