Abstract:

The massive consumption of fossil fuels has not only triggered the energy shortage crisis but also caused environmental problems such as global warming. As a third-generation biofuel, microalgae has the natural advantages of wide distribution area, high biomass yield, and strong carbon sequestration capacity, which is considered as one of the renewable resources with the most potential to replace fossil fuels. However, the production of traditional microalgae biofuel has bottlenecks such as low yield, poor heat utilization efficiency and high cost. Microwave pyrolysis is a kind of advanced pyrolysis technology, which has the advantages of high heat transfer efficiency, fast heating rate, and high adaptability of raw materials, providing new ideas for the production of microalgal biomass fuels. The current research status of microwave pyrolysis of microalgae is statistically reviewed by bibliometric methods. A comprehensive summary is made around the products, applications and process parameters of microwave pyrolysis. Finally, the future challenges and development prospects of this technology are proposed. This review aims to provide scientific basis for the innovation and application of microwave pyrolysis of microalgae and promote its further development in the field of renewable energy.

Key words: pyrolysis, microalgae, microwave pyrolysis, renewable energy, biofuel, bioenergy

摘要：

化石燃料的大量消耗不仅引发了能源短缺危机，还造成了全球变暖等环境问题。微藻作为第三代生物质燃料，具有分布面积广、生物质产量高、固碳能力强等优点，被认为是最有潜力替代化石燃料的生物质资源之一。但是，传统微藻生物质燃料的生产存在得率低、热利用效率差、成本高等问题。微波热解是高级热解技术的一种，具有热传递效率高、升温速率高、原料适应性强等优点，为微藻生物质燃料的生产提供新的思路。本文通过文献计量学方法对微藻微波热解的研究现状进行了统计回顾，并围绕微波热解的产物、应用及工艺参数等内容进行了全面总结，最后提出了该工艺面临的未来挑战和发展前景。本文旨在为微藻微波热解工艺的创新与应用提供科学依据，促进其在可再生能源领域的进一步发展。
