Corrigendum to “Extension of the chemical percolation devolatilization model for predicting formation of tar compounds as soot precursor in coal gasification” (Fuel Processing Technology (2017) 159 (256–265), (S0378382016309274), (10.1016/j.fuproc.2017.01.037))

The authors regret that there is a correction in the abstract; The details are as follows: ORIGINAL(Existing): In the original article published in 2017, errors were found in two equations in the Appendix. The calculations in the research were conducted by using correct equations below. Therefore, these errors do not change the scientific conclusions of the article. • Eq. A1: The original equation used (1/2 + 3/C_S) but correct one should use (1/2–3/C_S) as shown below. [Formula Presented] • Eq. A5: The original equation used Y_1-ring/Y_2-ring in four parts but correct one should use Y_2-ring/Y_1-ring as shown below. [Formula Presented] The authors would like to apologise for any inconvenience caused.
