Abstract
A process is described for the production of aromatics boiling in the gasoline boiling range from methanol carried out in two stages wherein a heat dissipating diluent is employed in the second stage during contact with a crystalline zeolite catalyst selective for the purpose and the first stage exothermic temperature rise is catalytically restricted.
Claims9
In an exothermic conversion process relied upon for producing gasoline boiling range components from a methanol rich feed which comprises:
- passing preheated methanol feed in contact with a catalyst and under conditions selective for restricting the conversion of methanol to a product comprising dimethyl ether,
- combining a light hydrocarbon gasiform diluent with said product comprising dimethyl ether in an amount which will dissipate exothermic heat released upon subsequent contact with a ZSM-5 type crystalline zeolite conversion catalyst and
- contacting said ether comprising product and said light hydrocarbon diluent with a ZSM-5 type crystalline zeolite under conditions selective for converting said ether to products boiling in the gasoline boiling range.
