Abstract
Quinoa is a pseudo-cereal employed to provide nutrition and sustenance for a long time.
Currently, the consumption of seeds of this plant is increasing. The seed are the only nutritionally
part, which implies that both the husks like the rest of biomass represent a residue vaguely
studied. Authors had studied the thermal behavior of these quinoa inedible parts. Fuel
properties, biomass composition and DTG profiles were done for an oxidative atmosphere under
different heating rates in the same way that several characteristic combustion indexes were
estimated. Also, DTG profiles for a non-oxidative environment together with the
characterization of the char obtained were showed. Results denoted that quinoa biomass
presented a more suitable nature for combustion process compared with the husks.
Furthermore, combustion DTG profiles showed two different stages: devolatilization and
ignition. The maximum combustion weight loss value (20.63 %/min) was achieved for biomass
under a 40 K/min rate. DTG profiles under inert atmosphere evidenced two weight loss stages
clearly influenced by the cellulose and lignin content. Once again, biomass was the one with the
better behavior instead of the husk for this pyrolysis process. Biomass which had good values in
terms of yield (26.02 %) and heating value (15.41 MJ/kg).
