本研究旨在研究负载金属的ZSM-5（Si/Al = 40）沸石在热解生物油的催化改质有机相的最终性质中的作用。因此，已经测试了几种阳离子，例如Mg、Ni、Cu、Ga和Sn。为了评估其作为潜在的液体燃料的应用，分析了几种性质，如pH、TAN、水含量、粘度、密度、高热值、氧含量，并通过GC/MS色谱法对不同化合物进行了半定量分析。结果表明，该液体在降低粘度和氧含量、提高高热值、减少酸性化合物和增加芳烃馏分方面有显著改善。在所测试的所有催化剂中，Ni-ZSM-5和Sn-ZSM-5被证明是热解生物油催化改质的潜在候选者。
The present investigation is aimed to study the effect of metal-loaded ZSM-5 (Si/Al = 40) zeolites in the final properties of a catalytically upgraded organic phase of pyrolysis bio-oil. Thus, several cations such as Mg, Ni, Cu, Ga and Sn have been tested. To evaluate its application as a potential liquid fuel, several properties such as pH, TAN, water content, viscosity, density, high heating value, oxygen content have been analyzed and a semi-quantitative analysis of the different compounds has been carried out by GC/MS chromatography. The results have pointed out a significant improvement of the liquid in terms of lower viscosity and oxygen content, higher high heating value, a decrease of the acidic compounds and an increase in the aromatic fraction. Among all the catalysts tested, Ni-ZSM-5 and Sn-ZSM-5 have demonstrated to be potential candidates in the catalytic upgrading of pyrolysis bio-oil.
