Abstract Effects of equivalence ratio (ER = 0.15, 0.25, and 0.35 at 934 °C) and temperature (790, 934, and 1078 °C at 0.25 ER) were investigated in air gasification of pine for primary gases and contaminants. CO and H2 increased while CO2 and CH4 decreased from 790 to 1078 °C. Opposite trends were observed for ER. Based on overall contaminant weight, tar was highest at all temperatures (7.81, 8.24, and 8.93 g/kg dry biomass) and ERs (13.08, 8.24, and 2.51 g/kg dry biomass). NH3 varied from 1.63 to 1.00 g/kg dry biomass between 790 and 1078 °C and from 1.76 to 1.47 g/kg dry biomass between 0.15 and 0.35 ER. H2S ranged between 0.13 and 0.17 g/kg dry biomass from 790 to 1078 °C and between 0.154 and 0.18 g/kg dry biomass from 0.15 to 0.35 ER. Finally, HCl yields ranged from 13.63 to 0 mg/kg dry biomass and from 11.51 to 0.28 mg/kg dry biomass over the range of temperature and ER, respectively.
