We synthesized manganese oxide(II) submicroparticles stabilized with oleic acid and used them as oil-dispersible catalyst precursor promoting a heavy oil oxidation process. Size, morphological properties, as well as composition of the catalyst were studied in depth by X-ray phase diffraction analysis, thermogravimetric–mass spectrometry analysis, scanning electron microscopy, energy dispersive X-ray analysis, and nitrogen adsorption measurements. We applied nonisothermal kinetic analysis coupled with an isoconversional approach to study the influence of catalyst on the combustion process and showed that Mn-based submicroparticles accelerate predominantly the high-temperature oxidation process.

石英多孔介质中锰基亚微粒存在下重油的催化燃烧

我们合成了用油酸稳定的氧化锰（II）亚微粒，并将其用作油分散性催化剂前体，促进了重油的氧化过程。通过X射线相衍射分析，热重-质谱分析，扫描电子显微镜，能量色散X射线分析和氮吸附测量，对催化剂的尺寸，形态学性质以及催化剂的组成进行了深入研究。我们应用非等温动力学分析和等温转化方法，研究了催化剂对燃烧过程的影响，结果表明，基于Mn的亚微粒主要促进了高温氧化过程。
