    Abstract: The present invention relates to a process for selective removal of mercaptan from aviation turbine fuel (ATF) feed comprising: mixing aviation turbine fuel feed with hydrogen, at a pressure in range of 3 bar to 20 bar to obtain a reaction mixture, heating the reaction mixture at a temperature range of 150 °C to 350 °C to obtain a heated mixture, reacting the heated mixture with a hydrotreating catalyst in a rector to obtain a reactor effluent, stripping H2S gas from the reactor effluent to obtain a stripper bottom product, and removing moisture from the stripper bottom product to obtain aviation turbine fuel product having less than 10 ppm mercaptan. The process of present invention also improves properties such as colour, acidity etc of other products. The present invention further relates to an aviation turbine fuel product having less than 10 ppm mercaptan prepared by a process of the present invention. The process of present invention is flexible and can be employed for a grass root unit or retrofitting-existing unit.
