Underground Coal Gasification - A Status Report [PDF]
Journal of Petroleum Technology, 1977 Underground gasification provides a unique means for recovering energy from coal without mining it. ERDA is conducting several field demonstration projects to test the feasibility of in-situ coal gasification. Several projects to test the feasibility of in-situ coal gasification. Several concepts being tested are discussed.

Status of Underground Coal Gasification: ABSTRACT
AAPG Bulletin, 1985Underground coal gasification appears to be one of the most attractive routes for synfuels from coal because the process can produce methanol and substitute natural gas at prices competitive with existing energy sources. The technical feasibility of underground coal gasification has been well established by small-scale field tests. Cost estimates based

Method for Stimulating Underground Coal Gasification
Journal of Mining Science, 2018The mathematical model of heat flow and transfer in roof rocks of underground gas gasifier during coal gasification is developed and tested. In terms of geological conditions in the Olkhovo-Nizhnee site (industrial region in Donbass), in Mathcad environment, convective and conductive components of heat flow from reaction channel to upper-lying aquifer ...

Steam decomposition in underground coal gasification
Industrial & Engineering Chemistry Research, 1987An idea for probing the combustion zone temperature (CZT) in underground coal gasification (UCG) by using the hydrogen amount in product gas coming from the steam decomposition (HS) is proposed. It seems, from both experimental and theoretical analyses of three generators, that the increase in CZT results in the increase of HS and vice versa ...

Underground coal gasification: issues in commercialisation
Proceedings of the Institution of Civil Engineers - Energy, 2014Back in 2007, it was expected that commercial gas production from underground coal gasification (UCG) technology would be in progress within the following 5 years. This has not occurred, particularly in Australia, where at the time three commercial projects were being aggressively pursued.

Producing hydrocarbons by the underground gasification of coal
Coke and Chemistry, 2013The composition and yield of the products obtained in the underground gasification of coal at Podzemgaz South Abinsk Station are studied. Data are also presented regarding the rectification and hydrocracking of the products. The underground gasification of coal may be regarded as a potential source of phenolic hydrocarbons, naphthalene, pyridine bases,

Commercial development of underground coal gasification
Proceedings of the Institution of Civil Engineers - Energy, 2007Underground coal gasification (UCG) is a process by which coal seams at depths uneconomic for open pit mining can be converted, using drillhole access, to a gas suitable for use as a fuel for power generation or as a chemical feedstock. Its application draws on a wide range of engineering and related disciplines including chemistry, geology ...

In-Situ Processes: Underground Coal Gasification
1981The idea of recovering the energy values of coal by in-situ processes, without the intervention of human effort below ground and without bringing waste to the surface, is one which has exceptional appeal to the public. For this reason alone, a careful analysis of the possibilities is desirable, regularly renewed in the light of developing technology ...

CFD Simulation of Underground Coal Gasification
2012Underground Coal Gasification (UCG) is a process in which coal is converted to syngas in-situ. UCG has gained popularity recently as it could be used to extract energy of deep-lying coal seams, and it reduces the footprints attributed to the gasification process.
