BACKGROUND Exposure to polycyclic aromatic hydrocarbons (PAHs) has been reported in several industries, including those of the aluminum production, coal gasification, coke production, iron and steel foundries, coal tar and related products, carbon black and carbon electrodes production. PATIENTS AND METHODS This paper reviews the results from cohort studies conducted on workers exposed to PAH...

This study presents a preliminary assessment of the environmental impact field-scale underground coal gasification (UCG) targeting deep-buried seams by studying fate UCG products in reactor vicinity. A series simulation scenarios are conducted three deep (900 m) areas specific interest – namely, South Wales coalfield (UK), Upper Silesian basin (Poland) and Ruhr mining district (Germany) to inve...

The effect of fuel composition on gasification process performance was investigated by performing mass and energy balances on a pre-pilot scale bubbling fluidized bed reactor fed with mixtures of plastic waste, wood, and coal. The fuels containing plastic waste produced less H2, CO, and CO2 and more light hydrocarbons than the fuels including biomass. The lower heating value (LHV) progressively...
