Alkanes and alkenes conversion to high octane gasoline

Patent ·
OSTI ID:5463189

This patent describes a process for the conversion of lower alkane and alkene hydrocarbons to high octane gasoline. It comprises: contacting a hydrocarbon feedstock comprising lower alkanes and alkenes with a fluidized bed of acidic, shape selective metallosiliate catalyst in a first conversion zone under high temperature alkane conversion conditions wherein the feedstock contains an amount of lower alkene sufficient to provide an exotherm sufficient to maintain near isothermal reaction conditions whereby an effluent stream is produced comprising higher aliphatic hydrocarbons rich in aromatics; contacting the effluent stream with a fluidized bed of acidic, medium pore metallosilicate catalyst in a second conversion zone at moderate temperature under oligonerization and alkylation conditions whereby a C/sub 5/ + gasoline boiling range product is produced rich in alkylated aromatics.
