This study reports the hydrothermal liquefaction (HTL) of microalgae Spirulina platenesis in presence alcohol or formic acid co-solvents. HTL runs are performed a 1.8-L batch reactor at 300 °C using an (methanol and ethanol) co-solvent. Consequently, hydrodeoxygenation (HDO) resultant algal biocrude is 350 for 2 h under high hydrogen pressure (~725 psi) Ru/C catalyst. The results compared with ...

Si recycling from powder waste is of great significance to the production profits and alleviate hazardous effects on ecological environment. Solvent refining an effective way reproduce solar-grade silicon (SoG–Si) by reusing waste. Herein, a Si–Sn–Cu ternary solvent with Zr-assisted method was proposed make full use high activity coefficients B strong affinity Zr. The at different compositions ...

Berry fruit by-products are a source of polyphenol compounds and highly nutritious oils can be reused to fulfill the requirements circular economy model. One methods obtaining polyphenol-rich extracts or is extraction. Applying conventional solvent extraction techniques may insufficient reach high lipid fraction yields selectivity specific compounds. Alternative methods, mainly ultrasound-assis...

Thermosetting polymers with permanent crosslinking networks have been intensively used in high-performance applications requiring thermal stability, chemical resistance, and structural integrity. However, they are extremely hard to be reprocessed recycled using conventional techniques. The recently developed solvent-assisted recycling technique is shown depolymerize recycle thermoset wastes low...
