Abstract
The present invention relates to a catalyst for converting inferior acid-containing crude oil. Based on the total amount of the catalyst, said catalyst comprises from 1 to 50 wt % of a mesopore material, from 1 to 60 wt % of molecular sieves and from 5 to 98 wt % of thermotolerant inorganic oxides and from 0 to 70 wt % of clays. Said mesopore material is an amorphous material containing alkaline earth oxide, silica and alumina, and has an anhydrous chemical formula of (0-0.3)NaO.(1-50)MO.(6-58)AlO.(40-92)SiO, based on the weight percent of the oxides, wherein M is one or more selected from Mg, Ca and Ba. Said mesopore material has a specific surface area of 200-400 m/g, a pore volume of 0.5-2.0 ml/g, an average pore diameter of 8-20 nm, and a most probable pore size of 5-15 nm. The catalyst provided in the present invention is suitable for the catalytic conversion of crude oil having a total acid number of greater than 0.5 mgKOH/g and for the removal of organic acids, carbon residues and metals in crude oil, and thus has very good economic benefits.
