Abstract
A modified activated carbon adsorption desulfurization agent is prepared from the following raw materials: by weight, 100-120 parts of coconut shell activated carbon, 1-2 parts of ammonium persulfate, 1-2 parts of copper oxide, 1-2 parts of lanthanum oxide, 1-2 parts of chromium oxide, 12-14 parts of corn cob, 1-2 parts of agar, 4-5 parts of glycerin, 8-10 parts of modified attapulgite and a proper amount of water. The modified activated carbon adsorption desulfurization agent containing lanthanum, chromium, copper and multiple metal oxides can more thoroughly and rapidly oxidize sulfides; the modified activated carbon adsorption desulfurization agent processed by spray drying has higher activity and stronger adsorption ability; and due to the addition of the corn cob, the modified activated carbon adsorption desulfurization agent has more spaces and can absorb more sulfides.
Description
Technical field
The present invention relates to a kind of method of modifying of nonmetallic ore, relate in particular to a kind of modified activated carbon adsorption desulfurizing agent and preparation method thereof.
Background technology
Along with scientific and technological development, the progressively construction of modernization industry, various chemicals are exploited, and have brought facility to people's life, simultaneously because chemicals has produced environment and the harmful material of human body, the problem that has also become people to have to face.
Current airborne pollutant is mainly the toxic and harmful produced in the gas that produces of industrial fuel burning, vehicle exhaust, production.It is mainly to contain a large amount of noxious materials in the sewage of industrial production discharge that water pollutes, and also has the sewage in people's life to produce a lot of harmful substances.Also have and many times need to remove toxin in people life, such as air conditioning filter has a lot of bacteriums, toxin on the net, newly-decorated has the harmful substance such as formaldehyde, all needs to remove toxin.All remove at present toxin and often use adsorbent, mainly contain silica gel, activated alumina, active carbon, molecular sieve etc., the sorbing material of developing for certain compositional selecting absorption in addition in addition.But the most adsorption capacity of these adsorbents is limited, need to study different adsorbents for different requirements, bring into play best effect.Simultaneously, find new raw material, to strengthen adsorption effect, cost-saving.
