This paper reports that a selective toluene disproportionation process based on Mobil's ZSM-5 catalyst, Mstdp, has completed a full 500-day first cycle at Enichem Anic's refinery in Gela, Italy. After regeneration, a second cycle operated for 100 days to confirm the regenerability of the catalyst. For Enichem, the main objective was to evaluate process yields and economics. For Mobil, the main objective was to demonstrate commercial catalyst selectivation (the establishment of high selectivity through a pretreatment step), cycle length, and regenerability.
