Abstract
An additive used in catalytic cracking of hydrocarbons, which is in the form of homogeneous liquid and comprises a composite metal compound, wherein said composite metal compound consists of the oxides, hydroxides, organic acid salts, inorganic acid salts or metal organic complex compounds of at least one of the 1st group metals and at least one of the 2nd group metals, wherein the 1st group metals are selected from the group consisting of the metals of the IIIA, IVA, VA, VIA groups of the Element Period Table, boron, silicon, phosphorous and tellurium; wherein the 2nd group metals are selected from the group consisting of alkali-earth metals, transition metals, and rare earth metals, is disclosed. A process of catalytic cracking of hydrocarbons, utilizing the additive is also disclosed. The additive can passivate metals and promote the oxidation of CO, and is operated easily with production cost decreased.
