Oil-Soluble Exogenous Catalysts and Reservoir Minerals Synergistically Catalyze the Aquathermolysis of Heavy Oil

Oil is the “blood” and economic lifeblood of modern industry, but traditional light crude oil has been over-consumed, it difficult to meet human demand for energy, so exploitation heavy particularly important. In this paper, an oil-soluble catalyst was synthesized catalyze pyrolysis reaction in collaboration with reservoir minerals, as achieve efficient viscosity reduction reduce production costs. The experimental results showed that Zn(II)O + K had best synergistic effect after aquathermolysis No. 1 sample under conditions 180 °C, 4 h, 30% water, 0.2% catalyst, respectively, rate 61.74%. Under catalysis isopropanol system, increased 91.22%. A series characterizations such freezing point, thermogravimetric analysis, DSC component gas chromatography, wax crystal morphology GC-MS analysis aqueous organic matter were carried out on by different systems, could be verified reduced. Finally, through study mechanism model compound, combined phase can clearly found depolymerization between macromolecules, breaking heteroatom chains, hydrogenation, ring opening, other effects mainly occur during reaction, thereby weakening van der Waals force hydrogen bond recombinant interval, inhibiting formation grid structure effectively reducing oil.
