Medicago sativa (alfalfa) is a widely used animal feed. However, its quality has been difficult to control due the lack of appropriate marker compounds. Therefore, it very necessary select an (Q-marker) quality. In this study, medium-pressure liquid chromatography and high-pressure were employed effectively prepare separation Q-marker (L-tryptophan) from sativa. Firstly, using MCI GEL® CHP20P a...

Due to the high versatility of Polyurethane (PUR), its share amongst synthetic polymers manufacture consumer goods is increasing. This study proposes, tests and validates through pilot processing a highly efficient method for carbon recovery PUR in form an oil phase concentrated using hydrothermal liquefaction (HTL). Hot liquid water mixed with residues lignocellulosic material (two species Mis...
