Abstract
A system and method for efficiently and sustainably producing propylene and acrylonitrile is disclosed which utilizes biodegradable materials, combustible materials that produce carbon dioxide and/or carbon monoxide. According to one embodiment of the invention, a source of carbon dioxide and/or carbon monoxide is utilized and the carbon dioxide and/or carbon monoxide is electrochemically reduced to ethylene. Dimerization is applied to separate the ethylene to produce 1-butene; which is isomerized to produce 2-butene. The 2-butene is metathesized to produce propylene. The propylene may then be subject to ammoxidation as desired in order to produce acrylonitrile.
Claims19
A method for the production of propylene, comprising the steps of:
- utilizing a source of carbon comprising carbon dioxide and/or carbon monoxide;
- converting through electrolytic reduction or electrochemical reduction said carbon dioxide and/or carbon monoxide to ethylene;
- dimerizing said ethylene by a catalytic process to produce 1-butene;
- using a synthesis process to isomerize said 1-butene to produce 2-butene and to metathesize said 2-butene to produce propylene.
