Реферат: [0114] DISCLOSED HEREIN IS A METHOD OF MAKING XYLENE ISOMERS. MORE SPECIFICALLY, THE METHOD INCLUDES CONTACTING A C? AROMATICS-COMPRISING FEED WITH A CATALYST UNDER CONDITIONS SUITABLE FOR CONVERTING THE FEED TO AN INTERMEDIATE PRODUCT STREAM COMPRISING XYLENE ISOMERS, SEPARATING AT LEAST A PORTION OF THE XYLENE ISOMERS FROM THE INTERMEDIATE PRODUCT STREAM, AND RECYCLING TO THE FEED THE XYLENE ISOMERS-LEAN INTERMEDIATE PRODUCT STREAM. ALTERNATIVELY, THE METHOD OF MAKING XYLENE ISOMERS INCLUDES CONTACTING A FEED COMPRISING C? AROMATICS AND LESS THAN ABOUT 30 WT.% BENZENE, BASED ON THE TOTAL WEIGHT OF THE FEED, WITH A NON-SULFIDED, LARGE-PORE ZEOLITE IMPREGNATED WITH A GROUP VIB METAL OXIDE, UNDER CONDITIONS SUITABLE FOR CONVERTING THE FEED TO A PRODUCT STREAM COMPRISING XYLENE ISOMERS. THE DISCLOSED METHOD IS CHARACTERIZED BY UNEXPECTEDLY HIGH RATIOS OF XYLENE ISOMERS TO ETHYLBENZENE, XYLENE ISOMERS TO C? AROMATICS (E.G., METHYLETHYLBENZENE), XYLENE ISOMERS TO C?? AROMATICS, TRIMETHYLBENZENE TO METHYLETHYLBENZENE, BENZENE TO ETHYLBENZENE, IN THE PRODUCT OF THE CONVERSION, AND THE HIGH CONVERSION OF C? AROMATICS AND METHYLETHYLBENZENE.
