The influence of process conditions (rotary speed/temperature) on the performance of a rotary kiln reactor for non-catalytic pyrolysis of a perennial grass (elephant grass) was investigated. The product yields, the production of non-condensable gases as well as the biochar properties were evaluated. The maximum H2 yield was close to that observed for catalytic pyrolysis processes, while the bio-oil yield was higher than reported for pyrolysis of other biomass in rotary kiln reactors. A H2/CO ratio suitable for Fischer-Tropsch synthesis (FTS) was obtained. The biochars presented an alkaline pH (above 10) and interesting contents of nutrients, as well as low electrical conductivity, indicating a high potential as soil amendment.
研究了工艺条件（转速/温度）对多年生草本植物（象草）非催化热解用旋转窑反应器性能的影响。评估了产物收率、不可冷凝气体的产生以及生物炭的性质。最大的氢气产率接近催化热解过程中观察到的氢气产率，而生物油的产率高于在旋转窑反应器中热解其他生物质的报告。获得了适合费托合成（FTS）的 H2/CO 比。生物炭具有碱性 pH 值（高于 10）和有趣的营养物质含量，以及低电导率，表明其作为土壤改良剂具有很大的潜力。
