The depletion of fossil fuels as well as the greenhouse gas emissions from fossil fuel use have led to growing interest in biofuel production from biomass. A new technology, thermo-catalytic reforming (TCR), is one of the contributing interests. TCR technology integrates intermediate pyrolysis with a post-reforming stage to convert biomass into a high-quality bio-oil, biochar, and syngas. In this study, experiments were carried out using three Alberta-based biomass feedstocks – hardwood pellets, softwood pellets, and chips – in a 2 kg h−1 laboratory-scale TCR plant. The results show that the composition of the biomass has little effect on product yield and quality. The TCR gases had a higher heating value of 12.5–12.8 MJ kg−1 and a hydrogen content of 13–15 vol %. The produced TCR bio-oil had low water content (~5 wt %) and a heating value of 32–34 MJ kg−1. The high quality of the bio-oil is reflected in the low O/C ratio of 0.15 and TAN of 6–15 mg KOH g−1. The TCR biochar from all three feedstocks had a high heating value and a high carbon content, as well as low O/C and H/C ratios. A parametric study was conducted for the softwood pellets to observe the effect of reformer temperature (500–700 °C) and reactor temperature (400–550 °C). It was observed that at a reformer temperature of 700 °C, the gas yield increases at the expense of a reduction in bio-oil and biochar. The optimum reactor temperature for the TCR of softwood pellets was found to be 500 °C, in terms of both bio-oil quality and yield.

基于艾伯塔省的生物质原料的热催化重整以生产生物燃料

化石燃料的枯竭以及化石燃料使用产生的温室气体排放导致人们对利用生物质生产生物燃料的兴趣日益浓厚。一项新技术,即热催化重整 (TCR),是其中之一。TCR 技术将中间热解与后重整阶段相结合,将生物质转化为高质量的生物油、生物炭和合成气。在这项研究中,使用三种基于艾伯塔省的生物质原料——硬木颗粒、软木颗粒和木片——在 2 kg h -1实验室规模的 TCR 工厂中进行了实验。结果表明,生物质的组成对产品产量和品质影响不大。TCR 气体具有更高的热值,为 12.5–12.8 MJ kg -1氢含量为 13–15 vol%。生产的 TCR 生物油含水量低(~5 wt%),热值为 32-34 MJ kg -1。生物油的高质量体现在 0.15 的低 O/C 比和 6–15 mg KOH g -1 的TAN 。来自所有三种原料的 TCR 生物炭具有高热值和高碳含量,以及低 O/C 和 H/C 比。对软木颗粒进行了参数研究,以观察重整温度 (500-700 °C) 和反应器温度 (400-550 °C) 的影响。据观察,在 700 °C 的重整器温度下,气体产量增加,但以生物油和生物炭的减少为代价。就生物油质量和产量而言,软木颗粒 TCR 的最佳反应器温度为 500 °C。
