1-21. (canceled)
A process for making styrene comprising:
- converting methanol to formaldehyde in one or more first reactors to form a first product stream comprising formaldehyde;
- passing the first product stream to a separation stage for separating formaldehyde from the first product stream;
- and
- reacting toluene and formaldehyde in one or more second reactors over a metal oxide selected from a group consisting of CuO, ZnO—CuO, ZnO—CuO—Al2O3, CuCr2O3, ZnCr2O3, and ZnO—CuO—Cr2O3, to form a second product stream comprising styrene.
