Data on characterization of crude bio-oils, gaseous products, and process water produced from hydrothermal liquefaction of eight different algae

Abstract

The characterization of products produced from hydrothermal liquefaction of algal biomass is helpful to better understand the effect of different kinds of raw materials on the properties of the product fractions. The data presented in this article are related to the research article entitled “Integration of hydrothermal liquefaction and supercritical water gasification for the improvement of energy recovery from algal biomass” (Duan et al., 2018) [1]. In this data article, the compositions of gaseous products produced from hydrothermal liquefaction of eight different algae feedstocks at 350 °C for 60 min were analyzed by gas chromatography. The molecular and elemental compositions of the crude bio-oils produced from hydrothermal liquefaction of eight different algae feedstocks at 350 °C for 60 min were analyzed by comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry and organic elemental analyzer. The color of aqueous phases before and after they were subjected to supercritical water gasification was recorded by a high-resolution camera.

Hydrothermal Treatment of Biomass Feedstocks for Sustainable Production of Chemicals, Fuels, and Materials: Progress and Perspectives

“…The effects of algae types and temperature under HTL conditions were investigated to analyze the production of solid, liquid, and gaseous products. − Accordingly, HTL with high lipids content of algae at a high temperature (at 320 °C) produced the maximum bio-oil with a yield of around 66% . The solid residue exhibited attractive potential as solid fuels based on the HHV .…”

“…The solid residue exhibited attractive potential as solid fuels based on the HHV . The gaseous products includes H 2 , CO, CH 4 , and CO 2 , which are the common gaseous products obtained during HTL of lipids, proteins, and carbohydrates. , Additionally, the aqueous solutions (processing water) had a high amount of organics, nitrogen, and phosphate for reforming . To improve the carbon recovery, nitrogen recovery, and energy recovery of low-lipid algae during the HTL processing, Yu et al optimized the HTL conditions such as temperature and residence time .…”

Sustainable production of microalgae biomass for biofuel and chemicals through recycling of water and nutrient within the biorefinery context: A review

“…The EC 50 values for nitrogenous compounds are reported as low as ~0.05 mg/L and as high as 140 mg/L (Pham et al, 2013). A detailed investigation of organic compounds in the AP of HTL from eight microalgae is provided by Duan et al (2018; Yang, Xu, et al, 2018). Besides organic compounds, the presence of heavy metals is also detrimental to microalgal growth.…”

Comprehensive Two-Dimensional Gas Chromatography Advances in Technology and Applications: Biennial Update

“…With the increasing interest to find alternatives to fossil fuels, scientists are exploring a diverse range of replacements, and so, it is not surprising that applications of GC×GC in this field are growing. Recent work has explored the composition of bio-oils obtained from vegetable sources and waste products, such as algae, safflower, coffee waste, − rice husk, sugar cane residues, , and coconut fibers for fuel applications. Caramão and co-workers − , optimized the biomass pyrolysis procedure to obtain bio-oils from the last four sources cited above, using GC×GC to obtain their chemical profiles.…”
