The invention belongs to the field of catalyst synthesis, and in particular relates to a preparation method and application of a viscosity-reducing catalyst for hydrothermal cracking of heavy oil. The specific steps are as follows: weigh ferric chloride and add it to a three-necked beaker; The acid was added to the three-necked flask, magnetic stirring, NaOH was added, the temperature was increased, condensed and refluxed, and the ferric oleate compound and the oleic acid mixture were added to the sodium dialkylbenzene sulfonate, and then dissolved in octyl ether, 1-octadecene or 1-octyl ether. - Program temperature in eicosene, then cool to room temperature, then add ethanol to the solution, and centrifuge to obtain the target product heavy oil hydrothermal cracking viscosity reducing catalyst. The target product of the present invention is cheap and easy to obtain, has low energy consumption, has excellent viscosity reduction effect, and can customize physical properties and nanometer size by selecting correct reaction temperature, reaction solvent or reaction time. |
