ABSTRACT:
A process is disclosed for the production of high octane alkyl tertiary alkyl ether rich gasoline and gasoline rich in alkylated aromatics. It is disclosed that unreacted C.sub.3 -C.sub.4 hydrocarbon fraction of etherification feedstock plus unreacted alkanol can be separated and employed as alkylating agents in combination with a feedstream containing light aromatics when the alkylation reaction is carried out under conditions of high severity in contact with a high activity shape selective metallosilicate catalyst such as ZSM-5. Under high severity conditions olefin-assisted paraffin conversion also occurs as well as cracking, redistribution and alkylation. Aromatic rich gasoline is a suitable feedstream to the high severity conversion zone to produce a gasoline rich in alkylated aromatics.
