Problems solved by technology

[0002] Natural gas contains organic sulfide impurities, such as sulfide, mercaptan, hydrogen sulfide, etc. These organic sulfides will cause corrosion of gas transmission pipelines, and also cause catalyst poisoning, which will reduce the quality of natural gas, so they must be removed
[0003] Among organic sulfides, the removal of organic sulfides is more difficult. The traditional method of organic sulfur removal is catalytic hydrodesulfurization, but this will consume a large amount of hydrogen, resulting in increased gas transmission costs; while the existing normal temperature Adsorption desulfurization technology also has the disadvantages of low sulfur capacity, difficulty in regeneration, and high desulfurization cost

Abstract

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.

Description

technical field [0001] The invention relates to a preparation method of a porous composite desulfurizer used for removing organic sulfides, and belongs to the technical field of preparation and application of composite desulfurizers. Background technique [0002] Natural gas contains organic sulfide impurities, such as sulfides, mercaptans, hydrogen sulfide, etc. These organic sulfides will cause corrosion of gas pipelines, catalyst poisoning, and degrade the quality of natural gas, so they must be removed. [0003] Among organic sulfides, the removal of organic sulfides is more difficult. The traditional method of organic sulfur removal is catalytic hydrodesulfurization, but this will consume a large amount of hydrogen, resulting in increased gas transmission costs; while the existing normal temperature Adsorption desulfurization technology also has the disadvantages of low sulfur capacity, difficulty in regeneration, and high desulfurization cost.
