Disclosed is an alkane dehydrogenation circulating device, including a reaction device and a regeneration device. The reaction device includes a reactor and a reaction disengager, the reaction disengager is communicated with the reactor, and the reactor is provided with a catalyst distributor through which a catalyst is sprayed into the reactor along a direction from the peripheral wall of the reactor to the central axis of the reactor; the regeneration device includes a regenerator accommodating the catalyst and a regeneration disengager located above the regenerator.

Alkane catalytic dehydrogenation reaction device and catalyst regeneration device

A method for catalytic cracking of naphtha is provided. Naphtha is catalytically cracked under the action of a catalyst. The catalyst includes aluminosilicate, alkali metal oxide, alkaline earth metal oxide, TiO, iron oxide, vanadium oxide and nickel oxide. On the other hand, a rapid separation component is arranged in a disengager of a catalytic cracking reaction device, so that a transport disengaging height is greatly reduced without changing a gas flow and a diameter of the disengager. In addition, the separation efficiency of oil gas and the catalyst is improved.

Naphtha catalytic cracking catalyst, catalytic cracking method and reaction device

A reaction-regeneration device for catalytic dehydrogenation or/and catalytic cracking of alkanes comprises a reaction device and a regeneration device. The reaction device comprises a reactor and a disengager, and the disengager is located at an upper part of the reactor. The reactor comprises a tapering section, and diameters of cross sections of the tapering section gradually decrease from bottom to top. Secondary conversion of alkenes caused by back-mixing is reduced, and thus the yield and selectivity to alkenes are increased.
