The present disclosure provides catalysts comprising zinc and one or more ligands that improve the hydration of carbon dioxide at a zinc metal center, including but not limited to ethylenediaminetetraacetic acid and its derivatives. In certain embodiments, one or more of the ligands on the zinc is water that is replaced with carbon dioxide. In certain embodiments, the zinc catalyst coordinates an appropriate carbon dioxide adsorption solvent to reduce the activation energy for carbon dioxide hydration. Methods and apparatuses that are designed to efficiently utilize sorbents with improved sorption and desorption characteristics, such as those that include an inorganic catalyst or modified carbonic anhydrase, are also disclosed.

A method for producing dicarboxylic acid. The method includes: subjecting a raw material system including a cyclic olefin and a lower monocarboxylic acid to an addition reaction in the presence of an addition reaction catalyst to generate an intermediate product system including cyclic carboxylic acid ester; and subjecting the intermediate product system including cyclic carboxylic acid ester to a ring-opening and oxidation reaction in the presence of an oxidant and an oxidation catalyst to generate a corresponding dicarboxylic acid product. The addition reaction in the dicarboxylic acid synthesis route achieves a high single-pass conversion rate, and the selectivity of the corresponding cyclic carboxylic acid ester is high. The addition-oxidation synthesis route achieves faster reaction rates for both the addition reaction and oxidation reaction, and high yield of corresponding dicarboxylic acid product. The addition-oxidation based synthesis route is suitable for continuous, stable and large-scale production of corresponding dicarboxylic acid product.
