This review lays great emphasis on production and characteristics of biochar through gasification. Specifically, the physicochemical properties and yield of biochar through the diverse gasification conditions associated with various types of biomass were extensively evaluated. In addition, potential application scenarios of biochar through gasification were explored and their environmental implications were discussed. To qualitatively evaluate biochar sustainability through the gasification process, all gasification products (i.e., syngas and biochar) were evaluated via life cycle assessment (LCA). A concept of balancing syngas and biochar production for an economically and environmentally feasible gasification system was proposed and relevant challenges and solutions were suggested in this review.
本综述重点介绍了通过气化生产生物炭的情况和特点。具体而言，广泛评估了不同类型生物质在不同气化条件下的生物炭理化性质和产率。此外，还探讨了气化生物炭的潜在应用场景及其环境影响。为了通过气化过程定性评估生物炭的可持续性，通过生命周期评估（LCA）对所有气化产品（即合成气和生物炭）进行了评估。本综述提出了一个概念，即平衡合成气和生物炭的生产，以实现经济和环境可行的气化系统，并提出了相关的挑战和解决方案。
