Abstract

The paper studied the effects of Fe₃O₄ nanoparticles loaded biomass-derived carbon (Fe₃O₄/GLC) from ginkgo leaf on catalytic pyrolysis of heavy oil for the first time, and which was synthesized via green and low-cost ball milling method. The properties of Fe₃O₄/GLC were characterized by XRD, SEM, EDS, TEM, XPS. The experimental results showed that the viscosity of heavy oil may be decreased by 79.06% under optimal pyrolytic conditions of 350°C, 30 min and 0.05 wt % catalyst, and the viscosity reduction rate increased by 18.93% compared with pyrolysis alone. The property of the used catalyst was consistent with the new catalyst by XRD analysis. It was suggested that the catalyst had high activity and high stability for catalytic upgrading and viscosity reduction of heavy oil.

Fe3O4/GLC纳米复合材料对重油热解的催化作用

摘要

首次研究了负载Fe ₃ O ₄纳米颗粒的银杏叶生物质衍生碳（Fe ₃ O ₄ /GLC）对催化热解重油的影响，并通过绿色低成本球磨法合成。方法。Fe ₃ O _4的性质/GLC通过XRD、SEM、EDS、TEM、XPS进行表征。实验结果表明，在350 ℃、30 min和0.05 wt %催化剂的最佳热解条件下，稠油粘度可降低79.06%，与单独热解相比，粘度降低率提高18.93%。经XRD分析，所用催化剂的性质与新催化剂一致。表明该催化剂对稠油的催化改质和降粘具有高活性和高稳定性。
