Abstract:
A mol. sieve catalyst useful in the conversion of hydrocarbons containing niobium is disclosed, along with a process for the disproportionation of toluene to benzene and xylene using such catalyst.

Please note:  Titles for patent records in CAplus are routinely enhanced to better describe the claimed invention. In this example, The title of the U.S. granted patent is Toluene disproportionation using Nb/mordenite catalyst. CAS enhanced the title to read Toluene disproportionation using niobium mordenite molecular sieve catalysts.
