THE PROCESS RELATES TO THE USE OF ANY NAPHTHA-RANGE STREAM CONTAINING A PORTION OF C8+ AROMATICS COMBINED WITH BENZENE, TOLUENE, AND OTHER NON-AROMATICS IN THE SAME BOILING RANGE TO PRODUCE TOLUENE. BY FEEDING THE A8+ CONTAINING STREAM TO A DEALKYLATION/TRANSALKYLATION/CRACKING REACTOR TO INCREASE THE CONCENTRATION OF TOLUENE IN THE STREAM, A MORE SUITABLE FEEDSTOCK FOR THE METHYLATION REACTION CAN BE PRODUCED. THIS STREAM CAN BE OBTAINED FROM A VARIETY OF SOURCES, INCLUDING THE PYGAS STREAM FROM A STEAM CRACKER, “CAT NAPHTHA” FROM A FLUID CATALYTIC CRACKER, OR THE HEAVIER PORTION OF REFORMATE. |
