摘要

摘要: 以SO₄^2-/ZrO₂为催化剂对橡胶籽油裂解油进行甲酯化。研究了锆源、焙烧温度及焙烧时间对催化剂活性的影响,分别采用氨气吸附程序升温脱附(NH₃-TPD)和吡啶红外(Py-IR)对固体酸SO₄^2-/ZrO₂的酸性和酸型进行分析。实验结果表明,以ZrOCl₂为锆源,550℃焙烧4 h所得固体酸SO₄^2-/ZrO₂的催化活性最好,性能较稳定。对酯化产物的组成及性能进行了考察,结果表明,酯化产物的各项性能均优于传统工艺制备的生物燃油,且与0^#柴油相近。

Abstract: Esterification of pyrolytic rubber seed oil with SO₄^2-/ZrO₂ soild acid as catalyst was investigated; the effects of zirconium sources, calcination time and temperature on the catalytic performance were considered. The acidic properties of the SO₄^2-/ZrO₂ catalyst were characterized by temperature-programmed desorption of ammonia (NH₃-TPD) and pyridine adsorption infrared spectroscopy (Py-IR). The results indicated that the SO₄^2-/ZrO₂ solid acid prepared by using ZrOCl₂ as zirconium source and calcined at 550℃ for 4 h exhibits high catalytic activity and stability in the esterification of the pyrolytic rubber seed oil. The esterification product obtained as a bio-oil was superior to those prepared via conventional methods; its properties are similar to those of 0^# diesel oil.
