选用60~100目的松木粉在流化床上进行快速热解实验,在反应温度550℃及载气流量3 m3/h的条件下,热解产物中油相18.7%,水相15.9%,焦炭46.2%,气相19.2%(质量分数)。对生物油进行理化特性及元素分析,利用气相色谱-质谱联用仪对生物油成分进行定性分析。将收集的生物油进行催化裂化改质,改质生物油收率为42.81%,其中轻质芳香烃(苯、甲苯、二甲苯、萘)含量达61.13%。
The pyrolysis experiments were carried out on a fluidized bed with 60 ~ 100 mesh pine wood powder. The pyrolysis products had an oil phase of 18.7%, an aqueous phase of 15.9% and a coke of 46.2 at a reaction temperature of 550 ° C and a carrier gas flow rate of 3 m3 / h %, Gas phase 19.2% (mass fraction). Bio-oil physical and chemical properties and elemental analysis, the use of gas chromatography-mass spectrometry qualitative analysis of bio-oil composition. The collected bio-oil was modified by catalytic cracking. The yield of modified bio-oil was 42.81%, in which the content of light aromatic hydrocarbons (benzene, toluene, xylene, naphthalene) reached 61.13%.
