Zusammenfassung: | The invention provides a thickened oil hydrothermal cracking catalyst as well as a preparation method and application thereof. The preparation method comprises the following steps: (1) adding ammoniawater into a nickel-containing precursor aqueous solution to adjust the pH value of the nickel-containing precursor aqueous solution; (2) adding solid acid particles into the nickel-containing precursor aqueous solution obtained in the step (1), and stirring to obtain a suspension; centrifuging, washing and drying the suspension to obtain solid powder; (3) calcining the solid powder in a hydrogenatmosphere to obtain solid acid particles of which the surfaces are loaded with nano nickel; and (4) adding oleic acid and the solid acid particles with the surfaces loaded with the nano nickel into the organic solvent to carry out grafting reaction, and then centrifuging, washing and drying after the reaction is finished to obtain catalyst particles with amphiphilic modified surfaces, namely theheavy oil hydrothermal crac |
