Hydrocarbon conversion process. [production of gasoline blending stock using etherated gasoline to reduce emissions]
Patent
·
OSTI ID:7359470
A process is given for producing gasoline blending stock which comprises (a) feeding an alcohol and a light hydrocarbon mixture containing at least tertiary olefins, linear olefins and isobutane to an etheration zone, (b) reacting the alcohol with the tertiary olefins in the etheration zone to obtain an ether and unreacted linear olefins and isobutane, (c) separating the ether from the linear olefins and isobutane, (d) feeding water and at least the linear olefins to a hydration zone, (e) reacting water with at least a portion of the linear olefins in the hydration zone to obtain at least a secondary alcohol, (f) separating unreacted olefins and paraffins from the secondary alcohol, (g) feeding at least a portion of the unreacted olefins and paraffins to an alkylation plant for reaction to obtain an alkylate, and (h) blending at least portions of the ether, product alcohol and alkylate to produce a gasoline blending stock.
