Document Type and Number:
WIPO Patent Application WO/2023/189238
Kind Code:
A1
Abstract:
A xylene production system comprises: a reaction tank which is filled with a xylene synthesis catalyst and in which a raw material containing methanol and the xylene synthesis catalyst come into contact with each other so as to produce a reaction product that contains aromatic hydrocarbons containing xylene and lower hydrocarbons having not more than 5 carbon atoms; a product line which is connected to the reaction tank and which takes the reaction product from the reaction tank; a gas-liquid separation tank which is connected to the product line and which separates the reaction product that has entered through the product line into the aromatic hydrocarbons in a liquid state and the lower hydrocarbons in a gaseous state; a product line which is connected to the gas-liquid separation tank and which takes the aromatic hydrocarbons in a liquid state from the gas-liquid separation tank; and a recycle line which is connected to the gas-liquid separation tank and which extracts the lower hydrocarbons in a gaseous state from the gas-liquid separation tank and sends the lower hydrocarbons as a part of the raw material to the reaction tank.
