Seeking appropriate approaches to utilize the crude glycerol produced in biodiesel production is very important for the economic viability and environmental impacts of biodiesel industry. Gasification may be one of options for addressing this issue. Co-gasification of hardwood chips blending with crude glycerol in various loading levels was undertaken in the study involving a pilot scale fixed-bed downdraft gasifier. The results indicated that crude glycerol loading levels affected the gasifier's performance and the quality of syngas produced. When crude glycerol loading level increased, the CO, CH(4), and tar concentrations of the syngas also increased but particle concentration decreased. Though further testing is suggested, downdraft gasifiers could be run well with hardwood chips blending with liquid crude glycerol up to 20 (wt%). The syngas produced had relatively good quality for fueling internal combustion engines. This study provides a considerable way to utilize crude glycerol.
寻求合适的方法来利用生物柴油生产中产生的粗甘油对于生物柴油产业的经济可行性和环境影响非常重要。气化可能是解决这个问题的一种选择。本研究采用中试规模的下吸式固定床气化炉，对硬木片与不同负荷水平的粗甘油共气化进行了研究。结果表明，粗甘油负荷水平影响气化炉的性能和合成气的质量。随着粗甘油负荷水平的增加，合成气中的 CO、CH(4)和焦油浓度也增加，但颗粒浓度降低。尽管需要进一步测试，但下吸式气化炉可以很好地运行，硬木片与液体粗甘油混合比例高达 20（wt%）。所产生的合成气具有内燃机燃料的良好质量。本研究为利用粗甘油提供了一种可行的方法。
