Research on Life Cycle Assessment and Optimization Strategies for Green Synthesis Process of Terpene Phenolic Resin
【摘要】 为解决萜烯酚树脂传统合成工艺中存在的资源消耗大、环境污染严重等问题,以苯酚和松节油中的萜烯为原料,基于Aspen Plus模拟软件构建萜烯酚树脂绿色合成流程,系统研究原料选择、反应机理及工艺步骤,并对合成流程开展全生命周期评价,计算全球变暖潜势、酸化潜势和光化学烟雾潜势。结果表明,原料获取和生产阶段是主要贡献环节。据此提出相应的优化策略,即提高反应温度至60℃、压力至0.2 MPa,采用固体酸催化剂并降低使用质量分数至1.5%,以30%生物基萜烯替代松节油,并采用微通道反应器与有机膜分离耦合技术,使废水排放量削减70%,并降低了能源消耗和环境影响。
【Abstract】 In order to solve the problems of large resource consumption and serious environmental pollution existing in the traditional synthesis process of terpene phenolic resin,the green synthesis process of terpene phenolic resin was constructed based on Aspen Plus simulation software with terpenes in phenol and turpentine as raw materials. The selection of raw materials,reaction mechanism and process steps were systematically studied,and the life cycle assessment of the synthesis process was carried out to calculate the global warming potential,acidification potential and photochemical smog potential. The results show that raw material acquisition and production stage are the main contributions. Accordingly,the corresponding optimization strategy was proposed,that is,increasing the reaction temperature to 60 ℃ and pressure to 0. 2 MPa,using solid acid catalyst and reducing the dosage to 1. 5%,replacing turpentine with 30% biogenic terpene,and using the coupling technology of microchannel reactor and organic membrane separation,the wastewater discharge was reduced by 70%,and the energy consumption and environmental impact were reduced.
