[0042] Example 1:
[0043] Such as figure 1 As shown, the cathode of electrolytic cell 2 is a Ni-Co-Fe alloy electrode, and the anode is a Ni-Rh alloy electrode. The composition of the alkaline electrolyte is: 1mol / L KOH, 1mol / L NH 3 . The ammonia in the alkaline electrolyte is supplemented by industrial ammonia water. Such as figure 2 As shown, the alkaline electrolyte prepared in the electrolyte supply system 1 is injected into the electrolytic cell 2, and an electrolytic reaction occurs at an applied voltage of 0.8V, and a high purity with a purity of 99.9% is produced at the cathode of the electrolytic cell 2 Hydrogen produces nitrogen and water with low ammonia content at the anode of the electrolytic cell 2. The high-purity hydrogen produced at the cathode of the electrolytic cell 2 enters the coal liquefaction system 3, and undergoes a hydrogenation catalytic reaction with coal slurry at high temperature and high pressure to produce naphtha and diesel, which are separat...
