磷化钨催化剂C5石油树脂加氢性能探索

采用共浸渍和氢气程序升温还原法, 以γ-Al₂O₃为载体，制备负载W质量分数30%（以WO₃计）的磷化钨催化剂，对催化剂进行XRD、BET、SEM和TG/DTA表征，考察催化剂的C₅石油树脂加氢反应性能，并研究助剂Ni和Co对催化剂结构和加氢反应活性的影响。结果表明，助剂的加入能改善催化剂表面活性组分的分散性和增加WP/γ-Al₂O₃催化剂的比表面积，对WP/γ-Al₂O₃催化剂活性组分与载体之间的相互作用也可能存在影响，Co或Ni对磷化钨催化剂C₅石油树脂加氢反应均有不同程度的改善作用。

Performance of tungstenphosphide catalysts with nickle and cobalt promoters for C5 petroleum resin hydrogenation

Using γ-Al₂O₃ as the support,Ni and Co as the promoters,WP catalysts loading with WO₃ mass fraction of 30% were prepared by impregnation and temperature programmed reduction method.The as-prepared WP catalysts were characterized by XRD,BET and TG-DTA.The reaction properties of WP catalysts for the hydrogenation of C₅ petroleum resin and the influence of Ni and Co promoters on the structure and hydrogenation activity of the catalysts were investigated in a high-pressure microreactor.The results showed that the addition of the promoters could improve the active component dispersion on the catalyst surface and increase the surface area of WP/γ-Al₂O₃ catalysts;the promoter probably affected the interaction between active components of WP/γ-Al₂O₃ catalysts and the support;Co and Ni improved the properties of WP/γ-Al₂O₃ catalysts for the hydrogenation reaction of C₅ petroleum resin.
