Document Type and Number:
WIPO Patent Application WO/2023/248499
Kind Code:
A1
Abstract:
[Problem] To provide a method for producing a monocyclic aromatic hydrocarbon, such as benzene and xylene, which are effective as basic raw materials, by using a naphtha raw material including a renewable naphtha. [Solution] This method for producing a monocyclic aromatic hydrocarbon is a method for producing at least one monocyclic aromatic hydrocarbon among benzene and xylene by using a naphtha raw material including a renewable naphtha, and comprises: a step (A-1) for producing and separating toluene by thermally decomposing the naphtha raw material in the presence of water vapor; and a step (A-2) for producing and separating at least one monocyclic aromatic hydrocarbon among benzene and xylene through a disproportionation reaction or transalkylation reaction of toluene.
