This invention relates to a petroleum refining method for producing high value-added clean petroleum products and aromatics (Benzene/Toluene/Xylene) together, by which low pollution petroleum products including liquefied petroleum gas or low-sulfur gas oil and aromatics can be efficiently produced together from a fluid catalytic cracked oil fraction.

Process for the preparation of clean fuel and aromatics from hydrocarbon mixtures catalytic cracked on fluid bed

Disclosed herein is a catalyst for xylene isomerization, including: a carrier including a zeolite, having a molar ratio of silica to alumina of 20&#x2dc;100, impregnated with or mixed with a metal salt (I) having an amount of a metal component of 0.05&#x2dc;5.0 wt % relative to a zeolite, and an inorganic binder, in which an amount of the zeolite is 10&#x2dc;90 wt % based on the total amount of the carrier, wherein the carrier is supported with a VIII group metal such that an amount of the VIII group metal is 0.001&#x2dc;3.0 wt % based on a total amount of the catalyst, or is supported with the VII group metal additionally supported with tin, bismuth or lead such that an amount of the tin, bismuth or lead is 0.01-5.0 wt % based on the total amount of the catalyst, and a method of producing the catalyst. The catalyst for xylene isomerization is advantageous in that, when xylene or C8 aromatic compounds are isomerized using the catalyst, the ethylbenzene conversion is increased while the xylene loss is decreased, compared to conventional technologies.
