Abstract

Abstract lcohols, especially methanol, are converted into light olefins rich in ethylene and C 5 + hydrocarbon products. After separation of ethylene, propylene and butenes may be converted into olefinic gasoline and olefinic distillate. The distillate product may be treated with hydrogen to produce a high quality diesel and/or jet fuel.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 75 words
A process for converting reactants comprising lower alcohols and related oxygenates into C 5 + and lower boiling hydrocarbon compounds including light olefins and gasoline boiling components, which comprises passing a suspension of vaporized reactant material and fluid catalyst particles comprising a crystalline zeolite upwardly through a dispersed catalyst contact and reaction zone at an elevated temperature and pressure to achieve at least 40% but less than 90% conversion of the alcohol in the feed.
Claim 2
Dependent Claim 75 words
A process for converting reactants comprising lower alcohols and related oxygenates into C 5 + and lower boiling hydrocarbon compounds including light olefins and gasoline boiling components, which comprises passing a suspension of vaporized reactant material and fluid catalyst particles comprising a crystalline zeolite upwardly through a dispersed catalyst contact and reaction zone at an elevated temperature and pressure to achieve at least 40% but less than 90% conversion of the alcohol in the feed.
Claim 3
Dependent Claim 15 words
A process in accordance with Claim 1, wherein the temperature is from 260° to 510°C.
Claim 4
Dependent Claim 14 words
A process in accordance with Claim 1, wherein the temperature is from 315_to 370°C.
Claim 5
Dependent Claim 21 words
A process in accordance with any one of Claims 1 to 3, wherein the pressure is from 170 to 515 kPa.
Claim 6
Dependent Claim 44 words
A process in accordance with any one of Claims 1 to 4, wherein the fluid catalyst particles are continuously cooled by withdrawing a portion of the particles from the reaction zone, cooling the particles and returning the cooled catalyst particles to the reaction zone.
Claim 7
Dependent Claim 28 words
A process in accordance with Claim 5, wherein the catalyst is cooled to a temperature of 28 to 83°C below the reaction zone temperature but not below 260°C.
Claim 8
Dependent Claim 18 words
A process in accordance with any one of Claims 1 to 6, wherein the crystalline zeolite is ZSM-5.
Claim 9
Dependent Claim 19 words
A process in accordance with Claim 7, wherein the ZSM-5 has a crystal size of 0.5 to 4 microns.
Claim 10
Dependent Claim 18 words
A process in accordance with any one of Claims 1 to 6, wherein the crystalline zeolite is ZSM-34.
Claim 11
Dependent Claim 20 words
A process in accordance with any one of Claims 1 to 9, wherein the zeolite has been pretreated by steaming.
