Abstract:
A process for the disproportionation of a toluene containing feedstock comprising:(a) providing a reaction zone containing a mordenite-type toluene disproportionation catalyst; (b) supplying a toluene feedstock having a toluene content within the range of 80-90 wt. % toluene and a C6-C8 non-aromatic content within the range of 10-20 wt. % to said reaction zone; (c) supplying hydrogen to said reaction zone; (d) operating said reaction zone under temperature and pressure conditions effective to cause the disproportionation of said toluene to benzene and xylene and concomitantly cracking of said non-aromatic hydrocarbons to convert the predominant portion of said non-aromatic hydrocarbon content to lower molecular weight hydrocarbons to produce a lower boiling fraction in the LPG boiling range; and (e) recovering a product stream from said reaction zone containing toluene, benzene and xylene, together with C2-C4 hydrocarbons.
