Description

A kind of many plants modification composite activated carbon grain with desulfidation and preparation method thereof

Technical field

The present invention relates to a kind of desulphurized aetivated carbon and preparation method thereof, particularly a kind of many plants modification composite activated carbon grain with desulfidation and preparation method thereof.

Background technology

Cordate houttuynia taste is pungent, cold, returns lung channel.Clearing heat and detoxicating, detumescence can treat sore, promoting urination and removing dampness, clearing away heat to cure dysentery, stomach strengthening and digestion promoting, by the lung carbuncle, sore swollen toxin, hemorrhoidal hemorrhage, retention of heat in the spleen and stomach etc. of controlling real heat, heat poison, damp evil, disease heat are trouble.Modern pharmacology experiment shows, this product has antibacterial, antiviral, effect such as raising immunity of organisms, diuresis etc.Betel nut is the raw material of of inferior quality catechu, and its main alkaloid is arecaline, and animal doctor is used as anthelmintic.Banksia rose surface yellowish-brown or taupe.Cork removes mostly, has obvious longitudinal furrow and root trace, matter is solid, body weight, non-frangibility, section lark, San You dark brown grease chamber point, and cambium ring is brown, have radial texture, and how dry and decayed old root central authorities are, and gas fragrance is strong and special, and bitter is pungent.With solid, bar is equal, fragrance is dense, the large person of oiliness is good.There is certain antibacterial effect.

In numerous methods of desulfurization, have a kind of method to be active carbon adsorption, although active carbon can adsorb multiple sour gas, active carbon price is higher, and desulfuration efficiency is low, adds cost.Active carbon is combined with the diatomite with special porous by the present invention, there is by adding betel nut, the banksia rose, cordate houttuynia etc. the plant of antibacterial effect, make particulate material, make desulfurizing agent adsorption effect better, easily fixing, safety non-toxic, strengthens rigidity and the intensity of product, extend the service time of active carbon, reduce the cost of dry desulfurization.
