Conversion of Microalgae under Hydrothermal Conditions

Abstract

A new and green technology for converting microalgae to high value-added chemicals with solid metal oxides catalysts under hydrothermal conditions was proposed. The results indicated that ZrO2, among other test catalysts, can prominently boost the production of acetic acid and a highest yield of 24% was achieved at 300 °C for 2 h with a filling rate of 50%. The metal oxides catalyst provided a promising solution to obtain acetic acid from microalgae conversion.
