Abstract The effect of pH and extraction temperature on flux, recovery, mass transfer coefficient separation factor volatile fatty acids (VFAs) alcohols from synthetic solutions cheese whey fermentate was investigated using a silicone membrane contactor with water as extractant. allowed undissociated only, resulting in substantially higher recovery efficiencies at 3 than 5. Furthermore, the non...

Magnesium is considered as a potential material for the separation of hydrogen from different gas streams (CH4/H2, syngas, natural gas, etc.). Herein, an elemental mixture Mg and Ni (5 wt%) used selective absorption CH4/H2 (90:10) at 350 °C. The performed studies (X-ray diffraction, thermogravimetric analysis, differential scanning calorimetry, chromatography) show that analyzed absorbs 4.5 wt%...
