Abstract

The invention relates to a naphtha catalytic reforming method which includes the steps as follows: the naphtha is pumped into the reactor of a catalytic reforming device; gas-liquid separation is carried out on the reformed product for separating gas components, the light component of C8- as well as the heavy component of C9+; then a light aromatics reaction is carried out on the heavy component of C9+ under the existence of a light aromatics catalyst; the hydrogen used by the light aromatics reaction is from the circulated hydrogen generated from a reforming device; then gas-liquid separation is carried out on the product after the light aromatics reaction; the liquid returns to the liquid product distilling system of the reforming device. The method can fully utilize the heavy component of C9+ and convert the heavy component into light aromatic hydrocarbon, improve the aromatic hydrocarbon yield or the yield of the reformed gasoline during the whole process and improve the character of the gasoline.

Description

technical field

[0001] The invention is a method for catalytic reforming of naphtha, specifically, a method for making full use of C in the catalytic reforming product of naphtha. 9 + A method of lightening a heavy product. Background technique

[0002] Catalytic reforming is one of the processing technologies of petroleum products. Its process is to convert naphtha into high-octane gasoline or reformed products rich in aromatics through catalytic reaction, and at the same time produce rich and cheap hydrogen. In the catalytic reforming process, naphtha rich in paraffins and naphthenes is in contact with a reforming catalyst containing platinum under certain conditions, and the following reactions mainly occur: dehydrogenation of naphthenes into aromatics, dehydrogenation of paraffins into aromatics, isomerization of paraffins and naphthenes, and hydrocracking of paraffins.

[0003] The liquid product of catalytic reforming of naphtha is a hydrocarbon mixture rich in arom...
