摘要: 热解能够实现油泥资源化利用,热解后的热解焦可以通过焚烧实现能量的梯级利用。利用热分析仪研究不同掺混比(φ)及不同升温速率(β)下的油泥热解焦与微藻渣混合燃烧实验,TG和DTG曲线表明,混合燃烧过程分为结晶水挥发、挥发分析出和燃烧、固定碳燃烧和矿物质燃烧分解。采用KAS和OFW等转化率法进行动力学参数求解。结果表明,添加微藻渣提高了混合燃料燃烧特性;β的增加促使传质阻力增大,质量损失段向高温区移动;活化能(Ea)值增大,燃烧稳定性提高。

Abstract: Pyrolysis can help resource utilization of oil sludge, and combustion of oil sludge pyrolysis char can optimize energy utilization. In this work, co-combustion experiments under different mix ratios (φ) of oil sludge and microalgae residues were carried out in a thermogravimetry system at different heating rates (β). TG and DTG curves indicate that co-combustion consists of different processes including moisture volatilization, volatiles release and combustion, fixed carbon combustion and minerals decomposition. KAS and OFW the isoconversional methods were applied to find kinetic parameters. Experimental results indicate that microalgae residues could improve combustion performance of the blended fuel.  A higher heating rate could cause a larger mass transfer resistance, with mass loss region moving to the high temperature range. A higher activation energy (Ea) could improve co-combustion stability.

Key words: oil sludge pyrolysis char, microalgae residue, co-combustion, kinetics, activation energy
