摘要： A process for the removal and conversion into sulfur of hydrogen sulfide in a gaseous or liquid material which comprises essentially treating the said material with an oxidative lignin prepared by treating lignins with oxidizing agents, nitrating agents and/or demethylating agents and, if desired, introducing hydrophilic groups into the resultant product. The lignins include protolignin, isolated lignins and other denatured lignins. The process is advantageous essentially in that hydrogen sulfide can be removed economically and converted completely into sulfur, and that the desulfurization agents, i.e. the oxidative lignins, are non-toxic and non-corrosive.
