Fig. 2: H2 production from brown seaweed via ATT and comparisons to previous seaweed gasification studies.

a Major gaseous products generated via SG and ATT reactions performed at 500 °C and 1 atm under a steam atmosphere (temperature program given in the method section). The result is normalized to mmol/(daf)g-seaweed for the direct comparison to the previous seaweed conversion studies. b–d H2 production via CatATT-CC shown in a is compared to previous studies in terms of b—reaction temperature, c—reaction pressure and d—catalyst type.
