Harandi, M N

This patent describes a continuous process for conversion of C/sub 2/-C/sub 4/ alkanes to aromatic rich hydrocarbons boiling in the gasoline range comprising: maintaining a dual vertical column reactor comprising a lower transport riser reaction zone and an upper turbulent fluidized bed reaction zone, both zones containing fluidized catalyst comprising acid medium pore metallosilicate zeolite; contacting a feedstock comprising at least one C/sub 2/-C/sub 4/ alkane with fluidized catalyst in the lower transport zone under high temperature dehydrogenation conditions to dehydrogenate the feedstock and substantially prevent cracking reactions to obtain an intermediate product comprising dehydrogenated hydrocarbons and aromatics; and contacting the intermediate hydrocarbon product with fluidized catalyst in the upper turbulent zone under lower temperature oligomerization conditions to obtain a final product comprising C/sub 5/+ gasoline boiling range hydrocarbons.
