Diluter for exhaust gas sampling and method therefore

The purpose of the present invention is to dilute the exhaust gas, providing a constant dilution ratio, regardless of the upstream exhaust gas pressure, without using any moving parts. The proposed diluter utilizes a very small fraction of the exhaust gas (of the order of 0,5 lpm), which is sampled ...

Production and Application of Special Coke for Environmental Purposes

A two-stage activation procedure (pyrolysis under nitrogen flow, followed by activation under carbon dioxide atmosphere) was used for the production of suitable for Hg and PCDD/F removal activated samples. Sulphur impregnation of activated carbons was performed by heating them with high purity eleme...

Leaching and Toxicity Behavior of Coal–Biomass Waste Cocombustion Ashes

The leachability of trace elements from lignite, biomass, and blends cocombustion ashes was investigated by using the Toxicity Characteristic Leaching Procedure (TCLP) of the US Environmental Protection Agency (US EPA). In this work, the toxicity of the aqueous leachates and the concentrations of th...

Production of special activated carbon from lignite for environmental purposes

A treatment technique involving three sequential stages (demineralisation, activation and sulphur dispersion) was developed for the production of suitable activated carbons. Demineralisation included three steps of acid treatment and samples received were characterised by X-ray diffraction (XRD). A ...

Thermal exploitation of wastewood with lignite for energy production

Blends of natural wood, demolition wood, railroad sleepers, medium-density fiberboard residues, and power poles with lignite were used, and the co-combustion efficiency and the effect of wastewood addition on the emitted pollutants were investigated. Carbon monoxide, sulfur dioxide, and oxides of ni...
