Claims38
A process for converting an oxygenate feed to an olefin product comprising:
- contacting the oxygenate feed with a molecular sieve catalyst in a reaction system, and applying electromagnetic energy to the reaction system at conditions effective to convert the oxygenate feed to a product, the product comprising an olefin.
A process for converting an oxygenate feed to an olefin product comprising:
- contacting the oxygenate feed with a SAPO catalyst in a reaction system;
- applying electromagnetic energy to the reaction system at conditions effective to convert the oxygenate feed to an olefin product, wherein the electromagnetic energy is applied at a frequency in the range of from about 10 to about 50,000 MHz and a power in the range of from about 10 watts to about 500 watts.
The process of 21 wherein said conditions comprise a temperature in the range of from about 150° C. to about 650° C., a pressure in the range of from about 10 Pa to about 500 MPa, and a weight hourly space velocity of from about 0.01 hr−1 to about 5000 hr−1.
A process for converting an oxygenate feed to an olefin product comprising:
- contacting the oxygenate feed with a zeolite catalyst in a reaction system;
- applying electromagnetic energy to the reaction system at conditions effective to convert the oxygenate feed to an olefin product, wherein the electromagnetic energy is applied at a frequency in the range of from about 10 to about 50,000 MHz and a power in the range of from about 10 watts to about 500 watts.
The process of 30 wherein said conditions comprise a temperature in the range of from about 150° C. to about 650° C., a pressure in the range of from about 10 Pa to about 500 Mpa, and a weight hourly space velocity of from about 0.01 hr−1 to about 5000 hr−1.
