摘要
蓝藻含水率高达99%以上，采用热解等热化学处理方法时需要对蓝藻进行干燥预处理，能耗极高。针对该问题，对含水率92.94%的蓝藻进行水热碳化（HTC）处理，研究了水热温度（180~260 ℃）、保温时长（0~3 h）和升温速率（1 ℃/min和1 ℃/6 min）对水热炭燃料特性及燃烧行为的影响。结果表明，通过水热碳化处理，蓝藻挥发分含量降低了9.92%~29.13%，灰分含量提高了8.54%~25.52%，固定碳含量提高了0.82%~5.26%。蓝藻水热炭燃烧可分为干燥脱水、挥发分脱除以及挥发分和固定碳燃烧3个阶段。水热碳化处理提高了蓝藻的着火温度（505~583 K）和燃尽温度（747~812 K），更加有利于蓝藻储存和运输。动力学分析结果表明，挥发分脱除及其燃烧阶段为一级反应，活化能为27.82~66.04 kJ/mol；固定碳燃烧阶段为二级反应，活化能为38.65~65.68 kJ/mol。本研究可为蓝藻资源化利用提供参考。
Abstract
The moisture content of blue-green algae is over 99%. when using thermochemical treatment methods such as pyrolysis
it is necessary to dry and pretreat the blue-green algae
which consumes a high amount of energy. To address this issue
hydrothermal carbonization (HTC) was applied to blue-green algae with a moisture content of 92.94%. The effects of hydrothermal temperature (180 ℃ to 260 ℃)
holding time (0 h to 3 h)
and heating rate (1 ℃/min and 1 ℃/6 min) on the fuel properties and combustion behavior of the resultant hydrochar were studied. The results indicate that HTC treatment reduces the volatile content of algae by 9.92% to 29.13%
increases ash content by 8.54% to 25.52%
and enhances fixed carbon content by 0.82% to 5.26%. Combustion of hydrochar from blue-green algae occurs in three stages: dehydration
volatile release
and combustion of volatiles and fixed carbon. HTC treatment elevates the ignition temperature (505 K to 583 K) and burnout temperature (747 K to 812 K)
which improves the storage and transport properties of the material. Kinetic analysis shows that the volatile release and its combustion stage follows a first-order reaction with an activation energy of 27.82 kJ/mol to 66.04 kJ/mol
while the fixed carbon combustion stage follows a second-order reaction with an activation energy of 38.65 kJ/mol to 65.68 kJ/mol. This study provides a reference for the resource utilization of blue-green algae.
