摘要

在全球能源转型和碳减排需求的推动下，热解技术因能够高效地将生物质转化为高价值的能源和化学品而成为研究热点。然而，传统的加热技术存在着传热效率低、能量损失大、产品选择性差等问题。有希望的策略包括整合先进的加热技术和选择合适的催化剂。本文首先介绍了传统加热、微波加热和电磁感应加热的加热机理。随后，对三种加热反应器的特性进行了比较，并进一步阐明了它们的传热机理。进一步讨论了每种加热方式对产物分布和产率的影响，突出了各自在生物质热解中的优势。此外，系统地评价了催化剂的作用，特别是在微波和电磁感应加热下的作用。微波加热（0.3-300 GHz）和电磁感应加热（10 kHz-10 MHz）利用电磁波直接加热原料内的热点。此外，电磁感应加热可降低能耗40%以上，木质素感应加热得到的酚类可达100%。本文旨在为节能加热策略和催化热解提供新的见解，为下一代生物质热解技术的发展提供指导。

Rethinking energy delivery in biomass pyrolysis: Comparative insights into conventional, microwave, and induction heating

Driven by the demands of global energy transition and carbon emission reduction, pyrolysis technology has become a research hotspot due to its ability to efficiently convert biomass into high-value energy and chemicals. However, conventional heating technologies are limited by low heat transfer efficiency, high energy loss, and poor product selectivity. Promising strategies include integrating advanced heating techniques and selecting appropriate catalysts. This review first introduces the heating mechanisms of conventional heating, microwave heating, and electromagnetic induction heating. Subsequently, the characteristics of the three heating reactors are compared, and their heat transfer mechanisms are further elucidated. The impact of each heating method on product distribution and yield is further discussed, highlighting their respective advantages in biomass pyrolysis. In addition, the role of catalysts, especially under microwave and electromagnetic induction heating, is systematically evaluated. In this review, microwave heating (0.3–300 GHz) and electromagnetic induction heating (10 kHz-10 MHz) utilize electromagnetic waves to directly heat hotspots within feedstocks. Moreover, electromagnetic induction heating can reduce energy consumption by more than 40 %, and the phenols obtained from induction heating of lignin can reach up to 100 %. This review aims to provide new insights into energy-efficient heating strategies and catalysis-assisted pyrolysis, offering guidance for the development of next-generation biomass pyrolysis technologies.

期刊介绍： Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials. The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy. Key areas covered by the journal: • Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation. • Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal. • Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes • Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation • Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
