NOVELTY - Preparing sorbent material, comprises: adding a solution or suspension consisting of at least one iron salt, optionally at least one salt of element comprising copper, nickel, cobalt, manganese, zinc or aluminum and optionally insoluble support material to solution comprising alkali metal carbonate to form suspension comprising precipitated iron compounds until pH of suspension is less than or equal to 5; adding alkaline compound to the suspension to raise its pH to greater than or equal to 7; separating precipitated iron compounds at pH of greater than or equal to 7; washing the separated precipitated iron compounds; and drying.    USE - The method is useful for preparing sorbent material which is useful in process fluid, where the process fluid is natural stream comprising methane and optionally carbon dioxide and the natural gas stream has no added water (all claimed) and for removing sulfur compounds (e.g. natural gas liquid, naphtha, or a synthesis gas, or organic compounds such as alcohols, esters, or chlorinated hydrocarbons or other gases such as carbon dioxide, hydrogen, nitrogen, or helium) from process fluids.    ADVANTAGE - The method provides process fluids that need not have added water (vapor or liquid) thus less expense for removing sulfur compounds and often does not requires separation of water vapor from the desulfurized gas.    DETAILED DESCRIPTION - Preparing sorbent material, comprises adding solution or suspension consisting of iron salt, optionally at least one salt of element comprising copper, nickel, cobalt, manganese, zinc or aluminum and optionally an insoluble support material, to a solution comprising an alkali metal carbonate to form a suspension comprising precipitated iron compounds until the pH of the suspension is less than or equal to 5; adding alkaline compound to the suspension to raise its pH to greater than or equal to 7; separating the precipitated iron compounds from the suspension at a pH of greater than or equal to 7; washing the separated precipitated iron compounds to remove residual alkali metal salts; and drying the washed precipitate at less than or equal to 350 degrees C.
