Description
Technical field
The invention belongs to inorganic macromolecule material and microsphere supported field, be specifically related to a kind of with expanded perlite mine tailing for primary raw material absorption VOC with microsphere supported and preparation method thereof.
Background technology
VOC(Volatile
Organic Compounds, VOC) it is organic synthesis industry and the modal pollutant of petrochemical industry discharge, these materials mainly have hydrogen sulfide, thio-alcohol, thioether class, ammonia, amine, hydro carbons, aldehydes, alcohols, phenols, esters and organic halogen system derivant etc..These organic compound have toxicity mostly, and part still belongs to flammable and explosive substance, threatens enterprise safety operation.Adsorption technology has obtained increasingly being widely applied in terms of administering these organic compound from waste gas.
According to the difference of absorption affinity between adsorbate and adsorbent, adsorption operations is divided into physical absorption and the big class of chemisorbed two.Physical absorption is adsorbed also known as Van der Waals, it it is the result of captivation effect between sorbent molecule and adsorption molecule, because its intermolecular adhesion is more weak, therefore be easily desorbed, if the molecular attraction between solid and gas is more than the gravitation between gas interior molecule, gas will condense in the surface of solids, and when adsorption process reaches balance, the vapour pressure of absorption adsorbate on the sorbent is equal to its dividing potential drop in the gas phase.
Chemisorbed is to be caused by the effect of chemical bond between adsorbate and sorbent molecule, adhesion therebetween is more much bigger than physical absorption, liberated heat is the most much bigger, suitable with the chemical reaction heat order of magnitude, process is the most irreversible, during chemisorbed, temperature is more significant on the impact of speed, temperature raises the then rate of adsorption and accelerates, because it is an activation process, therefore also known as activation adsorption.Chemisorbed has higher selectivity simultaneously, as chlorine can be chemisorbed in catalytic reaction play an important role by tungsten or nickel chemisorbed.
The process that adsorbate is adsorbed by adsorbent can be divided into three steps:
First step external diffusion: adsorbate is delivered to the outer surface of absorbent particles from bodies of fluid by diffusion (molecule spreads and Convention diffusion).Because when fluid and solid contact, there is one layer of viscous flow film, so the speed of this step depends primarily on adsorbate and diffuses through the transfer rate of this viscous flow film with molecule being close at the surface of solids.
Second step internal diffusion: adsorbate diffuses into inside granule from the outer surface of absorbent particles by the micropore granule, arrives the interior surface of granule.
3rd step absorption: adsorbate is adsorbed by adsorbent on an internal surface.
For physical absorption, the 3rd step typically moment completes, so the speed of adsorption process is generally determined by the first two step, is divided into according to the relative size of inside and outside diffusion rate: external diffusion control, internal diffusion control and interior external diffusion jointly controls three kinds.
Chemisorbed heat is close with chemical reaction heat, more much larger than physical absorption heat.Such as carbon dioxide and hydrogen, the chemisorbed on various adsorbents is so 83,740J/mol and 62,800J/mol, and the physical absorption heat of both gas is about 25,1
20J/mol and 8374J/mol.
Therefore it provides a kind of bulk density is less, natural hole and artificial interlayer pass as sorbent material and preparation method thereof, are one of the important directions of this area research at present.
