摘要：在HZSM-5催化剂存在的条件下,生物质裂解油在固定床反应器内进行了催化裂解. 实验研究了精制生物油的产率受温度、催化剂粒度、质量空速、溶剂诸因素的影响程度. 在较佳的反应条件下,即质量空速3.7 h-1、温度380oC时,获得了较高的精制生物油产率(44.68%). 产物分析表明,精制油中的含氧化合物如有机酸、酯、醇、酮、醛的含量大大降低,而不含氧的芳香族碳氢化合物和多环芳香碳氢化合物含量有所增加.
In preparation of motor fuel, bio-oil from pyrolysis of biomass must be further upgraded so as to improve its quality. Upgrading operation via catalytic cracking was carried out in a tubular fixed-bed reactor with HZSM-5 as catalyst, under atmospheric pressure, in the temperature range of 340~420oC, and at weight space velocity (WHSV) of 2.9~5.6 h-1. The effects of process parameters such as temperature, WHSV, solvent and size of catalyst pellets on product yield were studied. The results show that 44.68% (w) of organic distillate was yielded at temperature 380oC and WHSV=3.7 h-1. In addition, the analysis of upgraded oil shows that the amount of oxygenated compounds in the bio-oil, such as organic acid, aldehyde, ester, alcohol, ketone were greatly reduced meanwhile aromatic and polyaromatic hydrocarbons were formed.
