Abstract
Active carbon for absorbing gasoline steam is prepared by the following raw materials by weight: zinc chloride, 10-14 parts of 20-25% phosphoric acid solution, 10-14 parts of diatomite, 6-9 parts of glass powder, 30-40 parts of kaolin, 15-20 parts of montmorillonite, 25-30 parts of wheat straw, 80-100 parts of branch, 25-30 parts of reed straw, 4-5 parts of modified diatomite, and a proper amount of water. Active carbon using wheat straw, branch and reed straw as raw materials, has advantages of developed aperture structure, big specific surface area and high adsorption speed, and has good adsorption capability to various solutes and free gas; diatomite, kaolin, montmorillonite and glass powder are used to make the active carbon have high mechanical strength and resist wear resistance; and zinc chloride and phosphoric acid are used to activate, so as that the active carbon is suitable for absorbing organic matters like gasoline steam, and also suitable for recovering benzenes and the high boiling solvent.
Description
Technical field
The present invention relates to a kind of modified function Material Field, relate in particular to a kind of gasoline vapor absorption active carbon and preparation method thereof.
Background technology
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.For the active carbon of gasoline vapor absorption use require high to gasoline adsorption capacity, desorb good, intensity good, it is not high that but the shortcoming of common active carbon is intensity, carbon surface floating dust is many, these defects can shorten useful life, increase gas-flow resistance, and because bulk density is little, have to realize and improve adsorption capacity and displacement volume by the mode that improves Unit Weight adsorbance.
