Abstract

The invention relates to a preparation method of an iron oxide desulfurizer having controllable textural properties. The iron oxide desulfurizer comprises steel-making red mud as a raw material, bentonite as a binder, styrene as a pore forming agent, potassium persulfate as an initiator, sodium bicarbonate and sodium hydroxide as a pH regulating agent, and deionized water as a solvent. The preparation method comprises the following steps: firstly preparing a polystyrene microsphere emulsion as the pore forming agent, then mixing the polystyrene microsphere emulsion with steel-making red mud, bentonite, and calcium stearate, kneading and extruding into strips, drying and carrying out high temperature sintering on the strips to obtain the iron oxide desulfurizer having controllable texturalproperties. The iron oxide desulfurizer having controllable textural properties is brownish red. The use of the steel-making red mud in the method is a recycling of waste, thus the cost is low. The preparation method has the advantages of short process flow, few devices used herein, detailed and accurate data, high product purity, high desulfuration efficiency which can reach 98 %, short regeneration time of the desulfurizer, and good regeneration effect. The preparation method is an ideal method for preparing the desulfurizer through recycling wastes.

Description

technical field [0001] The invention relates to a preparation method of an iron oxide desulfurizer with controllable texture properties, belonging to the technical field of preparation and application of high-temperature gas desulfurizers. Background technique [0002] Integrated coal gasification combined cycle power generation technology, referred to as IGCC, is a promising clean coal utilization technology in the 21st century. Among them, high-temperature gas desulfurization is the key to IGCC technology, but the instability of gas desulfurizers makes this technology unrealized so far. industrialization. [0003] The texture parameters of the gas desulfurizer have a great influence on the performance, and the pore volume of the catalyst directly affects the stability of the catalyst. It is found that when the pores are within a certain range, the desulfurization effect of the desulfurizer will increase with the increase of the specific surface area ; but when the specifi...
