Evaluation of Storage Stability for Biocrude Derived from Hydrothermal Liquefaction of Microalgae
نویسندگان
چکیده
The instability of hydrothermal liquefaction (HTL) biocrude has impeded the broader utilization fuel and chemical feedstock. In this paper, we investigated storage stability produced from HTL microalgae. showed good in phase homogeneity water content, whereas viscosity average molecular weight increased by 48.4 41.9%, respectively, after storing for 12 months. Thermogravimetric analysis (TGA) asphaltene content indicated more high-boiling-point fraction, fraction appeared during storage. Further elemental total acid numbers (TANs) demonstrated that oxidization acidic-compound-forming reactions occurred, gas chromatography–mass spectrometry (GC–MS) results evidenced guess. However, mechanism still needs further analysis. current assuredly requires stabilization refining future applications.

Characterizing Semivolatile Organic Compounds of Biocrude from Hydrothermal Liquefaction of Biomass
Hydrothermal liquefaction of biomass produces a complex biocrude, which can be further upgraded to biofuel or chemicals, but there is a need for improved molecular understanding of product composition and reaction pathways. This study extensively characterizes semivolatile compounds in biocrudes from hydrothermal liquefaction (HTL) of microalgae (N. gaditana, C. vulgaris), macroalgae (L. hyperb...
متن کاملHydrothermal liquefaction of microalgae over transition metal supported TiO2 catalyst
Hydrothermal liquefaction (HTL) of microalgae Nannochloropsis (NAS) over various transition metal M/TiO2 (M = Fe, Co, Ni, Mo, and Mn) was investigated. Ni/TiO2 was the most effective catalyst to improve the yield and quality of biocrude and the liquefaction conversion. Ni/TiO2 was characterized by XRD, XRF, and XPS. The research of Effect of reaction temperature on HTL of NAS over Ni/TiO2 sugge...
متن کاملMicrobial utilization of aqueous co-products from hydrothermal liquefaction of microalgae Nannochloropsis oculata.
Hydrothermal liquefaction of algae biomass is a promising technology for the production of sustainable biofuels, but the non-oil, aqueous co-product of the process has only been examined to a limited extent. The aqueous phase from liquefaction of the alga Nannochloropsis oculata (AqAl) was used to make growth media for model heterotrophic microorganisms Escherichia coli, Pseudomonas putida, and...
متن کاملBiomass-to-biocrude on a chip via hydrothermal liquefaction of algae.
Hydrothermal liquefaction uses high temperatures and pressures to break organic compounds into smaller fractions, and is considered the most promising method to convert wet microalgae feedstock to biofuel. Although, hydrothermal liquefaction of microalgae has received much attention, the specific roles of temperature, pressure, heating rate and reaction time remain unclear. We present a microfl...
متن کاملChemical properties of biocrude oil from the hydrothermal liquefaction of Spirulina algae, swine manure, and digested anaerobic sludge.
This study explores the influence of wastewater feedstock composition on hydrothermal liquefaction (HTL) biocrude oil properties and physico-chemical characteristics. Spirulina algae, swine manure, and digested sludge were converted under HTL conditions (300°C, 10-12 MPa, and 30 min reaction time). Biocrude yields ranged from 9.4% (digested sludge) to 32.6% (Spirulina). Although similar higher ...
