Underground Coal Gasification (UCG) is the process by which coal is converted in-situ into a gas product that can be combusted for power generation or used as a chemical feedstock. UCG exploits coal resources that are either uneconomical to mine with conventional mining methods or are inaccessible due to depth, geology or other mining and ...

This work presents the results of the analyses of tar fractions contained in the process gas during a real underground coal gasification test at the Wieczorek mine in Poland. The samples of tar compounds were collected periodically every two days directly from the process gas during the 60-day gasification test. The coal gasification reagents ...
Acid-base accounting of unburned coal from underground coal gasification at Majuba pilot plant by L.S. Mokhahlane, M. Gomo, and D. Vermeulen /0%*3* Underground coal gasification (UCG) is an unconventional mining method that converts coal in situ into a .
Underground coal gasification (UCG) is a process that converts deep, un-mineable coal resources into syngas, which can then be converted into valuable end products such as electric power. This paper provides a summary of the options to combine UCG with electric power production and focuses on commercial-scale applications using a combined-cycle ...
The book deals with development of comprehensive computational models for simulating underground coal gasification (UCG). It starts with an introduction to the UCG process and process modelling inputs in the form of reaction kinetics, flow patterns, spalling rate, and transport coefficient that are elaborated with methods to generate the same are described with illustrations. All the known ...

Underground Coal Gasification. With underground coal gasification (UCG), the actual process takes place underground, generally below 1,200 feet. The underground setting provides both the feedstock source as well as pressures comparable to that in an above-ground gasifier. With most UCG facilities, two wells are drilled on either side of an ...
Gasification (Contd..) • Gasification as a technology was developed in the early 1800's in Baltimore for town gas production. • Today, gasification of coal is largely directed to the production for Syngas for conversion to ammonia, methanol etc. • For power generation, it is expected to be the highest area of growth in gasification

Introduction. Underground Coal Gasification (UCG) is a mining method that utilizes gasification to produce gas from in situ coal (underground in the coal seam) by injecting combinations of air, oxygen, steam and carbon dioxide (CO 2) as gasification agent into coal seams and extracting the product gas to the surface via boreholes.UCG is a high-extraction mining method operating at least two ...

Keywords: underground coal gasification, syngas, clean coal techno-logy, energy analysis, economic analysis. Coal will remain the leading energy resource in the following decades [1,2], which is why the develop-ment of technologies, which will enable and maintain the coal's competitiveness against other energy res-ources, is expected.
Underground Coal Gasification (UCG) is a gasification process applied to non-mined coal seams, using injection and production wells drilled from the surface, which enables the coal to be converted in situ into product gas. The process has produced commercial quantities of gas for both chemical processes and power generation.
