A review of the catalytic gasification of different algae in supercritical water (SCW)

摘要

Among various biomass, algae have unique advantages such as fast growing, high efficient photosynthesis, no competition with crops etc. Supercritical Water Gasification (SCWG) is a potential technology for converting algae biomass into gases (including H_2, CH_4, CO, CO_2), with merits with higher gas yield and lower tar and char etc. A review of the catalytic gasification of different algae in Supercritical Water (SCW) is presented here, summarizing the past research about the gas yield and distribution in production and their corresponding conditions and valuable conclusions for various algae. Finally, based on the literatures above-mentioned, future directions in this field are suggested.
