Accession number: 20134416914282 Title: Application of phosphorus modified ZSM-5/aluminophosphates composite zeolite in methanol to propylene reaction Authors: Wang, Lin1, 2 Email author wanglin022506@163.com; Wang, Zheng1 Email author wzheng@nxu.edu.cn; An, Liangcheng1; Yong, Xiaojing2; Luo, Chuntao2 Author affiliation: 1 Key Laboratory of Energy Resources and Chemical Engineering of Ningxia, Ministry-Province Co-cultivated State Key Laboratory Base of Natural Gas Conversion, Yinchuan 750021, China 2 Coal Chemical Company, Shenhua Ningxia Coal Group, Yinchuan 750411, China Corresponding author: Wang, Z. (wzheng@nxu.edu.cn) Source title: Shiyou Xuebao, Shiyou Jiagong/Acta Petrolei Sinica (Petroleum Processing Section) Abbreviated source title: Shiyou Xuebao Shiyou Jiagong Volume: 29 Issue: 4 Issue date: August 2013 Publication year: 2013 Pages: 597-604 Language: Chinese ISSN: 10018719 CODEN: SXSHEY Document type: Journal article (JA) Publisher: Science Press, 18,Shuangqing Street,Haidian, Beijing, 100085, China Abstract: P modified ZSM-5/aluminophosphates composite zeolite (wP-ZSM-5/AlPO4-m) was obtained by NH4H2PO4 modification of ZSM-5/AlPO4-m and characterized by XRD, N2 adsorption-desorption, NH3-TPD, FT-IR and so on. The effects of P loaded amount in wP-ZSM-5/AlPO4-m and the reaction conditions, reaction temperature and space velocity, on methanol conversion and product selectivity of MTP were investigated. It was confirmed that the surface area, acid strength and acid amount of wP-ZSM-5/AlPO4-m were effectively regulated by P modification, and the maximum ratio of B acid and L acid reached 3.03 in 3%P-ZSM-5/AlPO4-m, which had the best catalytic activity and stability at the reaction temperature of 500°C and MHSV of 1 h-1. The conversion rate of methanol, selectivity of propylene, molar ratio of propylene and ethylene remained around 100%, 50% and 5, respectively, when the reaction continued for 73 h.
