Abstract

Abstract: The present work focuses on process design and techno‐economic assessment of the oxidation of a pentose sugar present in hemicelluloses, i.e., arabinose, on a supported gold catalyst. The processing plant was designed with Aspen Plus. The arabinose feedstock price has an important impact on the operational performance contributing to almost half of these costs. The feasibility of the overall arabinose oxidation process requires efficient extraction of hemicellulose from the lignocellulosic biomass lowering the feedstock costs. Abstract : Process design and techno‐economic assessment was done for selective arabinose oxidation on a supported gold catalyst. The profitability is strongly influenced by the operating costs, which are highly dependent on the arabinose feedstock. The feedstock price has an important impact on the performance requiring efficient extraction of hemicellulose from the lignocellulosic biomass.
