The invention relates to a method for preparing a porous compound desulfurizer for removing an organic sulfide. Against the conditions that organic sulfur in natural gas and particularly sulfur ether are difficult to remove and the desulfurizer is difficult to regenerate after being used, a metal organic frame compound is compounded with activated carbon; through preparation of activated carbon mixed liquid, reaction kettle hydro-thermal synthesis, soaking, suction filtration, washing and vacuum freezing drying, the porous compound desulfurizer is prepared, the porous compound desulfurizer is black blue crystal, the crystal is in an octahedron shape, the crystal particle size is smaller than or equal to 17 [mu]m, the crystal particle is in a porous shape, the pore diameter size is smaller than or equal to 0.7 nm, the product purity is 99.6%, the product can be used for removing the organic sulfide in natural gas and have a very good sulfur ether removing effect, the desulfurizer is reproducible after adsorbing sulfur ether, and the use cost is reduced. The preparation method is advanced in process, data is precise, detailed and accurate, the product is good in purity and high in precision, and the method is an advanced method for preparing the porous compound desulfurizer for removing the organic sulfur and particularly sulfur ether.
