The clay treatment widely utilized to reduce unsaturated components in aromatic stream has a detrimental effect on catalyst lifetime. Due to the short lifetime of commercial clay, a huge number of studies have been carried out to address this problem over the last decade. This study aims to optimize the temperature for longer serviceability of clay by removal of unsaturated aliphatic components from aromatic streams through the adsorption and catalytic properties of clay. A novel process arrangement is introduced by scheduling the reuse of deactivated clay that is discarded after deactivation.

基于从芳烃中分离痕量烯烃过程中已知的毒物，优化温度并引入新的工艺安排以提高粘土的寿命

广泛用于减少芳烃流中不饱和组分的粘土处理对催化剂寿命有不利影响。由于商业粘土的寿命短，在过去十年中已经进行了大量的研究来解决这个问题。本研究旨在通过粘土的吸附和催化特性从芳烃流中去除不饱和脂肪族成分，从而优化粘土的更长使用寿命的温度。通过安排去活化后丢弃的去活化粘土的再利用，引入了一种新的工艺安排。
