摘要： The present subject matter relates to the development of active catalyst composite based on supported transition metal oxides, especially, Cu, Co that are effective in the removal sulfides in the diluted spent caustic. The process for the reduction of sulfides in spent caustic comprises of reacting various organic and inorganic sulfides with molecular oxygen in the presence of active catalyst at various reaction temperatures ranging ambient to 200° C. and pressures between atmospheric pressure to 60 bars. The process also relates to complete scheme for the removal of sulfides in spent caustic.
