The main objective of submitted paper is to determine heavy metals distribution between different ash fractions during thermochemical conversion of contaminated biomas in fluidized bed reactor. Moreover, heavy metals behaviour in oxidation and reduction reaction atmosphere is different; hence comparison of heavy metals distribution during gasification and combustion of the same fuel is introduced.

This study was aimed at determination of distribution of heavy metals among producer gas and individual size fractions of ash matter, i. e. bed ash and cyclone ash, formed in fluidized bed steam biomass gasification. Knowledge of distribution of heavy metals is necessary for further utilization of all products of the gasification.

The aim of this project was to evaluate the effect of addition of CO2 to the gasification agent during allothermal steam fluidized bed gasification of biomass at constant temperature about 800 °C. Moreover, the effect of different fluidized bed materials such as silica sand and limestone together with the effect of temperature on producer gas composition was also examined. Experiments led to conclusions that CO2 added to the gasification agent was converted to CO to only very limited extent while CO2 dilution effect was relatively strong. The CO2 to CO conversion was exhanced by the use of limestone as the bed material. Limestone showed also strong catalytic activity towards reduction in tar content in the producer gas and higher production of H2, CO2 and CO in comparison with silica sand. Optimal temperature for in the bed-use of limestone in the gasification process was proposed to be around 850 °c under the given experimental conditions.

Principles of Gasification Technology; Literature Review
Hanika, Jiří ; Jiřičný, Vladimír ; Punčochář, Miroslav ; Veselý, Václav ; Vosecký, Martin
The present review deals with gasification technologies in relation to rape grouts, which is relevant fuel at the project. Fundamentals about several gasification technologies, such as in fixed-bed, fluidized-bed and entrained flow, are discussed. Moreover, an overview of gasification units which are based on the relevant technologies is stated.

The gaseous product from gasification (producer gas) can be effectively utilized in a variety of ways including power generation, production of chemicals, fuels for transport and substitution of natural gas for heating. The gasification technology, needed gas composition and cleaning, tolerable contents of impurities, toxic compounds and heating value of the producer gas are determined usually by the end user of the gas.
