Abstract: Nano catalytic sulphur removal process is surveyed in this research, experimentally. Qualification of sulphur removal from liquefied natural gas process is investigated due to catalytic bed geometries which contains nano ferrite oxide and operation conditions. The purpose of experiments is finding the conditions which lead to the lowest amount of sulphur content in the out stream. Fraction of sulphur content in the outlet to the amount of sulphur in the inlet is considered as the operation criteria in this work. The effects of operating conditions such as operating temperature and pressure, the amount of sulphur concentration in feed stream, size of nano catalyst, the bed diameter and bed height are investigated. The different correlations with high confidence factor are introduced in this paper. Results show the diameter changes from 1-2 cm and the ratio of C/C0 changes from 0.05-0.03.
