Abstract

The invention discloses a gasoline aromatization and isomerization reforming catalyst. The catalyst comprises the following components by weight percent: 0.1-5% of oxide of the metal in IIB group, 0.1-3% of lanthanide metal oxide, 0.1-5% of oxide of the element in VA group, 50-80% of nanosized HZSM-5 and 20%-40% of alumina. The preparation method comprises the following steps: using a nanosized ZSM-5 molecular sieve to prepare the nanosized HZSM-5 carrier, performing hydrothermal treatment, and adopting the isovolumetric impregnation method to load an active component I and an active component II and obtain the target catalyst. The catalyst provided by the invention has good aromatization activity and isomerization activity and a certain desulfurization capacity; and the olefin content (V) of the gasoline product which is prepared by using the catalyst provided by the invention is no more than 30%, the aromatic content (V) is no more than 35%, the benzene content (V) is no more than 1% and the loss of the octane value is no more than 1.

Description

technical field

[0001] The invention relates to a preparation method and application of a gasoline aromatization isomerization catalyst. In particular, it relates to a catalyst preparation method for loading active metal components on nano-scale ZSM-5 molecular sieves. Through the interaction between additives, metal components and molecular sieves, the dispersion of metal active components is improved, and the catalytic performance of the catalyst is improved. . Background technique

[0002] With the improvement of gasoline standards, how to hydro-upgrade to reduce the olefin content in gasoline, remove sulfur compounds, and at the same time make the loss of octane number smaller is the key to gasoline upgrading. The octane number of catalytic cracked gasoline (FCC gasoline) raw materials with low olefin content, high aromatic content and sulfur content less than 200ppm is mainly provided by aromatics and isoparaffins. During the upgrading process, by increasing the selec...
