Alumina Active.. Intro

Alumina  Introduction

Activated Alumina ball having a lot of white pellets capillary channel , there are many pores channel , these channels have a higher activity on the surface , to the gas , vapor, liquid water has a selective adsorption ability . Under certain conditions, drying depth of up to -70 below the dew point, saturation at 175 -400 heating in addition to water and resurrection , can many times, also from the contaminated oxygen, hydrogen, sulfur dioxide adsorption lubricants and other oil steam , may make the catalyst or carrier. Widely used in petrochemical , oil refining , electronics, ethylene, propylene, air drying device , the country has a lot of hydrogen peroxide plant , fertilizer plant, oxygen plant and petrochemical refining units , and achieved good results.
Activated alumina ball of the adsorbed substances to determine the strength of the polarity of water , oxide, acetic acid, alkali and other strong affinity is a micro water depth of desiccant is adsorbed polar molecules adsorbed agent.
Features
This product has high strength, low wear, flooding the same soft, not inflated, not powder, not crack. It can be widely used in petroleum cracking gas , ethylene propylene depth of drying and hydrogen gas , air separation , instrument air drying machine drying , hydrogen peroxide , fluoride treatment can also remove sulfur in the exhaust gas of hydrogen, sulfur dioxide, hydrogen fluoride , hydrocarbons , etc. pollutants , particularly adapted to fluoridated water fluoride treatment .
Alumina Product Use
In the petrochemical, fertilizer industry, widely used as catalysts, catalyst supports.Activated Alumina and adsorption characteristics, and thus used as a gas and liquid desiccant, adsorbent for gas purification, drinking water fluoride removal agent, industrial effluent color and odor eliminating agents.
Household fluoride cylinder with supporting the use of drinking water is an ideal family fluoride devices. The fluoride removal filter with water plants can also be fluoride device or devices supporting the use of fluoride for industrial use. Household apparatus fluoride fluoride activation of filter: Configuration aluminum sulfate solution (3 liters of water, 0.3kg of solid aluminum sulfate), aluminum fluoride removal filter into the above solution for 5-10 hours discarded immersion (dipping in an appropriate mixing), and then washed with water and then 3-5 times, each about 2 liters of water, or by adjusting PH Regeneration, PH value of control in 7.5. Activated alumina fluoride removal filter can be used continuously for 6-8 years, when the surface appears brown when the effect of fluoride removal significantly reduced, the Department of impurities in the water due to contamination, so it is best to use three percent every six months once dilute hydrochloric acid, and its the same operation and the regeneration method.

alumina purposes

High performance of activated alumina in monolithic refractories ingredients can bring the following benefits: enhance body density, mobility, strength, improve the secondary mullite generation, reduce the water content and porosity. In addition, the activated alumina also can do desiccant, water absorbing capacity big, fast drying speed. Activated alumina belong to the category of chemical alumina, it is mainly used for fluoride agent, adsorbent, water purifier, catalyst and catalyst carrier. Polyaluminium chloride USES: polyaluminium chloride is mainly used for purification of drinking water and industrial wastewater, the quality of the special processing, such as smelting, printing and dyeing, papermaking wastewater, oily wastewater and the sewage, containing radioactive material, containing Pb, Cr and other toxic heavy metals and fluoride wastewater, etc.) and in oil drilling, leather making, metallurgy, papermaking, etc also have a wide range of USES.

alumina desiccant performance and USES

Activated alumina desiccant non-toxic, odourless, not powder, insoluble in water. Under certain operating conditions and the conditions of regeneration of its depth up to the dew point temperature below 70 drying, drying is a kind of trace water depth of efficient desiccant. Widely used in petroleum and chemical gas, liquid and dry, air filter, air compressor air intake equipment and automation instrument air dry.

activated alumina fluoride removal agent

Activated alumina fluoride removal agent, and home fluoride cylinder supporting the use of built-WHA-104 Fluor 1.6 kg, water inlet from below, above, the, fluoride-cylinder operation is simple, easy to use and is ideal for drinking water in addition to the family fluorine devices. The Fluor also be used with water plants fluoride device or devices supporting the use of fluoride for industrial use.
Household fluoride activation means fluorine agent: Configuration aluminum sulfate solution (3 liters of water, 0.3kg of solid aluminum sulfate), aluminum fluoride removal agent net into the above solution for 5-10 hours to extract discarded (when soaked appropriate stirring) and then rinse washed 3-5 times per 2 liters of water.
Household Fluor regeneration: with aluminum sulfate solution with activated using the same solution will be regenerated alumina fluoride removal agent into the solution soak for 30 hours, discard immersion (immersion in an appropriate mixing) and then washed with water and then 3-5 times, each about 2 liters of water. Regeneration or by adjusting PH PH, controlled at 7.5.
Activated alumina fluoride removal agent 6-8 years of continuous use, when the surface appears brown when the effect of fluoride removal significantly reduced, the Department of impurities in the water due to contamination, and thus preferably every six months with 3% hydrochloric acid treatment time, and its operation Methods and regeneration in the same way.

Role of activated alumina

Activated Alumina to the gas , water vapor and some liquid absorption ability selectively . After adsorption saturation at about 175-315 heated to remove water and resurrection . Adsorption and resurrection can be repeated . Except for the drying , but also from contaminated oxygen, hydrogen, carbon dioxide , natural gas, oil vapor adsorption . And used as catalysts, catalyst carriers and the color layer carrier.

Activated alumina is the scope of alumina chemicals , mainly used adsorbents , purifying agent, catalyst and catalyst carrier , depending on the purpose of its raw materials and preparation methods are different.
