Effects of controlled TEOS deposition and phosphorous doping on ethylene to propylene reaction over SSZ-13 catalyst |
| 초록 |
Propylene is very important raw material for polypropylene, propylene oxide and acrylonitrile, and usually produced from naphtha cracking or dehydrogenation of propane. The direct conversion of ethylene to propylene (ETP) reaction attracts much attention recently because the supply of propylene might be deficient in near future considering the rapid increasing ethylene supply from ethane cracker and shale gas. SSZ-13 catalyst for ETP reaction is very interesting considering the high propylene yield and relatively good stability. In this study, ETP reaction was carried out over SSZ-13 and modified SSZ-13 catalysts at 330℃, 1 atm. SSZ-13 catalyst was modified by phosphorus doping and a chemical liquid deposition (CLD) technique using TEOS. It was found that the order of propylene yield was P treatment ＞ CLD technique using TEOS ＞ untreated one. This enhance activity by a phosphorus doping treatment would be caused due to lowering a strong acidity in TPD result. |
