| dc.description.abstract | The implementation of biorefineries for the production of chemicals as well as materials and energy products is the key to ensure a sustainable future for the chemical and allied industries. LSRE has been working with lignin based bio-refining for near two decades with pioneering work on the subject. A Research & Development Program on the production of phenolic aldehydes, in particular vanillin, from Kraft lignin has been developed for many years. In this work, the strategy is to combine reaction engineering and separation processes for converting lignin from spent liquors into added-value aldehydes. The major result is an integrated process of vanillin production from Kraft lignin. The integrated process is based on three main steps. The first step consists on the alkaline lignin oxidation, in which valuable information can be found to decide the best conditions for the vanillin production. Considering the further isolation of vanillate from the oxidized solution, important results have been reached in the framework of ultra-filtration process, and equilibrium and kinetic adsorption studies. The degraded lignin resulting from membrane process can be considered for obtaining lignin-based polyurethanes materials. | por |
