Claims
- 1. A process for producing ethylene, propylene and gasoline boiling range fuel product, the process comprising the steps ofi) providing methanol to a refinery comprising a FCC unit and an alkylation unit; ii) producing ethylene, propylene and butene in the FCC unit; iii) isolating ethylene and propylene produced in the FCC unit from butenes produced in the FCC unit; iv) converting the methanol to olefins comprising ethylene, propylene and butenes; v) isolating butenes produced in the step of converting from ethylene and propylene produced in the step of converting; and vi) supplying butene produced in the converting step and butene produced in the FCC unit to the alkylation unit to produce the gasoline boiling range fuel product.
- 2. The process of claim 1, winch further comprises collecting individual streams of the ethylene, propylene, and gasoline boiling range fuel product.
- 3. The process of claim 1, wherein the gasoline boiling range fuel product forms a first gasoline boiling range product stream containing less than 10 ppm sulfur.
- 4. The process of claim 3, which further comprises blending the gasoline boiling range product stream with a second gasoline boiling range product stream which contains at least 10 ppm sulfur to provide a mixed gasoline boiling range product stream having a reduced sulfur content compared to the second gasoline boiling range product stream.
- 5. The process of claim 1 wherein the step of converting the methanol is carried out by a methanol to olefin process.
- 6. The process of claim 1 wherein the step of converting the methanol is carried out in the presence of a shape-selective crystalline silicate catalyst selected from the group consisting of ZSM-5, ZSM-l 1, ZSM-12, ZSM-23, ZSM-35, ZSM-48, MCM-22, SAPO-18, and SAPO-34.
- 7. The process of claim 1 wherein the step of converting the methanol iscarried out in the presence of a shape-selective ZSM-5 crystalline silicate catalyst.
- 8. The process of claim 1 wherein the step of converting the methanol is carried out in the presence of a SAPO-34 crystalline silicate catalyst.
- 9. The process of claim 1 wherein the converting the methanol is carried out in the presence of a SAPO-18 crystalline silicate catalyst.
