Document Type and Number:
WIPO Patent Application WO/2024/088127
Kind Code:
A1
Abstract:
A cracking catalyst for in-situ upgrading of crude oil and a preparation method therefor, and a use thereof. The cracking catalyst for the in-situ upgrading of the crude oil contains naphthalene sulfonate or naphthalene sulfonic acid derivative salts, a naphthalene sulfonic acid or a naphthalene sulfonic acid derivative, a hydroxy naphthoic acid, transition metal organic acid salts, 1,10-phenanthroline, internal olefin sulfonate, a rare earth metal compound, and a solvent. The cracking catalyst for the in-situ upgrading of the crude oil is used for a porous medium containing clay minerals, and an olefin hydrogenation precursor at 350°C or below can be generated by means of the reaction of components such as naphthalene sulfonate, a hydroxy naphthoic acid metal, and internal olefin sulfonic acid rare earth with heavy crude oil.
