In situ preparation of well-dispersed CuO nanocatalysts in heavy oil for catalytic aquathermolysis

Abstract We developed an in situ synthesis strategy for preparing well-dispersed CuO nanoparticles as aquathermolysis catalyst for viscosity reduction in Shengli heavy oil (China). A Cu(OH)2-contained microemulsion was employed as a carrier to disperse the precursor Cu(OH)2 to the heavy oil phase. U...
