Kraft Lignin Conversion into Energy Carriers under the Action of Electromagnetic Radiation
Figure 5
(а) Temperature dependence of the magnetization (М) in a H = 39.8 kA/m field for initial (before the reforming) of samples 0.1 Fe/(kraft lignin) (○) and 0.1 Fe-1.5 Ni/(kraft lignin) (□) recorded in the FC and ZFC modes. The inset shows the М(Т) curves for samples 3, 6, and 7 measured in a H = 39.8 kA/m field; (b) M(H) curves for samples 3 and 6 at Т = 300 and 4 K after the reforming. The inset shows the hysteresis loops for low fields at Т = 300 and 4 K (residual Мr = 0.6 emu/g and Мr = 0.06 emu/g for 4 and 300 K, respectively; saturation Мs = 1.51 emu/g and Мs = 0.84 emu/g for 4 and 300 K, respectively).
