The 350 °C and 700 °C corn straw biochars were used to produce solid fuel briquettes. NovoGro (NG), an industrial by-product, were selected as a binder in the briquetting process. The ratios of the raw material to NG was assumed as 100:1 and 50:1 (denoted as 350NB₁, 350NB₂, 700NB₁ and 700NB₂, respectively). The physicochemical and morphological properties, combustion characteristics and gas emissions of the four briquettes were investigated. The results revealed that the biochars and the NG binder performed a good combination. The low temperature biochar briquettes, especially 350NB₂, had excellent combustion characteristics, including low H/C and O/C ratios (0.17 and 0.82), low gas emissions (104.06 mg/m³ of CO, 157.25 mg/m³ of NO_x and 18.92 mg/m³ of SO₂), optimal resistance to mechanical shock (~90%) and high calorific values (21.48 MJ/kg). Thus, NG is a good binder for the briquetting of biochar. The low temperature biochar was a good feedstock for solid fuel production in the improvement of the combustion and emission quality.

350°C和700°C的玉米秸秆生物炭用于生产固体燃料团块。在压块过程中，工业副产品NovoGro（NG）被选作粘合剂。原料到NG的比例假定为100：1和50：1（表示为350NB ₁，350NB ₂，700NB ₁和700NB ₂，分别地）。研究了四种团块的理化形态，燃烧特性和气体排放。结果表明，生物炭和NG粘合剂表现出良好的结合。低温生物炭团块，特别是350NB ₂，具有出色的燃烧特性，包括低的H / C和O / C比（0.17和0.82），低的气体排放（104.06 mg / m）³的CO，157.25 mg / m ³的NO _x和18.92 mg / m ³的SO ₂），最佳的抗机械冲击性（〜90％）和高发热量（21.48 MJ / kg）。因此，NG是生物炭团块的良好粘合剂。低温生物炭是改善燃烧和排放质量的固体燃料生产的良好原料。
