An experimental characterization of crop residue biomass blends to evaluate their energy potential was conducted using an experimental approach in a commercial scale downdraft gasifier. Corncobs, rice husks, sesame stalks and cotton gin refuse were used to study the effect of mixture proportions on equivalence ratio, gasification temperature, syngas lower heating value (LHV), and cold gas efficiency (CGE). Using an experimental mixture design, thirty-two sample blends were evaluated in an Ankur WBG-30 downdraft gasifier with 30 kg/h feed supply coupled with a syngas purification system, temperature sensors and a gas chromatograph. Syngas composition CO, H₂, CH₄, N₂ and CO₂ are presented for each blend. It was found that temperature, syngas composition, syngas lower heating value and cold gas efficiency were negatively affected as the proportion of rice husks in the mixture was increased. It was possible to reach CGE values up to 57.91% and LHV up to 4460 kJ/kg under certain blending conditions. A higher percentages of rice husks caused a considerable increase in the variability of the equivalence ratio resulting in suboptimal gasification conditions.

在商业规模的下浮式气化炉中使用实验方法对农作物残余生物质混合物进行了实验表征，以评估其能量潜力。使用玉米芯，稻壳，芝麻秸秆和轧花渣来研究混合比例对当量比，气化温度，合成气低热值（LHV）和冷气效率（CGE）的影响。使用实验混合物设计，在Ankur WBG-30向下气流气化炉中，以30 kg / h的进料气量，合成气净化系统，温度传感器和气相色谱仪对32种样品混合物进行了评估。合成气成分CO，H ₂，CH ₄，N ₂和CO ₂每种混合都有。发现随着混合物中稻壳的比例增加，温度，合成气组成，合成气较低的热值和冷气效率受到不利影响。在某些混合条件下，CGE值最高可达57.91％，LHV最高可达4460 kJ / kg。较高的稻壳比例导致当量比的变化显着增加，导致气化条件欠佳。
