Process to make propylene from ethylene and either dimethyl ether, or methanol and dimethyl ether |
| abstract |
The present invention is a process to make propylene comprising: n a) providing a reaction zone containing a catalyst;n nb) introducing a feedstock comprising ethylene, dimethyl ether or methanol and dimethyl ether comprising at least 1000 wppm of dimethyl ether, optionally steam into said reaction zone and into contact with said catalyst;n nc) operating said reaction zone at temperature and pressure conditions to produce an effluent comprising propylene, hydrocarbons, steam, optionally unconverted methanol and/or unconverted dimethyl ether and optionally unconverted ethylene;n nd) sending the effluent of step c) to a fractionation zone to recover propylene optionally methanol and for dimethyl ether and optionally ethylene;n ne) optionally recycling at least a part of methanol and for dimethyl ether and optionally recycling at least a part of ethylene to the reaction zone at step b);n nwherein the catalyst is an acid and the temperature at the inlet of the reaction zone is under 280° C. and advantageously from 50 to 280° C. |
