Enhanced thermodynamic modelling for hydrothermal liquefaction
Fuel, 2021Abstract Hydrothermal liquefaction is a promising technology to produce drop-in biofuels from wet biomasses. In this paper a thermodynamic analysis, including chemical equilibrium and gas–liquid equilibrium in high-pressure conditions was conducted. The chemical equilibrium model is based on the minimization of the Gibbs free energy, while the high ...

Hydrothermal Liquefaction of Biomass for Chemicals
2016The production of liquid bioenergy carriers and chemicals from biomass can be realised by using hydrothermal conversion processes. Especially wet biomass is suitable for this kind of treatment as water is the reaction medium. A two-stage hydrothermal process was developed including first conversion of the biomass into liquid products and secondly ...

Hydrothermal Liquefaction of Bacteria and Yeast Monocultures
Energy & Fuels, 2013We hydrothermally treated monocultures of Escherichia coli, Pseudomonas putida, Bacillus subtilis, and Saccharomyces cerevisiae at isothermal (350 °C for 60 min) and fast (rapid heating for 1 min) liquefaction conditions. Fast hydrothermal liquefaction (HTL) of P. putida and S. cerevisiae produced the highest biocrude yields of 47 ± 13 and 48 ± 9 wt %,

Hydrothermal Liquefaction and Gasification of Nannochloropsis sp.
Energy & Fuels, 2010We converted the marine microalga Nannochloropsis sp. into a crude bio-oil product and a gaseous product via hydrothermal processing from 200 to 500 °C and a batch holding time of 60 min. A moderate temperature of 350 °C led to the highest bio-oil yield of 43 wt %. We estimate the heating value of the bio-oil to be about 39 MJ kg−1, which is comparable

Hydrothermal Liquefaction and Pyrolysis for Biofuel Production
Biofuels are extracted from renewable resources, they biodegrade naturally, are harmless to stockpile and are convenient for transportation. In addition, greenhouse gas emissions from biofuels into the environment are lower as compared to conventional fuels.Arti Maurya +2 more
