基于NPSC的Zn/HZSM-5在线催化提质生物油的研究
Study on Online Catalytic Upgrading of Bio-Oil Using NPSC Based Zn/HZSM-5
摘要
Abstract
A non-thermal plasma synergistic catalytic system was established, which was used in bio-oil upgrading catalyzed by Zn/HZSM-5. Effects of three-way catalysis (including non-thermal plasma, HZSM-5 and a Zn modified component) on bio-oil quality and catalyst coking were analyzed. The results show that the three-way catalysis reduces the yield of refined bio-oil, but improves its physicochemical properties. Oxygen content, pH kinematic viscosity and gross caloric value are 16.45%, 5.00, 5.10 mm2?s-1and 34.25 MJ?kg-1, respectively. The synergistic action of non-thermal plasma discharge enhances the deoxidization performance of Zn/HZSM-5. Both content and composition of alkane in refined bio-oil are improved. Polycyclic aromatic hydrocarbons are significantly reduced and monocyclic aromatic hydrocarbons are increased. The coking resistance of Zn/HZSM-5 is enhanced, but low effective hydrogen to carbon ratio of reactants makes it difficult to have substantial improvement in catalytic stability. Therefore, it is necessary to evaluate raw material to improve hydrogen contents, which can be effectively transferred and utilized in the process of catalytic upgrading.关键词
