- •
Particulate formation during co-firing of semi-char with lignite was investigated.
- •
Semi-char has less volatile content and more porous structure than parent lignite.
- •
Pure combustion of semi-char produces less fine particulate matter than lignite.
- •
Co-firing of semi-char with lignite results in fine particulate matter reduction.
- •
Volatile species is scavenged by porous char during early devolatilization stage.
