Exxonmobil’s MTDP-3 process is the state-of-the-art process for toluene disproportionation to benzene and mixed xylenes. The technology, based on a proprietary zeolite catalyst, offers high product yields at high toluene conversion. MTDP-3 is designed to process toluene and limited amounts of C9 aromatics, and can allow for inexpensive debottlenecking of existing toluene disproportionation (TDP) facilities. MTDP-3 is ideal for toluene upgrade to more valuable chemicals without investing in paraxylene separation facilities. Benzene product exceeds 99.9% purity, thus additional extraction capacity is not required. MTDP-3 has been operated commercially at multiple licensees’ sites for more than 20 years.
Key Benefits:
Lower Costs
Low catalyst costs
Low H2 consumption
Low operating costs
High Product Yields
High benzene and mixed xylene yields
Superior xylene/benzene ratio
High Product Purity
Benzene product with >99.9% purity
Advantages:
Very high toluene conversion per pass
High benzene product and mixed xylenes product yields
High weight hourly space velocity
Superior xylenes/benzene ratio
Benzene product with greater than 99.9% purity
Very low H2 consumption
Low catalyst cost
Low operating cost
Long catalyst cycles with stable product yields across the cycle
