Claims31
A process for making styrene comprising:
- reacting toluene with a C1 source over a catalyst in one or more reactors to form a product stream comprising styrene;
- wherein the catalyst time on stream prior to regeneration is less than 1 hour.
A process for making styrene comprising:
- converting at least a portion of a C1 source to formaldehyde in one or more fluidized bed reactors containing a catalyst;
- reacting toluene with the formaldehyde in the one or more reactors to form a product stream comprising styrene and ethylbenzene;
- withdrawing the product stream and spent catalyst from the one or more fluidized reactors;
- regenerating the spent catalyst in a catalyst regeneration zone to produce regenerated catalyst;
- and
- recycling the regenerated catalyst to the one or more reactors.
