Pd/HZSM-5涂层催化剂及正十二烷裂解

摘要采用涂覆法在不锈钢反应管内壁制备了Pd/HZSM-5涂层催化剂,并研究正十二烷裂解过程。采用SEM和XPS研究了涂层催化剂的表面结构,形态和组成,结果表明涂层表面平整,厚度大约10μm,Pd主要以0价态存在。600℃,4 MPa条件下正十二烷裂解热沉和产物分布结果表明,HZSM-5催化裂解热沉较热裂解热沉明显提高,负载Pd后,热沉进一步提高16.9%。

Abstract： A method for the preparation of Pd-supported HZSM-5 zeolite film was described.The cracking of jet fuel model compound of n-dodecane in Pd/HZSM-5 catalyst-coated tube was studied.The Pd/HZSM-5 film was characterized by SEM and XPS.It was shown that,the surface was approximately flat and the thickness of the zeolite-coating layer was about 10 μm.And Pd existed as metallic state.The heat sink and the decomposition under 4 MPa at(600 ℃,) showed that the heat sink could be enhanced due to the existence of zeolite HZSM-5,and Pd/HZSM-5 film can increase the heat sink by 16.9%.
