Abstract

In order to enhance the deoxidation effect of low-temperature torrefaction and reduce the emission of CO2 during torrefaction, enhanced torrefaction experiments (220, 250and 280 °C) with Mg(OH)2 as additive were carried out on vertical furnace and thermogravimetric analyzer respectively. The results both showed that Mg(OH)2 effectively enhanced the deoxidation effect. Compared with T220, the O/C ratio of T0.5220, T1220 and T2220 decreased by 19.78%, 21.00% and 17.28%, respectively, O/C also decreased significantly at 250 °C and 280 °C. The mass ratio of Mg(OH)2 had little effect on the deoxidation effect. In addition, Mg(OH)2 could effectively adsorb CO2, thus reducing CO2 emissions. Among them, the CO2 emissions of T2220 was only about 1/2 of that of T220 during torrefaction.
