The liquid redox desulfurization using 2-nitroso-1-naphthol-4-sulfonic acid as redox catalyst has been studied by a stirred vessel, a laboratory apparatus and a pilot for 2, 000 Nm<SUP>3</SUP>/hr coal gas.<BR>The experimental results indicated that this redox catalyst has high activity and selec-tivity to thiosulfate. Particularly, on the pilot plant for 2, 000 Nm<SUP>3</SUP>/hr coal gas, 1 mol/m<SUP>3</SUP> of 2-nitroso-1-naphthol-4-sulfonic acid obtained the same desulfurization coefficiency as 2 mol/ma of ammonium 1, 4-naphthoquinone-2-sulfonate. Accordingly, for the liquid redox desulfuriza-tion where no sulfur is deposited in the solution, it is more excellent than the earlier organic catalysts such as ammonium 1, 4-naphthoquinone-2-sulfonate.
