| 1 | Influence of Steam Treating on Deethylating Type Isomerization Catalyst显示文摘This article mainly worked on methods to reduce side reactions of the de-ethylating type catalyst for xylene isomerization. In laboratory the de-ethylating type catalyst for xylene isomerization was subjected to steam treatment at different temperatures and durations to achieve dealumination of the ZSM-5 zeolite to some extent, which could affect the change in Bronsted acid content to decrease xylene loss along with reduction of side reactions. Test results showed that the degree for reducing side reactions by steam treatment depended upon two important parameters-treating temperature and duration. The optimal condition required treating the catalyst at 500℃ for 8 hours. | Cao Ku Gu Haohui Liang ZhanQiao Ruan Chi Liu Zhongxun Gui Shoux | 2005 | China Petroleum Processing & Petrochemical Technology2005，7，2： | 1 |
