Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
To understand the effect of inherent sulfur in coal on the formation of NO precursors during coal pyrolysis, the experiments for raw coal and desulfurised coal pyrolysis in argon atmosphere were conducted by using a drop-tube/fixed-bed reactor and IC analyzer. The results show that the yields of NH3 during raw coal pyrolysis are lower than those of desulfurised coal. This indicates that the existence of sulfur in coal can influence the formation of NH3 and HCN, which is approved by model compounds experiments. The results for nitrogen contained model compound (pyridine) and sulfur contained model compound (thiophene) pyrolysis show that formation of HCN and NH3 decreased during pyridine pyrolysis in the presence of thiophene.
