将热裂解液化得到的生物油作为清洁化工原料用于制备酚醛树脂胶黏剂是林木生物质高效利用的重要方式。本文介绍了林木生物质热裂解液化制取生物油及生物油制备胶黏剂的技术概况,对比分析了生物油的利用方式,以河北地区年 4000t 处理量规模为例,对林木生物质热裂解液化生产线设备组成及投资规模、生物油生产成本和生物油替代苯酚制备酚醛树脂胶黏剂的经济效益等进行了探讨。分析表明,河北地区年 4000t 处理量的林木生物质热裂解液化项目投资约为 250 万元,生物油的实际生产成本约为 1200 元/t,将生物油全部用于制备酚醛树脂胶黏剂的直接经济效益至少可达 330 万元/a。林木生物质热裂解液化制备胶黏剂项目技术经济效益显著,具有良好的发展和应用前景。
An important and efficient way for forest biomass utilization is to prepare the phenol-formaldehyde resin adhesive by taking bio-oil from its' pyrolysis-liquefied as a clean chemical raw-materials.The technical progress in pyrolysis liquefaction of forest biomass and preparation of environmental adhesive with bio-oil was introduced.The approaches of bio-oil usage were comparatively analyzed.By taking the process capacity of 4000t in Hebei Province as example,equipment composition and investment scale of biomass pyrolysis liquefaction production line,the cost of bio-oil,and economic benefits of phenol-formaldehyde resin with bio-oil instead of phenol were analyzed and discussed.Analysis shows that the investment of forest biomass pyrolysis liquefaction project with the capacity of 4000t in Hebei Province is about 2.5 million RMB Yuan,and the actual production cost of bio-oil is about 1200 RMB Yuan per ton,the direct economic benefit when all bio-oil are used to prepare the phenol-formaldehyde resin adhesive is up to 3.3 million RMB Yuan per year.The project of forest biomass pyrolysis liquefaction for the preparation of adhesive is a kind of advanced and mature technology that has significant economic benefits and with good prospects for the development and applications.
