摘要

本研究的重点是在实验室规模的38ºC下，通过添加不同剂量的合成氧化铁纳米颗粒(30毫克/升、60毫克/升、90毫克/升和120毫克/升)对压浆进行厌氧消化，从而增强沼气的产生。利用x射线衍射和傅里叶变换红外光谱对氧化铁纳米颗粒进行了表征。结果表明，在含90 mg/L氧化铁纳米颗粒的压泥沼气池中，沼气产量达到245 ml。动力学建模结果表明，修正的Gompertz模型和修正的Logistic模型与累积产气量实验曲线拟合良好，相关系数(R2)分别在0.9969 ~ 0.9986和0.9987 ~ 0.9995之间

BIOENERGY TRANSFORMATION OF PRESS MUD VIA ANAEROBIC DIGESTION USING IRON OXIDE NANOPARTICLES: AN ANALYSIS

This study focuses on intensifying biogas production through anaerobic digestion of press mud with the addition of synthesized iron oxide nanoparticles at various doses (30 milligrams per liter, 60 milligrams per liter, 90 milligrams per liter, and 120 milligrams per liter) at 38C in a laboratory-scale. The characterization of iron oxide nanoparticles was done using X-ray Diffraction and Fourier Transform Infrared Spectroscopy. Results revealed that the peak of biogas production reached 245 ml in the digester containing press mud with 90 mg/L of iron oxide nanoparticles. The kinetic modeling reveals that the modified Gompertz model and modified Logistic models fit excellently with the experimental curve of cumulative biogas production, with correlation coefficient (R2) values ranging from 0.9969 to 0.9986 and from 0.9987 to 0.9995, respectively
