dc.description.abstract | Production of bio-based acetate is commonly hindered by the high costs of the downstream processing. In this
paper, a model is developed to describe a new method that recovers acetate salts using anion exchange resins,
and subsequently desorbs and upgrades them using CO2-expanded alcohol. The model consists of equilibrium
parameters for both the adsorption and desorption step. The calculated parameters are: for the adsorption

maximum experimental concentration of acetic acid obtained in CO2-expanded methanol is 0.427 mol/kg (20 g/
LMeOH) at an operating pressure of 31 bar. The model represents the expected trends for all species, and can be
used to design a multicolumn system for the recovery and upgrading of carboxylates | es_ES |
