Sulphur in hydrocarbon cuts has different forms such as element sulphur (S) (H2S), COS, CS2, RSH (mercaptans), thiophene, and other sulphur compounds. Meanwhile, nano catalysts are adapted in this paper to vanish mercaptan as the side element, corrosive and pyrophoric contaminant. For this purpose, DMD process has been developed as a de-mercaptanization process providing the possibility of de-mercaptanization of different hydrocarbon cuts even crude oil as a feed. Zinc oxide nano particles are used as catalytic bed to remove the mercaptan content of liquefied petroleum gas. So, the effect of initial concentration of mercaptan in inlet liquefied petroleum gas to the catalytic bed is evaluated. The mercaptan removal from liquefied petroleum gas is defined as C/C⁰. Experimental results show the efficiency of zinc oxide nano particles are decreased with increasing the mercaptan content of inlet liquefied petroleum gas.
