ZEOLITIC ALUMINOSILICATE CATALYST FOR SELECTIVE AROMATICS DISPROPORTIONATION PROCESS

摘要

An improved catalyst and process are disclosed for the selective disproportionation of toluene. The process uses a zeolitic catalyst which is oil-dropped in an aluminum phosphate binder and has an X-ray diffraction pattern showing characteristic intensities at specified Bragg angles. Optionally, th e catalyst is selectively precoked prior to toluene disproportionation. The catalyst and process provide improved selectivity for the production of paraxylene.
