- 摘要:
- Interaction mechanisms between iron and HCN are investigated in a fixed bed, compared with calcium and magnesium, and the original HCN is generated by pyridine pyrolysis. Results show that the interaction mechanism of HCN with Fe2O3 is totally different from CaO and MgO. Fe2O3 can transform HCN into NO, compared with that CaO and MgO convert HCN to N2. Under the effect of Fe2O3, HCN begins to decrease at 473K, and when temperature is higher than 623K, all HCN has been transformed. CH4 starts to decrease linearly at around 348K, disappearing at 623K, and CO increases continually from 348K. The reaction between HCN and Fe2O3 is suggested as 2Fe2O3+3HCN→2Fe +3CO+3NO+0.5H2. Fe formed in the reaction of HCN- Fe2O3 can further react with HCN to transform the nitrogen in HCN into N2. Fe starts to reduce HCN from 423K, when temperature is higher than 598K, HCN has been converted completely, and the nitrogen elements of N2 are balanced with that of inlet HCN.
