The raw materials of water treatment activated carbon have coconut shells, walnut shell, apricot, peach shell, wood, coal and so on, the coconut shell activated carbon is considered the best water treatment activated carbon. Water treatment activated carbon has powder, granule and columnar, among them granule is the most widely used. The smaller granularity, the faster absorption, but head loss increases, usually in 8-30 mesh is better.

Activated alumina adsorbent is white spherical porous granules, surface smooth, uniform particle size, non-toxic, odorless, tasteless, insoluble in water, alcohol and organic solvents, but insoluble in acids and alkalis. Activated alumina has strong moisture adsorption, does not burst after absorbing water, possesses big mechanical strength, specific surface area and pore volume.

Molecular sieve also called zeolite, is a crystalline aluminum silicate. Its crystal structure has neat and uniform channel, aperture around a molecular level, molecular sieve only allows smaller diameter than its aperture into it, so it can sieve molecules according to their size in the mixture, so it called molecular sieve. According to molecular sieve aperture size, there are 3A, 4A, 5A, 10X, 13X. 4A molecular sieve is Na-A molecular sieve, aperture 0.4nm; if Na replaced by K, aperture 0.3nm, is 3A molecular sieve; if over 1/3 Na replaced by Ca2+, aperture 0.5nm, is 5A molecular sieve.

There are type A silica gel, type B silica gel, type C silica gel, silica gel cat litter, silica alumina gel, blue silica gel, orange silica gel, FNG silica gel, pressure-changing adsorption silica gel Added dilute sulfuric acid (hydrochloric acid) into the aqueous solution of sodium silicate and let standing, thus becoming solid aqueous silicate gel. Used water washing to remove Na+ and SO4 2- (Cl-) ions dissolved in the electrolyte, after drying it is silica gel...

Ring), fenske spiral, glass spring packing, cannon packin

Ceramic honeycomb has many advantages such as small size, light weight, large surface area, high refractoriness, high heat capacity, low air flow resistance loss, and so on. Compared with regenerative ball, honeycomb ceramic is more difficult to plug straight airflow path; honeycomb ceramic regenerative chamber volume also significantly reduced, a sufficient amount of burners can be arranged to meet the needs of the thermal load. Honeycomb ceramic can guarantee temperature uniformity, rapid heat

Activated alumina is white spherical porous granules, smooth surface, uniform particle size, non-toxic, odorless, tasteless, insoluble in water, alcohol and organic solvents, but insoluble in acids and alkalis. There are the following types of products: activated alumina desiccant, activated alumina defluorination agent, activated alumina catalyst carrier, activated alumina for hydrogen peroxide, activated alumina sulfur recovery catalyst, potassium permanganate alumina, dechlorination agent

There are the following types of products: 3A molecular sieves, 4A molecular sieves, 5A molecular sieves, 13X molecular sieves, insulating glass desiccant, refrigerant desiccant, clay desiccant, carbon molecular sieves, container desiccant Molecular sieve adsorption capacity come from physical adsorption (Van der Waals forces), its cavities have a strong polarity and coulomb field which show a strong adsorption capacity to polar molecules (such as water) and unsaturated molecules.

According to user’s requirements, different production methods are applied such as chemical method, physical method, chemical-physical or physical-chemical method. The most common use of activated carbon is air purification, water treatment, catalyst carrier. Air Purification Activated Carbon is made of wood, coal or coconut shell, granular or cylindrical appearance. The raw materials of water treatment activated carbon have coconut shells, walnut shell, apricot, peach shell, wood, coal.

Added dilute sulfuric acid (hydrochloric acid) into the aqueous solution of sodium silicate and let standing, thus becoming solid aqueous silicate gel. Used water washing to remove Na+ and SO4 2- (Cl-) ions dissolved in the electrolyte, after drying it is silica gel. Different manufacturing methods form different microporous structure, different microporous structure form different models, such as macroporous silica gel, silochrom (type C), type B silica gel, fine-pored silica gel(type A)

Between crystallite of activated carbon have many spaces with different shape, size and certain strength. According to the aperture size these spaces are generally divided into big pore (>50nm), mid-hole (2.0-50nm) and micropore (<2.0nm). 90% specific surface area of activated carbon comes from micropore, its specific surface area can reach more than 1000m2/g, and pore volume also is large, so micropore is an important factor decided adsorption performance of air purification activated carbon.

Yuanying Molecular sieve can be widely used in industry, for example, purifying the gas in the air separation device, removal of H2O, CO2 and hydrocarbons; natural gas, liquefied petroleum gas, liquid alkanes (propane, butane) dehydration and desulphurization (removal of H2S and thiol); general gas (such as compressed air, permanent gases) depth drying; ammonia synthesis gas drying and purifying; aerosol, propellant desulfurization and deodorization; pyrolysis gas removal of CO2;

Due to the unique porous bone structure, high specific surface area and in an unstable transition state, activated alumina has biggish activity, strong affinity with active ingredient. Activated alumina has a number of capillary channels, its selective adsorption not only determined by its micro-holes diameter size, but also according to the polarity of the adsorbed materials.
