The role of polysaccharides and proteins in bio-oil production during the hydrothermal liquefaction of algae species

Abstract

In order to understand the effects of the major algal components-carbohydrates and proteins on the hydrothermal liquefaction (HTL) process of algae, the HTL of polysaccharides or proteins with lipids was performed at 220, 260, 300 °C, respectively.

In-depth study of bio-oil and biochar production from macroalgae Sargassum sp. via slow pyrolysis

“…6 The thermochemical route of biomass into energy is considered favourable due to its more efficient and cost-effective process. 7 The thermochemical route of biomass into energy can be performed by liquefaction, 8,9 gasication, [10][11][12][13] and pyrolysis. 14,15 Among the thermochemical processes, the most common method for biomass conversion into valuable chemicals and biofuels is pyrolysis owing to its energy-efficient and economical nature.…”

Sustainable Biotechnology Approaches Using Chlorella vulgaris's Biomass and Lipids as Biofuel Feedstock

“…For example, in an acidic medium, acid hydrolysis cleaves glycosidic bonds between glucose units, while in a basic medium, an OH-ion attacks the anomeric carbon. These variations illustrate the adaptable and complex chemistry of HTL, allowing for optimized biomass conversion into valuable products [104,105].…”

Spill Behavior, Detection, and Mitigation for Emerging Nontraditional Marine Fuels

“…Hydrothermal liquefaction oils (also known as "bio-crudes") are similar in appearance to bio-oils (Ramirez et al 2015, Yang et al 2019, Golakotaa et al 2018). However, they are less dense (as shown in Table 1) and will float on the water surface.…”
