Abstract: Disclosed is a method for collecting sulfur from a synthetic gas. The method comprises the steps of performing desulfurization by which the synthetic gas including sulfur components is fed so that sulfur compounds are attached on a catalyst that is fixed to each of multiple desulfurization/reproduction reactors and discharging a purified synthetic gas from which the sulfur components are removed; performing reproduction by which oxygen is supplied so that the sulfur compounds attached on the catalyst of the desulfurization/reproduction reactors are oxidized and discharging sulfur dioxide that is converted from the sulfur compounds by means of the oxidation of the catalyst; supplying the sulfur compounds that are oxidized through the reproduction to a sulfur collecting reactor; separating sulfur as a solid by supplying a reducing agent so that the sulfur dioxide is converted into sulfur through reduction in the sulfur collecting reactor; and discharging the separated elemental sulfur in order to be collected.

Abstract: A method for preparing a Cu-Zn-Al based hybrid catalyst, the Cu-Zn-Al based hybrid catalyst prepared by the method, and a method for directly synthesizing dimethylether from syngas using the Cu-Zn-Al based hybrid catalyst are provided, wherein the Cu-Zn-Al based hybrid catalyst synthesizes dimethylether at high purity and high yield from syngas by maintaining excellent activity compared to existing hybrid catalysts. A method for preparing a Cu-Zn-Al based hybrid catalyst comprises the steps of: (1) dissolving copper(II) acetate(Cu(C2H3O2)2) and zinc acetate(Zn(C2H3O2)2) into water to form an aqueous Cu-Zn precursor solution; (2) adding an ammonium carbonate((NH4)2CO3) precipitant into the aqueous Cu-Zn precursor solution of the step(1) at a rate of 3 to 15 ml/min to coprecipitate Cu and Zn; and (3) filtering, cleaning, drying, and firing a sediment produced in the step(2) to obtain a Cu-Zn based oxide, and mixing the Cu-Zn based oxide with gamma-alumina(gamma-Al2O3). The copper(II) acetate and zinc acetate are used in the amount satisfying a Cu to Zn mole ratio of 5 to 9:1 to 5 in the step(1). The ammonium carbonate precipitant is added into the aqueous Cu-Zn precursor solution at a rate of 4.5 to 10 ml/min in the step(2). The ammonium carbonate precipitant is added in the form of an aqueous solution with a concentration of 1 to 3 M in the step(2). Further, a mixing ratio of the Cu-Zn based oxide and the gamma-alumina is 4 to 6:6 to 4.
