Abstract	Application of nano molybdenum oxide catalyst in gas sweetening is studied, in this work. Experiments are held to evaluate the operating and geometrical parameters in the adsorption process. The quality of process is defined as the ratio of final concentration of H2S on the initial concentration of H2S. Different values of temperatures, different values of nano particle diameter and also, various values of pressure are emerged on the catalytic bed with 3 cm height and 8 cm diameter. Desulphurization is a set of technologies used to remove sulphur dioxide ( SO2 ) sour fuel and from the emissions of other sulphur oxide emitting processes. Methods of removing sulfur dioxide from sour gas and sour oil and furnace exhaust gases have been studied for over 150 years. Early ideas for sour gas, oil and flue gas desulfurization were established in England around 1850 [1]. With the construction of large-scale power plants in England in the 1920s, the problems associated with large volumes of SO2 from a single site began to concern the public. The SO2 emissions problem did not receive much attention until 1929, when the House of Lords upheld the claim of a landowner against the Barton Electricity Works of the Manchester Corporation for damages to his land resulting from SO2 emissions. Shortly thereafter, a press campaign was launched against the erection of power plants within the confines of London [1]. This outcry led to the imposition of SO2 controls on all such power plants. The first major desulfurization unit at a utility was installed in 1931 at Battersea Power Station, owned by London Power Company. In 1935, a desulfurization system similar to that installed at Battersea went into service at Swansea Power Station [2]. The third major desulfurization system was installed in 1938 at Fulham Power Station. These three early large-scale desulfurization installations were abandoned during World War II. Large-scale desulfurization units did not reappear at utilities until the 1970s, where most of the installations occurred in the United States and Japan. Desulphurisation of in-situ gas and crude oil is an important process used in a petroleum refinery to reduce the sulphur concentration and production of fuel products such as gasoline, jet fuel, kerosene, diesel and heating oil [3]. So, the resulting fuels meet environmental protection standards. The challenge of fulfilling the world’s growing transportation energy needs is no longer a simple issue of producing enough liquid hydrocarbon fuels [3]. This challenge is instead accentuated by a complex interplay of environmental and operational issues. Environmental issues include societal demands that liquid hydrocarbon fuels be clean and less polluting [4]. The emergence of new refining processes and the increasing use of new forms of energy production, e.g., fuel cells, exemplify operational issues. Together, these trends are driving the need for deep desulfurization of diesel and jet fuels. This paper focuses on the configuration of synthesized molybdenum nano particles which are affected on the sweetening of sour gas.
