Problems solved by technology

However, U.S. Patent Nos. 5,439,867 and 6,056,871 have the limitation of poor flow regime and solid-state circulation due to the aspheric shape in the aspect of high wear loss
[0005] As mentioned above, the desulfurization adsorbents of the related art cannot meet the requirements necessary for the repeated use of the adsorbents in the adsorption regeneration cycle in the fluidized bed process, that is, higher sulfur adsorption capacity, spherical shape, fast reaction rate, appropriate average particle size and Particle size distribution and excellent abrasion resistance, and not suitable for mass production

Embodiment 1-3

[0062] An 8 kg solid powder sample having the composition shown in Table 1 was prepared.

[0063] The solid powder raw material prepared by 30 parts by weight (in distilled water) is added to distilled water in sequence, and anionic polycarboxylate dispersant and defoamer (non-polyester based polyester) are added at the same time with the composition shown in Table 1. ionic surfactant), using an emulsifying homogenizer to mix all components to prepare a slurry mixture.

[0064] The slurry was pulverized twice using a high energy bead mill to prepare a homogenized colloidal slurry.

[0065] Add a polyethylene glycol (PEG)-based organic binder to the colloidal slurry with the composition shown in Table 1, stir the slurry, age for 2 hours or more, and filter through a 120-mesh / 400-mesh sieve to remove foreign matter. The colloidal slurry from which foreign matter was removed was spray dried and the green body was placed in an oven at 120°C for 12 hours. After the furnace is he...

Abstract

The present invention relates to a desulfurizing agent composition and a preparation method thereof. The present invention uses a mixture of alumina and calcium silicate as a support, and an inorganic binder comprising one or more compounds selected from bentonite, boehmite or palygorskite, thereby providing a recyclable desulfurizing agent composition which can increase the utilization of active ingredients through uniform distribution of active ingredients and provide a wide specific surface area necessary for reaction, has the shape, particle size and distribution suitable for a hot gas, particularly fluidized bed or high speed fluidized bed desulfurization processes, and has improved abrasion resistance (strength), heat resistance and desulfurizing capability (sulfur absorption), and a preparation method thereof.

Description

technical field [0001] The invention relates to a desulfurization adsorbent capable of removing sulfur from sulfur-containing gas and a preparation method thereof. The desulfurization adsorbent of the present invention can be effectively used for desulfurization of hot gas in a fluidized bed process, which is obtained from sulfur-containing gas such as fuel gas or H in syngas produced by coal gasification in a high-temperature dry state. 2 S removes sulfur. Background technique [0002] Hot gas desulfurization is a technology used to remove sulfur from sulfur-containing gases such as fuel gases or such as coal or carbon-containing fuels such as industrial waste (such as petroleum coke, waste tires or solid H contained in synthesis gas from the gasification of solid fossil fuels such as waste (RDF) 2 S. Hot gas desulfurization technology is environmentally friendly because it does not require a waste water discharge process compared to wet-type desulfurization processes us...
