Abstract

The invention discloses a method for producing aromatic hydrocarbon by adopting raw materials containing methanol. The raw material containing methanol comprises the methanol and Fischer-Tropsch synthesis naphtha. In the method, the raw materials containing methanol and a catalyst undergo a contact reaction under the condition of producing the aromatic hydrocarbon by using the methanol. By adopting the method disclosed by the invention, the problem that great removed heat is needed to be adopted in the prior art is solved; and the method has the advantages of simple flow and simpleness and convenience for operation. By adopting the method provided by the invention and a good method for processing and utilizing Fischer-Tropsch synthesis naphtha components, aromatic hydrocarbon products are produced or the octane value of the Fischer-Tropsch synthesis naphtha components is increased to gasoline mediated components with a high octane value.

Description

technical field

[0001] The invention relates to a method for preparing aromatic hydrocarbons from raw materials containing methanol. Background technique

[0002] Aromatics are important petrochemical products with high added value. Aromatics in my country mainly come from petroleum resources, and the shortage of petroleum resources in my country determines the shortage of aromatics resources. The direct conversion of resource-rich methanol to produce aromatics is of great value in alleviating the shortage of aromatics, increasing the added value of methanol downstream products, and prolonging the industrial chains of coal chemical and natural gas chemical industries. Using methanol to prepare aromatics is a new way to produce aromatics by non-petroleum route.

[0003] In 1976, Mobil Oil Company carried out the conversion reaction of methanol to hydrocarbons on ZSM-5 molecular sieve catalyst. US4035430 discloses a process in which methanol is converted to gasoline on a ZS...
