Underground coal gasification (UCG) is a promising option for the future use of un-worked
coal. UCG permits coal to be gasified in situ within the coal seam, via a matrix of wells. The …

Underground coal gasification can convert deep coal into synthesis gas for use in the
production of electricity, fuels and chemicals. This paper provides a review of the …

This paper represents the results of experimental studies of physical modeling of the
underground coal gasification process in terms of implementation of design and …

Abstract Underground Coal Gasification (UCG) is an emerging technology that utilizes
unmined coals. In UCG process, coal is burned and gasified underground. Produced syngas …

Several hybridization strategies of a solar-autothermal biomass gasifier were examined for
stable and continuous operation under variable solar irradiation. The ultimate objective was …

This paper describes an experiment of underground coal gasification in experimental
equipment. The experiment was done within the range of the project APVV-0582-06, in May …

Hydrogen is a clean energy source, and its use helps to mitigate climate change.
Underground coal gasification for hydrogen production is a promising method for countries …

A 72-h ex situ hard coal gasification test in one large block of coal was carried out. The
gasifying agent was oxygen with a constant flow rate of 4.5 m3/h. The surroundings of coal …

The conversion of waste to energy through briquetting has the potential for providing energy,
while simultaneously reducing wastes and their environmental health risks. The current …

Underground coal gasification is a complex physico-chemical process. UCG thermodynamic
equilibrium model was established and validated, and the effects of the steam-to-oxygen …
