Algae Biofuels Hold Promise in China: Supercritical CO2 Extraction Technology

Abstract

In this study, a systematic review of algae biofuels, including their development and production process, is presented. Compared with traditional techniques, supercritical CO2 extraction, known for its high efficiency and environmental sustainability, has been widely applied in extracting plant compounds, oils, and fats, demonstrating its role as a promising alternative in biofuel conversion. The principle and features of supercritical CO2 extraction technology are introduced, and its applications in biofuel production in China are reviewed. The results indicate its broad applicability and substantial scientific value in biofuel production, underscored by its unique extraction mechanisms and operational flexibility and obstacles to its large-scale implementation. Against a future where supercritical CO2 extraction will play a pivotal role in industrial biofuel production due to the technology’s advancement and policy support in China, this review offers comprehensive insights and references to guide future research into and practices of supercritical CO2 extraction and biofuel development.
