2022, Fluid Phase EquilibriaCitation Excerpt :Levulinic acid (LA) is a multipurpose platform molecule [1] that is obtained from the hydrolysis of cellulose [2–4], which is a source of other important biomolecules used to replace those derived from fossil resources [5–9]. One of the production routes to obtain LA is the catalytic hydrolysis of lignocellulosic biomass [10], the dehydration reaction of fructose or glucose [11], or directly from rehydration reaction of 5-hydroxymethylfurfural (HMF) using a mineral acid catalyst [12,13], whose result is an aqueous solution containing LA and formic acid (FA) [14–16]. The subsequent step is the selective separation of LA from FA, which is challenging because the chemical structure of these two organic acids is similar as both exhibit a carboxylic acid group, with the keto group present in LA and the number of carbons being the two main differences between them.

2021, Applied Catalysis B: EnvironmentalCitation Excerpt :Fig. 4 presents a schematic illustration of the representative application of SACs in biomass valorization reactions and highlights their individual characteristics. HDO reactions are effective in oxygen removal from selected biomass-derived compounds [241,242], and have been widely applied for many biomass-related technologies, including bio-oil hydrotreating [243], hydrogenolysis of alcohols and carbonyls [244], hydropyrolysis [65,245], aqueous-phase reforming of carbohydrates [43,246], and hydrotreating of organics acids [247], Typical HDO reactions involve oxygen-containing functional groups such as CcOH or COC in phenolics, furans, alcohols, aldehydes, acids, etc [62]. HDO can remove oxygen from lignin-derived phenolic compounds [243,248].
