Process for coal gasification Syracuse Research

What is claimed is: 1. An improved process for the gasification of coal, comprising the steps of introducing a member of the group consisting of gaseous anhydrous ammonia, liquid anhydrous ammonia, aqueous ammonia and combinations thereof and methanol into a coal seam, allowing said member to remain in contact with the coal in said coal seam for a long-enough period to increase substantially

Gasification of Coal Biofuels Academy

2017-4-20  Gasification of Coal. Coal gasification is the process of producing coal gas, a type of syngas–a mixture of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2) and water vapour (H2O)–from coal and water. Coal gas, which is a combustible gas, was traditionally used as a source of energy for municipal lighting and heat before the advent of industrial-scale production of natural gas

Process for in situ coal gasification Ramcor, Inc.

I claim: 1. A process for in situ gasification of coal to produce a combustible methane rich product gas which comprises injecting a lower aliphatic alcohol into an underground coal seam, raising the temperature of the seam sufficiently to cause vaporization and dissociation of the alcohol into carbon monoxide and nascent hydrogen and initiate a hydrogasification reaction, within the coal seam

Modeling and Analysis of Coal-Based Lurgi

A coal-based coproduction process of liquefied natural gas (LNG) and methanol (CTLNG-M) is developed and key units are simulated in this paper. The goal is to find improvements of the low-earning coal to synthesis natural gas (CTSNG) process using the same raw material but producing a low-margin, single synthesis natural gas (SNG) product. In the CTLNG-M process

Underground Coal Gasification (UCG)

Underground gasification could potentially allow the use of coal that is currently uneconomical to mine. Underground gasification eliminates the need for strip mining and transportation of coal, as well as potentially making carbon capture and sequestration more practical. However, UCG produces large amounts of CO2, and the coal combustion

Underground Coal Gasification (UCG)

Underground Coal Gasification (UCG) involves igniting coal in the ground, then collecting and using the gases that result from its partial combustion.Although the idea dates back over a century, very few UCG plants have ever been built. Underground gasification could potentially allow the use of coal that is currently uneconomical to mine.

Clean Coal Technology related to Coal

Coal is more abundant and cheaper than oil and natural gas, but it exhausts high carbon dioxide gas (CO 2) and sulfur content of the environment load at the time of the use. Clean coal technology (CCT), which uses coal in high efficiency and clean, is a key technology to reduce the discharge of the material having high environmental load.

Dual extraction process increases mining safety

Mathematical Modeling of the Underground Coal

2020-3-4  Underground coal gasification (UCG) has its own reaction characteristics with the growth of the combustion cavity because the coal seam is fixed while the gasification face moves. The theoretical understanding of UCG requires continuous and deep research. In order to explain the UCG mechanism by means of simulation calculation, based on the analysis of the reaction process of UCG, radial and

Clean Coal Technologies Inc set to revolutionize coal

Clean Coal Technologies Inc's breakthrough

2019-9-4  The coal cleaning process ensures the carbon in coal maintains its structural integrity during the heating process, while the volatile matter — often polluting heavy metals — turns into liquids and gas and escapes the coal. The technology is handy as deposits with high moisture coal emit less energy than low moisture coal.

UCG-GTL Australian UCG Underground Coal

Underground coal gasification (UCG) is an in-situ gasification process carried out in non-mined coal seams using injection and production wells drilled from the surface, which enables the coal to be converted into product gas.
