文章采用实验室规模的固定床反应器作为实验平台,对蓝藻快速热解液化制取生物油的可行性进行了探讨,并对影响液化性能的诸多因素,如热解温度(300~700℃)、载气流量(0~400 mL/min)、原料粒径(d<0.08 mm,0.153.35 mm)和不同原料配比(蓝藻与秸秆粉混合)进行了分析和讨论。结果表明:当热解温度为500℃、粒径小于0.08 mm、载气流量为100mL/min时,热解产物中生物油产率最大,为54.97%(wt%),热值达31.9 MJ/kg,通过成分分析表明水华蓝藻是生产生物油的良好候选材料。
In this paper, a laboratory-scale fixed-bed reactor was used as an experimental platform to investigate the feasibility of rapid pyrolysis liquefaction of cyanobacteria to produce bio-oil. Many factors influencing liquefaction, such as pyrolysis temperature (300 ~ 700 ℃) , Carrier gas flow rate (0-400 mL / min), particle size (d <0.08 mm, 0.15 3.35 mm) The ratio of raw materials (mixture of cyanobacteria and straw powder) were analyzed and discussed. The results showed that when the pyrolysis temperature was 500 ℃, the particle size was less than 0.08 mm and the carrier gas flow rate was 100 mL / min, the yield of bio-oil in pyrolysis products was the highest (54.97% (wt%)) and the calorific value reached 31.9 MJ / kg, indicating that algal bloom is a good candidate for bio-oil production.
