Abstract
Processes for converting methane into an olefin and methanol are provided. The olefin can be ethylene. Certain exemplary processes can involve parallel use of both steam reforming of methane and oxidative dry reforming of methane to prepare syngas. The processes can further involve conversion of syngas to ethylene and to methanol.
Claims14
A process for converting methane into an olefin and methanol, comprising:
- a. contacting methane, carbon dioxide, and oxygen with an oxidative dry reforming catalyst to provide an oxidative dry reforming product mixture comprising carbon monoxide, hydrogen, and water;
- b. contacting methane and water with a steam reforming catalyst to provide a steam reforming product mixture comprising carbon monoxide and hydrogen;
- c. contacting the oxidative dry reforming product mixture with an olefin preparation catalyst to provide an olefin product mixture comprising an olefin and carbon monoxide;
- d. separating carbon monoxide from the olefin product mixture to provide separated carbon monoxide;
- e. combining separated carbon monoxide with at least a portion of the steam reforming product mixture to provide a methanol preparation mixture;
- and
- f. contacting the methanol preparation mixture with a methanol preparation catalyst to provide methanol.
