摘要: 针对生物油催化裂解提质工艺中存在催化剂易结焦失活、精制油品质低等问题,提出了低温等离子体(NTP)协同分子筛催化剂HZSM-5在线催化裂解提质油菜秸秆热解油的技术方案,采用自行设计的NTP辅助催化反应器,探讨了工艺参数对精制生物油得率和理化特性的影响。研究结果表明:催化温度、催化剂床层高度和反应器放电功率对反应结果影响显著,在催化温度400℃、催化剂(NTP+HZSM-5)床层高度35 mm、反应器放电功率25 W的最优工艺条件下,获得了精制生物油得率、含氧量、高位热值(QHHV)、pH值和重质组分分别为9.13%、15.78%、34.86 MJ/kg、5.41和3.15%的试验结果,与单HZSM-5催化提质方法相比,精制生物油品质显著提升,且催化剂积炭量从单HZSM-5提质方法时的5.88%大幅降低至2.14%,证实了NTP协同HZSM-5催化裂解提质生物油技术方案的可行性。

Abstract: Catalytic cracking is an efficient method for bio-oil upgrading. However, the catalyst was prone to coking and deactivating in upgrading process. This leads to the decrease of quality of upgrading bio-oil. Therefore, the non-thermal plasma(NTP) assisted catalytic cracking reactor with zeolite catalyst was designed. The effects of the operating parameters on yield and physicochemical properties of upgraded bio-oil were studied. Under the optimum operating parameters, i.e., the catalyst temperature of 400℃, catalyst bed height of 35 mm and reactor discharge power of 25 W, the yield of upgraded bio-oil, oxygen content, higher heating value(QHHV), pH value and heavy component were obtained as 9.13%, 15.78%, 34.86 MJ/kg, 5.41, 3.15%, respectively. In terms of thermal gravimetric analysis, the total coke amount on the surface of the catalyst decreased from 5.88% to 2.14% through the methodology of NTP assisted HZSM-5.
