芳族物的烷基化方法;AROMATICS ALKYLATION PROCESS

摘要

在一种芳族物的烷基化方法中，将包含可烷基化芳族烃、至少150重量ppm之水及至少一种有机氮杂质的芳族烃原料供应至从该芳族烃原料去除水之脱水区，以提供水含量不超过20重量ppm之经脱水芳族原料。然后在包括低于130℃之温度的条件下使该经脱水芳族原料与黏土吸附剂接触，以使该吸附剂去除至少部分包含在原料中之该有机氮杂质，且产生经处理芳族原料。然后将该经处理芳族原料供应至烷基化反应区及/或转烷化反应区。 In an aromatics alkylation process, an aromatic hydrocarbon feedstock comprising an alkylatable aromatic hydrocarbon, at least 150 ppm by weight water and at least one organic nitrogen impurity is supplied to a dehydration zone where water is removed from the aromatic hydrocarbon feedstock to provide a dehydrated aromatic feedstock having a water content of no more than 20 ppm by weight. The dehydrated aromatic feedstock is then contacted with a clay adsorbent under conditions including a temperature less than 130℃
