原铝的生产规模居有色金属工业的首位,1990年我国铝锭的年产量约80万t。铝电解生产是耗能大的工业之一,每电解出1t铝耗电约15000～16000kw·h。目前,电解槽用炭质材料作阳极,其阳极超电压为0.4～O.6V,它占槽工作电压的10%～15%,造成了很大的电能浪费。我们利用电催化原理,在炭素阳极中掺入微量的催化剂——碳酸锂,提高阳极活性,加速反应过程,能降低阳极超电压150～200mv,如应用于工业生产,可节省电能为500～677kw·h/t.A1。 The production scale of primary aluminum ranks first in the nonferrous metal industry. In 1990, the annual output of aluminum ingots in China was about 800,000 t. Aluminum Electrolysis production is one of the industries with large energy consumption, each electrolytic 1t aluminum consumption about 15000 ~ 16000kw · h. At present, the electrolytic cell uses carbonaceous material as the anode, and the anode overvoltage is 0.4-0.6V, which accounts for 10% -15% of the operating voltage of the trough, resulting in a great waste of electric energy. We use the principle of electrocatalysis, carbon anode incorporation of a trace amount of catalyst - lithium carbonate to improve the anode activity and speed up the reaction process can reduce the anode over-voltage 150 ~ 200mv, such as used in industrial production, can save electricity for the 500 ~ 677kw · H / t.A1.
