Abstract
A process combination is disclosed to reduce the aromatics content and increase the oxygen content of a key component of gasoline blends. A naphtha feedstock having a boiling range usually suitable as catalytic-reforming feed is processed by selective isoparaffin synthesis to yield lower-molecular weight hydrocarbons including a high yield of isobutane. The isobutane is processed to yield an ether component by dehydrogenation and etherification. The cracked light naphtha may be upgraded by isomerization. The heavier portion of the cracked naphtha is processed in a reformer. A gasoline component containing oxygen as ether and having a reduced aromatics content and increased volumetric yield relative to reformate of the same octane number is blended from the net products of the above processing steps. The process combination is particularly suited for use in an existing refinery.
