We investigated the potential application of anaerobically digested residues for generating bioenergy in the presence of alkali bifunctional material, sodium zirconate (NaZrO, NZ) using a thermogravimetric analyzer connected to a mass spectrometer. Isoconversional kinetic models, compensation effect and master-plots method were used on data obtained under multiple heating rates (10, 15 and 20 °C min) to calculate the activation energy (E) and pre-exponential value (A) and reaction mechanism. The average E for blend samples C-DSW (NZ mixed with digested municipal solid waste (DSW)), and C-DSM (NZ mixed with digested swine manure (DSM)) were 172.24 and 171.63 kJ mol, which were much lower when compared to plain samples, DSW (202.51 kJ mol) and DSM (215.22 kJ mol). The total gas yields increased by 19.5 and 17.1% for NZ blended samples C-DSW and C-DSM, respectively. In addition, the hydrogen yields also increased by 79 and 44% for C-DSW and C-DSM, respectively.
我们使用热重分析仪与质谱仪联用，研究了在碱双功能材料氧化锆酸钠（NaZrO，NZ）存在的情况下，利用厌氧消化残余物生成生物能的潜力。我们使用等转化率动力学模型、补偿效应和主图法，对在多个加热速率（10、15 和 20°C/min）下获得的数据进行了分析，以计算活化能（E）和指前因子（A）和反应机制。混合样品 C-DSW（NZ 与消化后的城市固体废物（DSW）混合）和 C-DSM（NZ 与消化后的猪粪（DSM）混合）的平均 E 值分别为 172.24 和 171.63 kJ/mol，与纯样相比，DSW（202.51 kJ/mol）和 DSM（215.22 kJ/mol）的 E 值要低得多。NZ 混合样品 C-DSW 和 C-DSM 的总气体产率分别增加了 19.5%和 17.1%。此外，C-DSW 和 C-DSM 的氢气产率也分别增加了 79%和 44%。
