摘要
生物炭是由生物质在有限供氧条件下,经过高温(通常<700℃)热解制成的一类多孔富炭固态物质,富含C、H、O、N等多种元素。作为一种新型的高效廉价产品,生物炭能够改良土壤、固碳减排、提供清洁能源、修复污染,被广泛应用于工农业、能源、环境等领域。通过概述目前制备生物炭的常用技术及原理,阐述了各技术的优缺点,为利用废弃生物质制备生物炭方法的选择提供了理论依据。
Biochar is a kind of porous carbon-rich solid substances produced by high temperature pyrolysis(usually<700℃)under the condition of limited oxygen supply,which is rich in C,H,O,N and other elements.As a new type of high-efficiency and inexpensive products,biochar can improve soil,increase carbon sequestration potential,provide clean energy,and repair pollution.It is widely used in industry and agriculture,energy,and environment and so on.By summarizing the common technologies and principles of biochar preparation at present,the advantages and disadvantages of each technology were expounded,which provided a theoretical basis for the selection of methods of biochar preparation from waste biomass.
