The influence of fly ash zeolites fusion synthesis parameters on the received products

Fly ash is one of possible raw material for the production of zeolites. Synthesis of zeolites with the use of fusion method enables the possibility of receiving materials of high yield of zeolites. This process may be used for efficient recycling of coal waste from power energy sector, which due to legislative indications shall no longer be directed into the landfills. The...

Sorption of pharmaceuticals residues from water to char (scrap tires) impregnated with amines

The study investigated the application of char activated with CO2 and impregnated with amines solutions for removal of selected xenobiotics from aqueous solutions. The chars produced from the pyrolysis of waste tires. The solutions of monoethanolamine (MEA), diethanolamine (DEA) and polyethylenimine (PEI) were used for impregnation of char. The sorption capacity of char...

Sequestration of carbon dioxide – influence of coal surface chemistry

The physical gas adsorption is a widely used method for the characterisation of the solids porosity. The water steam, primarilydue to its physicochemical properties and ease of use in the experiment has great potential as a sorbate. When applied to coal, water steam allows to determine the quantity of primary adsorption centers as measurement of interaction of molecules adsorbed...

Analysis of the influence of fusion synthesis parameters on the SO2 sorption properties of zeolites produced out of fly ash

Fly ash zeolites are interesting alternative for zeolies produced out of pure chemicals as well as for natural zeolites. It can be applied as SO2 sorbents out of flue gases. In the work the experiments were aimed at investigation of SO2 sorption capacity of samples produced out of fly ash in fusion process. The influence of fusion reaction parameters on the type of obtained...

Kinetic models assessment for swelling of coal induced by methane and carbon dioxide sorption

The ability of five kinetic equations to describe the sorption kinetics and expansion rate of solid coal samples was investigated. The conducted experiment included the measurements of sorption of methane and carbon dioxide on cuboidal hard coal samples at high pressure using volumetric method. Simultaneously the kinetics of coal sorption induced swelling was monitored. All of...
