Abstract A transition metal oxide catalyst of copper oxide nanoparticles was synthesized by a conventional non-hydrothermal method. It was studied as a catalyst in thermocatalytic upgrading and viscosity reduction of heavy oil in the laboratory. The experimental results showed that the viscosity of heavy oil may be reduced by 85.75% with 0.2 wt% catalyst at 350 °C for 40 min. With determinations of analyzation, it was found that under the thermocatalytic action of copper oxide nanoparticles, the presence of hydrogen-donor in the reaction could further improve the chemical constitution of resin and asphaltene in heavy oil.

氧化铜纳米颗粒对重油的热催化改质降粘

摘要 采用常规非水热法合成了氧化铜纳米颗粒过渡金属氧化物催化剂。实验室研究了作为重油热催化提质降粘的催化剂。实验结果表明，在 350 ℃ 40 min 条件下，加入 0.2 wt% 的催化剂可使稠油的粘度降低 85.75%。通过分析测定发现，在氧化铜纳米粒子的热催化作用下，反应中供氢体的存在可以进一步改善稠油中树脂和沥青质的化学组成。
