摘　　要：生物柴油由于具有可再生、易生物降解、无毒、含硫量低和废气中有害物质排放量小等优点,越来越受到人们的重视。本文在分析固体碱催化剂催化机理的基础上,主要针对以磁性纳米四氧化三铁为载体的核壳结构的负载型催化剂催化转酯化生产生物柴油进行实验。出于节能降耗角度引入了微波辅助技术,探讨耐酸稳定性较好的TiO2作为壳层的纳米催化剂催化酯交换生产生物柴油的可行性。初步实验结果表明,具有磁性纳米核壳结构的纳米TiO2催化剂有希望实现较高的转化率。More and more attention has been paid to bio-diesel for its merits like renewability, high biodegrad- ability, no toxicity, low sulfur content, small emissions of harmful substances, etc. Based on analysis of the catalytic mechanism of solid base catalyst, the paper mainly explores the possibility of producing bio-diesel applying the ester exchange reaction with the support catalyst which has core-shell structure using magnetic nano-Fe3O4 as carrier. Mi- crowave-assisted technology is introduced for saving energy and the paper mainly focuses on the feasibility of ester exchange reaction to produce bio-diesel with acid-resisting TiO2 as a shell layer catalyst. Preliminary experiments show that TiO2 catalyst with the magnetic nano core-shell structure is promising to achieve an ideal bio-diesel conver- slon
