摘要： 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.

摘要： Disclosed are systems and methods for the production of polyacrylic acid and superabsorbent polymers from ethylene oxidation to form ethylene oxide. Reacting the ethylene oxide with carbon monoxide to form to beta propiolactone (BPL) or polypropiolactone (PPL), or a combination thereof. An outlet configured to provide a carbonylation stream comprising the BPL or PPL, or a combination thereof and using one or more reactors to convert BPL to acrylic acid or to convert at least some of the BPL to PPL, and then to convert PPL to acrylic acid. An outlet configured to provide a PPL stream to a second reactor tm to convert at least some of the PPL to AA or a third reactor to convert at least some of the PPL to AA. The outlet configured to provide an AA stream to a fourth reactor to convert the AA to polyacrylic acid.
