On the reaction mechanism of the pyrolysis step in the process for producing sodium cyanide via light oil pyrolysis
Thread Content
While searching for papers recently, I came across a brief description of a process for producing hydrogen cyanide via light oil pyrolysis, which is then used to manufacture sodium cyanide. Among these, what interests me is the reaction mechanism of the pyrolysis step in this process. Since I conducted research on the pyrolysis of low-carbon organic compounds as part of my graduation thesis, I am also very interested in understanding the pyrolysis mechanism in light oil pyrolysis, as well as the reaction mechanism between the two substances involved (it’s not just a simple reaction equation). There must be factories in our country that use this method to produce sodium cyanide. I hope some friends who know the answer can help provide one; many hands make light work! ! Thank you! !

Ammonia and light oil, after being mixed and preheated, enter the pyrolysis furnace, which is a fluidized bed reactor lined with refractory bricks and equipped with electrodes, using petroleum coke particles as the heat carrier. After entering the pyrolysis furnace, the mixed gas undergoes a pyrolysis reaction at high temperatures above 1400°C, producing gases such as hydrogen cyanide, nitrogen, and hydrogen. The composition of the pyrolysis gas is as follows: 10–20% HCN, 60–70% H2, about 15% N2, and 0.5–1% NH3. The main reactions are as follows: Main reaction: C5H12 + 5NH3 → 5HCN + 11H2 – 1800 kcal/kg; Side reactions: NH3 + C → HCN + H2; C5H12 + C → C3H2 + 6H2; 2NH3 → N2 + 3H2
I am also working on the material balance and heat balance for this project. Since my understanding of this process isn’t very deep, I would really appreciate the help from those who are experienced in this field.:handshake
A pyrolysis reaction is carried out in an electric arc furnace using a mixture of light diesel and ammonia, with petroleum coke as a carrier and nitrogen to create an airtight environment to prevent oxidation. C6H14+6NH3=6HCN+13H2↑
I am working at a newly built sodium cyanide plant that uses light oil cracking.
Hey, my friend, can I talk to you? I also want to learn more about this area. 406793419qq
