摘要:
The present invention relates to spherical agglomerates based on zeolite(s) and clay(s), having controlled size and morphology, in particular a size of less than or equal to 600 µm, very good sphericity, and a high content of zeolitic material, and also to the process for the production thereof. These agglomerates are particularly suitable for uses in gas-phase and/or liquid-phase adsorption processes.
摘要:
The invention concerns an absorbent composition comprising: (a) at least 50 wt.-% of the overall composition have a particle size of less than 150 μm and are comprised of at least one absorbent component; and (b) at least 1.0 wt.-% of the overall composition have a particle size of at least 250 μm and are comprised of at least one particulate component, and its preferred uses.
摘要:
A method for removing a halogen based gas which comprises contacting a gas containing a halogen based gas being at least one selected from the group consisting of F 2 , Cl 2 , Br 2 , I 2 , and a compound forming a hydrogen halide by hydrolysis, with granules containing 80 to 99.9 mass % of an alkali metal base and 0.1 to 20 mass % of a thiosulfuric acid salt, all percentages being relative to the total mass of the granules, in the presence of water, to thereby remove the above halogen based gas; and an agent for removing a halogen based gas for use in the above method. The above method exhibits high capability for treating a halogen based gas, can inhibit the ignition of adsorbing agent, is free from the formation of carbon monoxide and can reduce the amount of a solid waste generated.
摘要:
The invention relates to a composite material of high cohesive strength, formed from at least one polymer and from at least one compound that is chosen from mineral oxides, aluminosilicates and active carbon, said composite material possessing: a mean particle size of at least 100 mm, a pore volume (Vd1) formed by pores with a diameter of between 3.6 and 1000 nm, equal to at least 0.2 cm3/g, a cohesive strength such that its content of particles with a size of less than 100 mm, obtained after being subjected to an air pressure of 2 bar, is less than 1.5%, preferably 0.0%, by volume. The invention also relates to a method of preparing said composite material. It also relates to the use of this composite material as liquid support, catalyst support, additive, or for liquid or gas filtration, in particular in cigarette filters.
摘要:
Aspects of the present disclosure provide composite carbon blocks with improved capacity for the removal of contaminants such as THMs (trihalomethanes) and trace VOCs (volatile organic compounds) found in water. In one aspect, a filtration matrix comprises a polymeric binder and an adsorptive media comprising activated carbon having a bulk density of 0.54 (0.57, or even 0.60) g/cc or greater. The carbon BET surface area can be 1100 (950, or even 550) g/cc or less. The polymeric binder can be ultra high molecular weight polyethylene. Also provided are methods of making filtration matrixes.
