METHOD OF PRODUCING ACTIVATED CLAY FOR TREATING AROMATIC HYDROCARBONS

摘要

THE PRESENT INVENTION PROVIDES AN ACTIVATED CLAY FOR REFINING AROMATIC HYDROCARBONS AS BTX (BENZENE,TOLUENE, XYLENE), ETC., SATISFYING THE REQUIREMENTS OF BOTH EXCELLENT LIFE AND EXCELLENT SIDE -REACTION-PREVENTING PROPERTY. THE ACTIVATED CLAY FOR TREATING AROMATIC HYDROCARBONS IS OBTAINED BY TREATING DIOCTAHEDRAL SMECTITE CLAY MINERALS WITH AN ACID SO AS TO POSSESS A BET SPECIFIC SURFACE AREA OF NOT SMALLER THAN 250 M2/G AND TO CONTAIN IRON IN AN AMOUNT OF NOT SMALLER THAN 2.5BY WEIGHT RECKONED AS AN FE2O3 OXIDE.
