Find out how to produce

According to the new process, ceramics were used instead of carbon in the positive electrode. Therefore, instead of emitting CO ₂ , the reaction was given . pure oxygen.

Aluminum is the third most common element (after oxygen and silicon), and the most common metal accounts for 8.3% of the earth's composition. For a long time, aluminum has been used by humans in the manufacture of transport vehicles, in architecture, in kitchen appliances.

Interestingly, when it was discovered, due to its brightness and not being tarnished like silver, aluminum had been manipulated by Emperor Napoleon III of France into a table set of fork utensils instead of gold!

According to the new process at Elysis, ceramics were used instead of carbon in the positive electrode.

And now, along with aluminum alloys, this is a very important component in the aerospace and aerospace industry.

However, aluminum is not pure ore but is mixed in bauxite ore, so to obtain aluminum must be prepared, but the current popular method is electrolysis . The only thing is that when the ore is melted, its ions move freely and eventually, at the anode (anod), carbon is consumed by the reaction of O ₂ + C to release CO ₂ .

Statistics show that the aluminum industry alone "contributes" to 1% of greenhouse gas emissions from the global industry. So for many years, this is a challenge for scientists.

But the good news is that recently the Alcoa metallurgical group of the United States, in collaboration with the giant corporation specializing in mining of Rio Tinto in the UK and Australia, has used a new material instead of carbon to zero CO emissions. ₂ .

In fact, taking care of this process is Elysis company. According to the process, bauxite ore must be subjected to extremely strong currents to produce redox reactions. And by using carbon, it has created a reaction to release CO2. But according to the new process at Elysis, people used ceramic instead of carbon in the positive electrode. So instead of carbon dioxide, this time the reaction is . pure oxygen.

According to Vincent Christ, director of Elysis, with the process of using this new material, production capacity increased by 15% while production costs were lower. The factory is currently being built at Jonquiere (Quebec, Canada) and is expected to be put into operation in 2024.
