“…Biocrudes produced during the HTL of biomass consist of a complex mixture of several compounds of different nature, including aldehydes, ketones, phenols, alkanes, fatty/carboxylic acids, and nitrogen compounds. 125 The presence and abundance of these species in the bio-crude are directly linked to the composition of the raw material and the reaction conditions (temperature, time, pressure and catalyst type and loading) used in the HTL process. The chemical determination of these species in the bio-crude is complex, as this liquid also contains some high mass weight compounds, primarily derived from lignin, that cannot be determined by Gas Chromatography (GC).…”

“…Hemicellulose is composed of xylose, mannose, and other monosaccharides. Its structure is uneven due to the abundant side chain groups, and can be easily dissolved and hydrolyzed above 180°C [27]. Lignin comprises three different types of phenylpropane structural units connected by C-O-C bonds and C-C bonds.…”

“…Based on experimental results from GC-MS and 1 H-NMR characterization, a general reaction network as well as predicted pathway schemes for HTL of lipids, proteins and non-fibrous carbohydrates in low-lipid microalgae were proposed [16]. A combination of predictive biocrude yield and reaction network study was performed by Yang et al [17]. The prediction model was developed using a mixture design of five model components and verified with results from actual feedstock and mixtures of model components.…”

“…In the present study, the generalized reaction concepts and predicted pathway schemes mentioned in literature are consolidated [15][16][17], and put into live in a comprehensive Aspen Plus ® simulation for three different feedstock. Fifty one model compounds are used as representatives of the biomass.…”
