Abstract

The invention relates to a production method of aromatic hydrocarbons. The method is characterized in that a raw material is in contact with a composite zirconium oxide catalyst under aromatization conditions to generate aromatic hydrocarbon flow containing benzene, toluene and xylene, and the raw material has structural formula (I) shown in the description; in the formula (I), R1 is hydrogen, an optionally substituted C1-20 linear or branched alkyl group, an optionally substituted C2-C20 linear or branched alkenyl group, an optionally substituted C2-20 linear or branched alkynyl group, an optionally substituted C3-C20 cycloalkyl group or an optionally substituted C6-20 aryl group, R2 is an optionally substituted C1-20 linear or branched carboxyl group, a furyl group or a hydroxyalkylfuryl group, and the hydroxyalkylfuryl group has structural formula (II) shown in the description; and in the formula (II), R3 is an optionally substituted C1-20 linear or branched alkyl group, an optionally substituted C2-C20 linear or branched alkenyl group, an optionally substituted C2-20 linear or branched alkynyl group. The method can be used in the field of production of aromatic hydrocarbons from non-fossil resources.

Description

Technical field

[0001] The invention relates to a method for producing aromatic hydrocarbons, in particular to a method for preparing benzene, toluene and xylene light aromatic hydrocarbons. Background technique

[0002] Benzene, toluene, and xylene are important basic organic chemical raw materials for social development. It can derive a variety of product chains by itself or through reproduction. The products are widely used in many fields such as polyester, chemical fiber, rubber, medicine, and fine chemicals. The consumption has reached tens of millions of tons, which has an important impact on the development of the national economy. Benzene is a multi-purpose basic petrochemical raw material that can produce many products derived from it, including ethylbenzene / styrene, cumene / phenol and so on. Paraxylene is mainly used to produce terephthalic acid, through terephthalic acid (PTA) or diethyl terephthalate (DMT) intermediates, used to produce polyester fibers such as polyet...
