Patent ID: 7780847

Claim:
A process for reducing the sulfur content of a catalytically cracked gasoline stream containing alkylated thiophenic, benzothiophene, alkylated benzothiophenic and other sulfur compounds comprising the steps of: providing a catalytically cracked gasoline stream having a boiling point range of about 0° C. to 300° C.; contacting all the catalytically cracked gasoline stream with an adsorbent to adsorptively remove substantially all the alkylated thiophenic, benzothiophene and alkylated benzothiophenic sulfur compounds from the stream to produce an adsorptively treated stream containing the other sulfur compounds, the catalytically cracked gasoline stream having an initial boiling point range including light and heavy fractions; hydrodesulphurizing the adsorptively treated stream with a solid catalyst to separate substantially all of the other sulfur compounds from the adsorptively treated stream; and stripping the other sulfur compounds from the adsorptively treated stream to produce a product gasoline stream, whereby the product gasoline stream has a reduced sulfur content and a substantially similar octane rating as the catalytically cracked gasoline stream.
