Abstract
The invention relates to a modified activated carbon hydrogen sulfide adsorbent which is prepared from the following raw materials in parts by weight: 100-120 parts of activated carbon, 12-14 parts of copper sulfate, 20-23 parts of high-alumina bauxite, 4-5 parts of magnesium oxide, 5-6 parts of calcium oxide, 6-8 parts of sodium carbonate, 8-10 parts of modified attapulgite and a right amount of water. According to the invention, the activated carbon is modified by using copper sulfate, high-alumina bauxite, magnesium oxide, calcium oxide and sodium carbonate, so that the removal efficiency of hydrogen sulfide is increased; the reaction activity of the activated carbon is improved by processes such as calcination and spray drying, thereby being favorable to the removal of sulfides contained in low-concentration fume. The modified activated carbon hydrogen sulfide adsorbent is simple in process and easily available in raw materials, and can realize industrial production.
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 hydrogen sulfide adsorbent 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, simultaneously because chemicals has produced environment and the harmful material of human body, the problem that has also become people to have to face to people's life.
Current airborne pollutant is mainly the toxic and harmful producing 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.In people's life, also have and many times need to remove toxin, such as air conditioning filter has a lot of bacteriums, toxin on the net, newly-decorated has the harmful substances 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., also have in addition for certain compositional selecting absorption and the sorbing material of development.But the most adsorption capacity of these adsorbents is limited, need to study different adsorbents for different requirements, bring into play best effect.Meanwhile, find new raw material, to strengthen adsorption effect, cost-saving.
