In this paper, aluminum oxide nano particles are synthesized and are contacted with a flow of sour LPG. The synthesized nano particles are characterized by SEM and TEM. The process performance of mercaptan removal from LPG on zinc oxide nano particles is illustrated by the ratio of outlet concentration per feed concentration. The effects of operating conditions such as operating temperature and pressure, the amount of mercaptan concentration in feed stream, size of nano catalyst, the bed diameter and also, height of the bed are investigated in this paper. This work studies the adsorption of mercaptan from liquefied petroleum gas with an emphasis on the influence of the operating and geometric parameters on process efficiency. The experimental results show the changes of height from 6 cm to 7 cm decrease the amount of quality index from 0.032 to 0.027. But the variation from 7 to 9 doesn't show any changes in the amount of C/C0 as quality index.
