采用固定床反应器，在1073、1173和1273 K条件下，研究了气氛对稻秆热转化过程中碱和碱土金属（AAEM）物质转化的影响。考虑两种气氛：100% (v/v) N2模拟热解和1% (v/v) O2在N2平衡中模拟燃烧。通过对秸秆和固体残渣的质量测量和电感耦合等离子体（ICP）分析，采用质量平衡法定量测定了秸秆热解和燃烧过程中AAEM的释放量。通过水浸和1% HNO3洗涤对实验中得到的固体残渣和释放凝聚颗粒进行处理，并通过离子色谱（IC）分析，确定其中所含AAEM物质的可能化学形态。实验结果表明，氧化气氛通过促进炭中K2CO3和炭K的分解，促进了1073、1173和1273 K处K的释放。
The influence of the atmosphere on the transformation of alkali and alkaline earth metallic (AAEM) species during rice straw thermal conversion was investigated by a fixed-bed reactor at 1073, 1173, and 1273 K. Two types of atmospheres were considered: 100% (v/v) N2 to simulate pyrolysis and 1% (v/v) O2 in N2 balance to simulate combustion. The release of the AAEM species during pyrolysis and combustion of the rice straw was quantified by a mass balance based on the weight measurements and inductively coupled plasma (ICP) analysis of the rice straw and the solid residue. Solid residues and released and condensed particles obtained in experiments were processed by water leaching and 1% HNO3 washing and analyzed by ion chromatography (IC) to determine the possible chemical form of the AAEM species contained in them. The experimental results showed that the oxidizing atmosphere facilitated the release of K at 1073, 1173, and 1273 K by enhancing the decomposition of K2CO3 and char K in the char during the cha...
