Biofuels have become an attractive energy source because of the growing energy demand and environmental issues faced by fossil fuel consumption. Algal biomass, particularly microalgae, has excellent potential as feedstock to be converted to bio-oil, biochar, and combustible syngas via thermochemical conversion processes. Third-generation biofuels from microalgal feedstock are the promising option, followed by the first-generation and second-generation biofuels. This paper provides a review of the applications of thermochemical conversion techniques for biofuel production from algal biomass, comprising pyrolysis, gasification, liquefaction, and combustion processes. The progress in the thermochemical conversion of algal biomass is summarized, emphasizing the application of pyrolysis for its benefits over other processes. The review also encompasses the challenges and perspectives associated with the valorization of microalgae to biofuels ascertaining the potential opportunities and possibilities of extending the research into this area.
由于能源需求的增长和化石燃料消耗所带来的环境问题，生物燃料已成为一种极具吸引力的能源。藻类生物质，特别是微藻，具有作为原料转化为生物油、生物炭和可燃合成气的巨大潜力，可通过热化学转化工艺实现。微藻原料的第三代生物燃料是有前途的选择，其次是第一代和第二代生物燃料。本文综述了热化学转化技术在藻类生物质生物燃料生产中的应用，包括热解、气化、液化和燃烧过程。总结了藻类生物质热化学转化的进展，强调了热解在其他过程中的优势。该综述还涵盖了将微藻增值为生物燃料所面临的挑战和前景，确定了将该研究扩展到这一领域的潜在机会和可能性。
