Opis:
The paper presents an exploratory study regarding the sorption capacity of the ash from arboreal biomass, generated by self: combustion in a thermoelectric power plant. Biomass is one of the most promising sources of renewable energy in natural and economic conditions in Poland. The fuel derived from forest areas and specific energy crops, is becoming more widely used due to legislative considerations and needs for sustainable management of natural resources. It creates an increasing amount of waste from a thermal conversion of biomass (combustion by-products) - mainly in the form of ash. Thermoelectric power plants are obliged to manage combustion bv-products. By-products of combustion are utilized, stored or managed depending on the nature of the applied fuel and the waste code, and also according to the regulations. Technologies concerning their economic application allow reducing the amount of.waste and thereby limiting their damage on the environment. The research deals with the ash from arboreal biomass collected from the thermoelectric power plant in Kielce. The research considers the possibility of its application in order to remove pollution from municipal wastewater and leachate from municipal landfills. The adsorption levels were determined using the analysis of kill concentration in solution before and after adding the ash. The ion concentration was examined by means of an atomic absorption spectrometer. The results and sorption properties of ash were evaluated within defined process parameters (pH, temperature, reaction time).

Opis:
The residues from coal combustion are classified as a byproduct harmful to the environment, difficult for transportation and use. These are mainly fly and bottom ashes and slag. Although some of them find practical application, mainly in the construction industry, the majority is still stored. This is particularly true for ashes from power plants. Understandably, the disposal of ashes is of great ecological and economic importance. Recycling and recovery are the best available options here. Foreign experiences have shown that fly ashes can be a valuable resource for production of synthetic zeolites. Natural zeolites are used in numerous economic and industrial sectors. Their limited resources raise the need to look for and apply synthetic products. Since fly ashes obtained from coal are similar to natural zeolites in terms of structure and chemical composition, it is possible to use them as a raw material for the synthesis of zeolites. The aim of the research was to assess the possibility of zeolite synthesis from fly ash - obtained from the municipal power plant – by means of chemical conversion method. In the experiment, the coal ash collected from under electrostatic precipitators in Kielce Power Plant was used. The effect of chemical activation on the sorption properties of coal ash was examined. The chemical conversion consisted in fly ash – NaOH solution interaction under specified temperature and pressure. The influence of changes in the structure of individual grains of fly ash (SEM studies) on their sorption properties was estimated. The level of adsorption on the model stand was tested by means of spectrophotometric method using methylene blue. The modification results and sorption properties of ashes for the set parameters (NaOH concentration, temperature, reaction time) were assessed. The microscopic and X-ray observations as well as specific surface changes indicate that after modification new crystal structures improving sorption capacity were obtained. The aim of the paper is to assess the possibility of utilizing the furnace waste from Kielce Power Plant. A necessary condition for the recovery and utilization of the waste is to identify their characteristics and properties.
