The gasification of microalgae in supercritical water was investigated in this work. The product gas contained mainly H2, CO2, CH4, and C2H6. Operation at high temperatures and lower biomass concentrations resulted in the highest carbon gasification efficiency and the lowest total organic carbon levels in the residual water. Due to its content of inorganic nutrients, the residual water was applied as cultivation medium for microalgae. However, algal growth in the untreated residual water was… 
Reutilization of Algal Supercritical Water Gasification Waste for Microalgae Chlorella vulgaris Cultivation
Effluents obtained through a supercritical water gasification (SCWG) process at 400 and 600 °C were mixed with Bristol Medium to cultivate Chlorella vulgaris, indicating the possibility of using a combination of C. vulgaris and SCWG for nutrient recycling processes.
New Application of Supercritical Water Gasification to Palm Oil Mill Effluent: Gasification and Phosphorus Recovery
The simultaneous production of fuel gas and inorganic phosphorus from palm oil mill effluent (POME) in supercritical water was experimentally studied herein. A laboratory-scale continuous reactor was
Hydrothermal liquefaction and gasification of biomass and model compounds: a review
Hydrothermal liquefaction (HTL) and supercritical water gasification (SCWG), two effective thermochemical approaches converting biomass into biofuels, have received increasing attention due to their


SunCHem: an integrated process for the hydrothermal production of methane from microalgae and CO2 mitigation
We describe a potential novel process (SunCHem) for the production of bio-methane via hydrothermal gasification of microalgae, envisioned as a closed-loop system, where the nutrients, water, and CO2
Catalytic and Non-catalytic Supercritical Water Gasification of Microalgae and Glycerol
In this study, we present the gasification of microalgae (Chlorella vulgaris) and glycerol in supercritical water (SCW) using batch (quartz capillaries) and continuous flow reactors. Preliminary
