A kind of catalyst for high activity fluid bed

Abstract

The invention discloses a catalyst for a high-activity fluidized bed. The catalyst comprises three layers of active agents and a carrier. The carrier is a zeolite molecular sieve, the first layer of catalyst is a reactive metal oxide catalyst, the second layer of catalyst is a platinum doped aluminum oxide nano catalyst, and the third layer of catalyst is a molybdenum oxide catalyst. The catalyst has proper hole structure distribution and active metal dispersity, and has the advantages of being simple in preparation process, high in activity, incapable of causing saturation of unsaturated olefin and the like.

Description

technical field [0001] The invention belongs to the technical field of gasoline processing, and in particular relates to a high-activity fluid bed catalyst. Background technique [0002] Catalysis is the reaction in which the activation energy of the reactants is changed through the catalyst, the chemical reaction rate of the reactants is changed, and the amount and quality of the catalyst do not change before and after the reaction. In order for a chemical reactant to undergo a chemical reaction, it must change its chemical bond. Changing or breaking a chemical bond requires a certain amount of energy support. The minimum energy threshold required to change a chemical bond is called the activation energy. The activation energy of the chemical reaction is easier to carry out, and the reaction rate is greatly increased. [0003] As early as BC, China had been able to use distiller's yeast (biological enzyme catalyst) to make wine. In the middle of the 18th century, the use ...

Problems solved by technology

In the actual production process, catalysts often have poor efficiency, especially multi-level catalysis, which often has problems such as good results in the early stage and sharp decline in catalytic ability in the later stage.
