PROCESS FOR PURIFICATION OF OLEFINIC FEEDSTOCKS USING AN ADSORBENT COMPRISING A 12 MR-TYPE ZEOLITE |
| 摘要 |
The invention relates to a process for purification of olefinic feedstocks using an adsorbent comprising a 12 MR-type zeolite, in which the zeolite content of said adsorbent is between 93% by weight and 100% by weight, and the binder content of said adsorbent is between 0 and 7% by weight, in which said zeolite contains silicon and an element T that is selected from the group that consists of aluminum, boron, gallium and iron, and in which the Si/T atomic ratio is less than 20. |

1. Process for purification of a hydrocarbon feedstock comprising olefins and at least one impurity comprising at least one heteoratom, in which a stage for bringing the feedstock into contact with an adsorbent comprising between 93% by weight and 99.8% by weight of zeolite and between 0.2 and 7% by weight of binder is carried out, with the zeolite being of the 12 MR type, in which said zeolite contains silicon and an element T selected from the group that consists of aluminum, boron, gallium and iron, and in which the Si/T atomic ratio of the zeolite is less than 20. |
