Stearic acid/expanded graphite composites with different mass ratios were prepared by absorbing liquid stearic acid into the expanded graphite. In the composite materials, the stearic acid was used as the phase change material for thermal energy storage, and the expanded graphite acted as the...

Lignocellulosic biomass, microalgae and sewage sludge have distinct compositions and structures to each other. To understand the effect of feedstock differences on biomass liquefaction process, the liquefaction characteristics of rice straw (lignocellulosic biomass), Spirulina (microalgae) and...

The effect of different organic solvents, such as methanol, ethanol and 1,4-dioxane, on thermochemical liquefaction characteristics of Spirulina (a kind of high-protein microalgae) was systematically studied. The liquefaction experiments were conducted in a 1000 mL autoclave at different...

Liquefaction bio-oil from sewage sludge using different organic solvent (methanol, ethanol or acetone) at temperature of 260–380 °C was characterized in terms of its elemental and chemical composition, and was further upgraded by microemulsion technology. The bio-oil obtained had high carbon...
