Abstract

The invention discloses a method for preparing a desulfurization adsorbent from industrial solid wastes. The method comprises the following steps: adding a solution a into a reaction kettle, adding aNi(NO3)2 solution, performing stirring, adding an adsorbent carrier into the reaction kettle, heating the reaction kettle, and performing a reaction; dropwise adding a sodium bicarbonate solution intothe reaction kettle by a constant pressure burette, increasing the rotating speed, continuing stirring, and stopping the stirring to obtain a mixed solution a; weighing excess anhydrous Na2CO3, pouring the anhydrous Na2CO3 into the mixed solution a, dropwise adding a solution b into the reaction kettle by the constant pressure burette, continuing stirring after the dropwise addition is completed,and stopping the stirring to obtain a mixed solution b; performing suction filtration on the mixed solution b, and washing a filter cake with deionized water in the suction filtration process until the obtained filtrate is neutral; and taking the filter cake, drying and calcining the filter cake, and cooling the filter cake to room temperature to obtain the desulfurization adsorbent. The industrial solid wastes used in the invention enhance the strength and the wear resistance of the desulfurization adsorbent, and makes the desulfurization adsorbent have a large specific surface area, have good selectivity to sulfur and have a good adsorption effect.

Description

technical field [0001] The invention belongs to the technical field of adsorption materials, and in particular relates to a method for preparing a desulfurization adsorbent by utilizing industrial solid waste, and an application of the prepared desulfurization adsorbent. Background technique [0002] As people pay more and more attention to environmental protection, environmental regulations are becoming stricter, and reducing the sulfur content of gasoline and diesel is considered to be one of the most important measures to improve air quality, because sulfur in fuel will affect the performance of automotive catalytic converters produce adverse effects. Sulfur oxides present in automobile engine exhaust can inhibit and irreversibly poison precious metal catalysts in converters. Exhaust gases from inefficient or poisoned converters contain unburned non-methane hydrocarbons and oxides of nitrogen and carbon monoxide, which are catalyzed by sunlight to form photochemical smog...
