Abstract
The integrated processes herein provide improved carbon efficiency for processes based on coal or biomass gasification or steam methane reforming. Provided are also ethylene oxide carbonylation products such as beta-propiolactone and succinic anhydride having a bio-based content between 0% and 100%, and methods for producing and analyzing the same.
Claims12
A method comprising:
- a) selecting a target bio-based content for beta-propiolactone;
- b) combining a bio-based ethylene oxide stream and a fossil-based ethylene oxide stream to produce a combined ethylene oxide feed stream;
- and
- c) carbonylating the combined ethylene oxide feed stream using the combined carbon monoxide feed stream in the presence of carbonylation catalyst to produce beta-propiolactone having the target bio-based content selected in step (a).
