Modified activated carbon desulfurizing/dephosphorizing agent and preparation method thereof

Abstract

The invention relates to a modified activated carbon desulfurizing / dephosphorizing agent which is prepared from the following raw materials in parts by weight: 120-130 parts of activated carbon, 7-9 parts of cuprous chloride, 10-15 parts of sunflower seed husk, 10-15 parts of castor husk, 7-10 parts of attapulgite clay, 6-9 parts of bauxite, 7-10 parts of calcium oxide, 7-10 parts of sodium carbonate, 5-8 parts of ferrous sulfate, 8-11 parts of maleic acid, 2-4 parts of ascorbic acid, 4-5 parts of modified kieselguhr and right amount of water. The sunflower seed husk and castor husk are subjected to high temperature carbonization to form a structure with higher specific area, higher micropore volume and larger pore size; the calcium oxide and other metal oxides can implement high-efficiency desulfurization; the added ferrous sulfate can efficiently remove phosphates; the cuprous chloride can removel chlorine; the attapulgite clay and other natural stone powders can implement microbial resistance, deodorization, moisture absorption, catalysis and cohesiveness, so that the activated carbon can not be easily disintegrated; and the activated carbon is suitable for removing sulfur, phosphorus, chlorine and other metallic ions, and has excellent prospects.

Description

technical field [0001] The invention relates to the field of modified functional materials, in particular to a modified activated carbon desulfurization agent and a preparation method thereof. Background technique [0002] At present, adsorbents are often used to remove toxins, mainly silica gel, activated alumina, activated carbon, molecular sieves, etc., and there are also adsorption materials developed for the selective adsorption of certain components. However, most of these adsorbents have limited adsorption capacity, and different adsorbents need to be studied according to different requirements to play the best role. At the same time, look for new raw materials to enhance the adsorption effect and save costs. Contents of the invention [0003] The object of the present invention is to provide a modified activated carbon desulfurization agent and a preparation method thereof. [0004] Technical scheme of the present invention is as follows: [0005] A modified act...
