PLANT AND METHOD FOR CATALYTIC AROMATIZATION OF LIQUEFIED HYDROCARBON GASES Russian patent published in 2023 - IPC C07C15/04 C07C15/06 C07C15/08 C07C9/04 C07C4/06 C07C2/76 C07C2/58 C10G35/04 C10G47/00 C10G50/00 C10G63/00 C10G69/00 

FIELD: hydrocarbon production.

SUBSTANCE: systems for catalytic aromatization of liquefied hydrocarbon gases. The system consists of a radiation chamber configured to heat the raw material to the aromatization temperature by combusting the supplied fuel. It also consists of a convection chamber containing reaction pipes with a catalyst, made with the possibility of entering it with heated raw materials leaving the radiation chamber, as well as with the possibility of direct aromatization, also containing a catalyzate exhaust line. At the same time, the convection chamber is configured to operate in an isothermal mode, provided by heating the pipes with the catalyst with flue gases exhausting from the convection chamber. The invention also relates to the use of a plant and a method for the catalytic aromatization of liquefied hydrocarbon gases.

EFFECT: increasing efficiency of processing by improving the thermodynamic conditions for the flow of catalysis.
