Problems solved by technology

These manganese-based desulfurizers must be reduced before use. The reduction process is laborious and time-consuming, which not only increases the operating time of the device and increases the cost, but also easily causes accidents such as overheating of the desulfurizer, deactivation of the desulfurizer, and damage to the reactor. , at the same time, the use is limited in the absence of reducing gas

Embodiment 1

[0039] The content of iron element in the material for desulfurization is 0.1 mg / g, the content of copper element is 0.1 mg / g, and the average particle size of the material for desulfurization is 2.0 mm.

Embodiment 2-12

[0041] Table 1

Embodiment 13-28

The elements of the first type supported in this part of the embodiments individually include one of iron, copper or titanium.

[0043] Referring to Example 1, according to the specific element formulation to be loaded, any acceptable form of compound is selected as a precursor to prepare a corresponding first impregnating liquid.

[0044] For example, when loading 0.1 mg / g of iron, weigh 43.2 mg of ferric nitrate and dissolve it in 100 ml of water to obtain the first immersion solution;

When 0.1 mg / g copper element is loaded, 29.6 mg of copper nitrate is weighed and dissolved in 100 ml of water to obtain another first dipping solution; and so on.

[0045] The content of the loaded elements in the materials for desulfurization prepared in each example is shown in the following table.

Abstract

The invention provides a substance for desulfurization as well as a preparation method and application thereof. The substance for desulfurization is composed of an adsorption carrier and a loading element, the load elements comprise a first type of elements; the first element is at least one of iron, titanium and copper. The substance for desulfurization is particularly suitable for industrial desulfurization of coke oven gas and blast furnace gas, and the desulfurization efficiency is high. In addition, the substance for desulfurization is long in service life, and the industrial use cost can be reduced. The preparation method of the substance for desulfurization is simple in process, the type and content of the loaded elements are convenient to adjust, large step flow change is not needed, the variety of products is convenient to enrich, and the income is increased.

Description

technical field [0001] The present invention relates to the field of industrial desulfurization, and more particularly, to a substance for desulfurization, a preparation method and application thereof. Background technique [0002] Coke oven gas is a combustible gas produced when coke and tar products are produced after the coking coal prepared from several bituminous coals is subjected to high temperature dry distillation in a coke oven. It is a by-product of the coking industry. If the coke oven gas is directly discharged into the atmosphere without utilization, it will not only waste scarce energy, but also cause serious pollution to the environment. Due to the complex composition of coke oven gas and high sulfide content, it is easy to poison the subsequent reforming catalyst and synthesis catalyst, affecting the normal production operation of production. Therefore, before coke oven gas is used for downstream deep processing, it is necessary to remove sulfides, so as to...
