A CATALYST FOR CONVERTING ACID-CONTAINING INFERIOR CURDE OIL, AND PROCESSES FOR MAKING AND USING SAME

摘要

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)Na2O•(l-50)MO•(6-58)Al2O3•(40-92)SiO2, 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 200-400m2/g, a pore volume of 0.5-2.0ml/g, an average pore diameter of 8-20nm, and a most probable pore size of 5-15nm. The catalyst provided in the present invention is suitable for the catalytic conversion of crude oil having a total acid number of greater than 0.5mgKOH/g and for the removal of organic acids, carbon residues and metals in crude oil, and thus has very good economic benefits.
