摘要/Abstract

摘要： 对95增碳剂(0.10%N)、石油焦(0.93%N)和沥青焦(0.40%N)进行煅烧脱氮试验，试验结果表明：随煅烧温度的提高，3种增碳剂中的氮含量都下降，温度大于2000 ℃时，各增碳剂中的氮含量均小于 100×10^-6 。1800℃煅烧时，95增碳剂的氮含量小于300×10^-6,石油焦或沥青焦的氮含量小于100×10^-6。

Abstract: The experiment on calcined denitriding process of recarburizer 95(containing 0. 10%N),petroleum coke(0.93%N)and pitch coke(0.40% N)has been carried out. The results indicated that with increasing cal- cined temperature the nitrogen content in 3 kinds of recarburizer decreased and as the temperature was more than 2000℃,the nitrogen content in each recarburizer was less than 100×10^-6.As calcined temperature was 1800℃, the nitrogen content in recarburizer 95 was less than 300×10^-6 while that in petroleum coke or pitch coke was less than 100×10^-6.
