林业“三剩物”的开发利用现状和前景概述

Summary of Current Situation and Prospect of Utilization and Exploitation of the Remainders from Forestry Industry

目前国内"三剩物"(采伐剩余物、造材剩余物和加工剩余物)以作为人造板和制浆造纸的原料、制备化学品以及作为直接和间接燃料的形式被利用.国际上林业剩余物能源的研究开发主要集中于气化(使有机物转化成可燃气体)、液化(利用生物发酵或酸水解技术制取乙醇和通过热解等技术转化成液化油)和固化(林业剩余物能源固化成型技术).未来林业"三剩物"的开发利用将集中在:作为木材的替代资源的开发利用;以木材"三剩物"和次小薪材为原料生产加工综合利用产品;林业"三剩物"高品质生物质能源产品的开发.

At present,three kinds of remainder are domestically utilized as materials for paper pulping and wood-based panels＇ making,cosmetics,direct and indirect fuels.While,the exploitation of forestry remainders is internationally concentrated on the vaporization,liquidization and solidification.In the future,the utilization of the remainders will be mainly on timer substitutes and comprehensively used products,and the exploitation of high-quality bio-energetic products will also be emphasized.
