摘 要:秸秆生物质炭是秸秆在无氧或限制性供氧条件下,经过一定的温度热解得到的固体产物。秸秆生物质炭
由于其灰分含量高、热值偏低,不适合做活性炭、工业用炭甚至机制烧烤炭等,但秸秆炭可以作为肥料还田,被称为
全营养肥,同源性好,更有利于作物的吸收,其不仅可以将原本作物生长过程中吸收的各种大量元素和中微量元素
返回土壤,而且秸秆炭含碳量达 65%以上,具有良好的固碳减排作用。本文结合南京林业大学生物质气化多联产
团队近 20 年来对秸秆生物质炭的研究与产业化的情况,综述了秸秆制备生物质炭技术、设备及产业化进展,讨论
了生物质炭化、干馏、气化联产炭技术的原料适应性、得率、产能和综合经济效益,以期为秸秆制炭产业的发展提供
参考。

Abstract:Straw biochar is a solid product formed by pyrolysis at high temperature under the condition
without oxygen or restricted oxygen supply. Due to its high ash content and low calorific value,in areas
such as activated carbon,industrial carbon application is limited.Returning straw biochar to the soil can
play the role of biochar in carbon sequestration and emission reduction,relieve soil hardening. It can also
help plants absorb metal trace elements to return to the soil,increase soil organic matter content,improve
crop production and quality.The carbon content of straw charcoal is more than 65% to have a good role in
carbon fixation and emission reduction. In this paper, combining with the biomass gasification
polygeneration team of Nanjing Forestry University in the past 20 years on the biochar research and
industrialization.We review the technology,equipment and industrialization progress of biochar production
from straw. Raw material adaptability, yield, capacity and comprehensive economic benefits of straw
biochar production from destructive distillation, carbonization and gasification are discussed to provide
