NOVELTY - The process comprises feeding hydrogen and a hydrocarbon stream comprising hydrogen sulfide and mercaptans to a high temperature low pressure reactor comprising a hydrodesulfurization catalyst, contacting the hydrocarbons and mercaptans in the presence of hydrodesulfurization catalyst at a temperature of 500-700 degrees F and a pressure of less than 320 psig to form a hydrocarbon stream having a reduced mercaptan content, and feeding hydrocarbon stream comprising organic sulfur compounds to a catalytic distillation reactor system having reaction zones (26) comprising hydrodesulfurization catalyst.    USE - The process is useful for reducing the sulfur content of a hydrocarbon stream.    ADVANTAGE - The process is capable of economically and easily minimizing or controlling the formation of recombinant mercaptans without the need for stripping the gasoline of hydrogen sulfide thus effectively reducing organic sulfur content in the hydrocarbon stream and preventing corrosion in automobiles.    DETAILED DESCRIPTION - The process comprises feeding hydrogen and a hydrocarbon stream comprising hydrogen sulfide and mercaptans to a high temperature low pressure reactor comprising a hydrodesulfurization catalyst, contacting the hydrocarbons and mercaptans in the presence of the hydrodesulfurization catalyst at a temperature of 500-700 degrees F and a pressure of less than 320 psig to form a hydrocarbon stream having a reduced mercaptan content, feeding a hydrocarbon stream comprising organic sulfur compounds to a catalytic distillation reactor system having reaction zones (26) comprising hydrodesulfurization catalyst, feeding hydrogen to the catalytic distillation reactor system, heating the overheads fraction to a temperature of 500-700 degrees F, feeding the heated overheads fraction and hydrogen to the high temperature low pressure reactor comprising hydrodesulfurization catalyst to form hydrogen sulfide and a reactor effluent of reduced mercaptan content, separating the reactor effluent, hydrogen sulfide and any unreacted hydrogen to form light hydrocarbon fraction and a fraction comprising hydrogen sulfide and hydrogen, recycling a portion of the light hydrocarbon fraction as reflux to the catalytic distillation reactor system, decreasing a pressure of the overheads fraction, separating a portion of the hydrogen sulfide from the fraction comprising hydrogen and hydrogen sulfide, recycling a portion of the hydrogen to the distillation column reactor system (10) and the high temperature low pressure reactor, feeding a portion of the bottoms fraction to the high temperature low pressure reactor, combining the bottoms fraction and the light hydrocarbon fraction, fractionating the combined fractions to form a fraction comprising 5 carbon and lighter hydrocarbons and a fraction comprising 6 carbon and heavier hydrocarbons, and feeding a portion of the 6 carbon and heavier hydrocarbons to the high temperature low pressure reactor. The hydrogen sulfide is present in the hydrocarbon stream at a partial pressure of 0.05-5 psi. The hydrogen is fed to the high temperature low pressure reactor at a rate of less than 2500 scf/barrel. In the catalytic distillation reactor system, the hydrocarbon stream is fractionated into a heavy fraction and a light fraction, the hydrogen and the light fraction is contacted in the reaction zones to form hydrogen sulfide and a light fraction of reduced organic sulfur content, the light fraction, the hydrogen sulfide and any unreacted hydrogen is recovered as an overheads fraction, and the heavy fraction is recovered as bottoms fraction. A pressure in the high temperature low pressure reactor is 25-320 psig. The bottoms fraction is contacted with hydrogen in the presence of hydrodesulfurization catalyst to form heavy fraction of reduced organic sulfur content. The heavy fraction is contacted with hydrogen in the reaction zone of the catalytic distillation column reactor to form hydrogen sulfide and the heavy fraction of reduced organic sulfur content. The hydrogen stream comprises a full range cracked naphtha. The step of feeding the hydrogen comprises feeding the hydrogen to a location below each of the reaction zones in the catalytic distillation reactor system. The hydrodesulfurization catalyst in the high temperature low pressure reactor comprises nickel catalysts with very low molybdenum promotion, nickel catalysts with no promoters, molybdenum catalysts with very low copper promotion, and molybdenum catalysts with no promoters.
