Entrained flow gasification of biomass using the cyclone principle has been proposed in combination with a gas engine as a method for combined heat and power production in small to medium scale (<20 MW). This type of gasifier also has the potential to operate using ash rich fuels since the reactor temperature is lower than the ash melting temperature and the ash can be separated after being col...

The article presents research on the preparation of raw materials, creation and granulation compositions from obsolete sludge deposits peat biomass. Studies material processes have shown that excessive ash content. To reduce content, it is advisable to add biomass sludge. During study peat, was determined extracted floodplain Irpen has a high so for further used Chernihiv.&#x0D; created were su...

The physico-chemical characteristics as well as chemical composition of Arachis hypogaea shell (AHS) ash were evaluated by different techniques such as X-Ray fluorescence, X-Ray diffraction and thermo-gravimetry. The material, which is considered a by-product obtained from Groundnut shelling, was investigated as a potential fertilizer, energy source and as animal feeds. And this will provide a ...

Methanogens (domain Archaea) have a unique role in the carbon cycle as producers of the greenhouse gas methane (CH(4)). Methyl-coenzyme M reductase (MCR) is a vital enzyme in CH(4) production, and the mcrA gene coding for a subunit of MCR has been employed as a specific marker for the detection and differentiation of methanogen communities. A critical step in assessing environmental mcrA divers...

Ombrotrophic peat bogs form an independent ecosystem fed entirely by atmospheric deposition. Ombrothropic peat preserves the record of deposition of metals of crustal origin and anthropogenic origin that is, caused by industrial, agricultural and other human activities. Two cores each of 40 cm length were taken f?om the peat bogs in southern Poland and the alpine region in Austria. The cores we...

In the presented paper analysis of sensitivity of self-attenuation correction Cs to the accuracy of chemical composition analysis is presented. The analyses were done by means of Monte Carlo simulation for cylindrical samples and for four sample materials: peat, water, ash and soil. For each of these materials the major elements were selected whose determination in the analysed material is nece...

* E-mail: [email protected] ABSTRACT Effluents of textile dyeing are characterized by intense colour, chemical oxygen demand, suspended solids and a variety of refractory matter, such as heavy metals and nonionic surfactants. Strong colours may reduce light penetration, thus affecting the growth of plants and having impact on invertebrate and other forms of wildlife. There are a large numbe...

The intensive use of lead (Pb)-based insecticides (lead arsenate, PbHAsO4) has led to Pb accumulation in agricultural soil, endangering human health through the possibility transferring it food chain. aim this study was evaluate potential for immobilization soil by applying organic (sludge, biocompost, yard compost, and peat) inorganic (bonemeal, zeolite, lime, wood ash) amendments, combination...
