Process for making olefins |
| abstract |
Disclosed is a method for converting an oxygenate feedstock to an olefin product. In particular, the method incorporates the use of a silicoaluminophosphate molecular sieve catalyst in the manufacture of ethylene and propylene. The method includes contacting an oxygenate-containing feedstock with a silicoaluminophosphate molecular sieve catalyst to form the olefin-containing product in a fluidized bed reactor apparatus including at least a reaction zone and a recirculation zone. Certain ratios of the mass of catalyst in the reaction zone to that of the sum of the mass of catalyst in both the reaction zone and the recirculation zone within the reactor apparatus are specified. |
