Summary: Hydrothermal carbonization (HTC) and hydrothermal liquefaction (HTL) are two distinct processes differentiated by the reaction temperatures. Solvents are commonly used to extract bio-oil and separate the primary char and secondary char. Lipid hydrolysis begins at around 220 degrees C and is complete at 250 degrees C and above. Lower HTL temperature reduces energy cost and maximizes lipid hydrolysis, resulting in liquid fuel precursors with up to 70% energy recovery.

Summary: Hydrothermal liquefaction (HTL) is considered an effective technology for biooil production, with algae biomass being recognized as one of the most suitable feedstocks. The choice of temperature, retention time, and catalyst significantly affect the efficiency of HTL products, with a temperature range around 280 +/- 40 degrees C being reported as the most suitable for maximum bio-oil yield. Both homogeneous and heterogeneous catalysts have been used to improve bio-oil generation, with heterogeneous catalysts preferred for their advantages such as improved bio-oil yield, easy recovery, and eco-friendly approach.

Summary: This study conducted a direct observation of CO2 capture efficiency in the cultivation of microalgae Arthrospira platensis at high CO2 concentrations. The microalgae were grown in a 90 L photobioreactor using Zarrouk's medium. Three experiments were carried out with different initial CO2 concentrations: 1, 5, and 9 vol.%. The decrease in CO2 concentration due to microalgae growth was highest at 0.10 vol.% (CO2)/day in the experiment with an initial CO2 concentration of 5 vol.%. The biomass density growth rate was 79.4, 76.3, and 48.4 (mg/L)/day at 1, 5, and 9 vol.% CO2 concentrations, respectively. The viability of Arthrospira platensis was found to be good at 1% and 5% CO2 concentrations, but mass death of cells occurred at 9% CO2 concentration. Biochemical analysis showed a decrease in lipid and protein content with increasing CO2 concentration.

Summary: Composite materials were prepared by high energy ball milling of mixed scrap of Mg-based alloys and low melting point Sn-Pb eutectic, and their hydrogen generation performance was tested in NaCl solution. The effects of ball milling duration and additive content on microstructure and reactivity were investigated. SEM analysis showed significant structural transformations during ball milling, and XRD analysis confirmed the formation of new intermetallic phases Mg2Sn and Mg2Pb to enhance galvanic corrosion of the base metal. The reactivity of the material exhibited a non-monotonic dependency on activation time and additive content. Among all tested samples, milling for 1 hour and a composition with 5 wt.% Sn-Pb alloy showed the highest hydrogen generation rates and yields compared to other conditions.
