摘要
以水热法合成纳米催化剂,探讨其合成条件对纳米催化剂尺寸的影响并研究其对稠油的降黏效果。先通过水热法合成5种纳米催化剂,比较其水热稳定性。以水热稳定性最好的纳米Fe_(2)O_(3)为核心,通过激光散射实验,筛选出制备纳米Fe_(2)O_(3)的最佳反应条件,即用0.05 mol/L 1-丁基-3-甲基咪唑氯化物([Bmim]Cl)活性剂辅助三氯化铁和乙酸钾(摩尔比为1∶3)在110℃下反应8 h制备纳米Fe_(2)O_(3)。最后,使用纳米Fe_(2)O_(3)对稠油进行降黏,稠油的降黏率为45.83%。实验结果有利于纳米催化剂的改造以及提高稠油采收率。
The nano-catalysts were synthesized by a hydrothermal method to investigate the effect of the synthesis conditions on the nano-catalyst size and to study its viscosity reduction effect on heavy oil.First,five nano-catalysts were synthesized by hydrothermal method to compare their hydrothermal stability.The best reaction conditions for the preparation of nano-Fe_(2)O_(3) were screened by laser scattering experiments with the best hydrothermal stability of nano-Fe_(2)O_(3) as the core.Then,nano-Fe_(2)O_(3) was prepared by reacting ferric chloride and potassium acetate(molar ratio of 1∶3)assisted with 0.05 mol/L 1-butyl-3-methylimidazolium chloride activator([Bmim]Cl)at 110℃for 8 h.Finally,the catalytic upgrading of heavy oil was performed with nano Fe_(2)O_(3).The viscosity reduction of heavy oil was 45.83%.The experimental results were favorable for the modification of nano-catalysts and the enhancement of thick oil recovery.
