Understanding coal/hydrocarbons pyrolysis in thermal plasma reactors by thermodynamic analysis

▸ Performed theoretical analysis of coal/hydrocarbons pyrolysis in plasma reactor. ▸ Determined two key factors: the effective mass ratio of C/H and quench temperature. ▸ Justified the sensitivity of C2H2 yield to the quench temperature at 1500-1800 K. ▸ Enabled to evaluate the quench temperature based on the product gas composition. ▸ Proposed an effective way to adjust the reactor performance by additional hydrocarbon.
