Abstract
A system and method for coproduction in the production of ethylene, including contacting ethane with an oxidative dehydrogenation (ODH) catalyst in presence of oxygen in a first reactor to dehydrogenate ethane to ethylene, and contacting a first-reactor effluent with an ODH catalyst in a second reactor to form ethanol and acetaldehyde.
Claims18
A method, comprising:
- contacting ethane with a first oxidative dehydrogenation (ODH) catalyst in presence of oxygen in a first reactor to produce a first-reactor effluent comprising ethylene, carbon dioxide, and water;
- removing oxygen from the first-reactor effluent upstream of a second reactor to provide a modified first-reactor effluent;
- passing the modified first-reactor effluent from the first reactor to the second reactor;
- and
- contacting the modified first-reactor effluent with a second ODH catalyst in the second reactor to form
- a second-reactor effluent comprising ethylene, ethanol, and acetaldehyde.
