preparation example Construction

[0035] The invention provides a deodorant with good safety, low cost, high purification degree and good desulfurization efficiency, and the preparation method is simple. It is used for adsorption and conversion of sulfur-containing substances in oxidative atmospheres such as air. The sulfur-containing substances are enriched on the deodorizer, and then they are catalyzed and converted into oxygen-containing sulfides to achieve the purpose of deodorization.

[0036] The polycarboxylic acid mentioned in the present invention refers to citric acid, oxalic acid or tartaric acid.

[0037] The CMC refers to sodium carboxymethyl cellulose, and its English name is Sodium Carboxymethyl Cellulose;

[0038] The PEG-1000 refers to polyethylene glycol 1000;

Abstract

The invention discloses a deodorant and a preparation method and application thereof. The deodorant is prepared from the following components: 2-55wt% of metallic oxide, 5-30wt% of alkaline earth compound, 10-60wt% of carrier, 1-10wt% of pore forming substance, 2-5wt% of extrusion assisting agent, and 2-10wt% of binder, the preparation method comprises the following steps of mixing all the materials, adding appropriate water, putting into a banded extruder for extruding into strip shape through disorderly pinching, drying at 50-200 DEG C, roasting at 150-450 DEG C, and obtaining the deodorant The deodorant can be used under the condition of 10-100 DEG C, 0.1-10Mpa, and 100-10000h<-1> of airspeed. The deodorant has large pore volume and specific surface area, and high sulfur capacity, one-way sulfur capacity of the deodorant is more than 30wt%, the removal efficiency of COS, mercaptan, thioether, dimethyl dithio is more than 90%, and benzene series and low carbon hydrocarbon substances are removed at the same time; the preparation method is simple, and has no pollution and low cost.

Description

technical field [0001] The invention relates to a deodorant, in particular to a deodorant and its preparation method and application. Background technique [0002] With the deepening of the industrialization process, sulfur-containing malodorous gases (such as H 2 S, COS, CS 2 , mercaptan, sulfide, dimethyl disulfide, etc.), benzene series and low-carbon hydrocarbon emissions, which seriously pollute the environment and endanger human health. At present, there are wet desulfurization, biological desulfurization, and IVP activated carbon adsorption desulfurization methods for industrial production of sulfur-containing odorous gases. However, wet desulfurization has large power consumption, high energy consumption, harsh control conditions, and secondary harmful substances. Disadvantages: Biological desulfurization needs to be combined with wet desulfurization, the reaction period is long, the reaction conditions are harsh, and it is not easy to operate; IVP activated carbon...
