Fuel gas for industrial use was made using producer gas technology Producer gas is made by blowing air through an incandescent fuel bed (commonly coke or coal) in a gas producer The reaction of fuel with insufficient air for total combustion produces carbon monoxide (CO); this reaction is exothermic and self-sustaining
GE Energy (Formerly Chevron Texaco) Gasifier | netldoegov
Formerly known as ChevronTexaco and/or Texaco gasifiers (GE Energy acquired the technology in 2004), GE gasifiers have operated commercially for over 45 years using a wide variety of feedstocks such as natural gas, heavy oil, coal and petcoke The coal gasification process was developed by extending experience with gas and oil gasification
The clean coal technology program has resulted in more than 20 new, lower cost, more efficient and environmentally compatible technologies for electric utilities, steel mills, cement plants and other industri Energy and Environmental Benefits of CCT Today
Cleaner, Cheaper Liquid Fuel from Coal - MIT Technology Review
Jan 06, 2012· SRI claims its process addresses three liabilities that have slowed the commercialization of the technology By blending some natural gas into the conventional coal-to-liquids (CTL) process, the .
Synthetic natural gas (SNG) is one of the commodities that can be produced from coal-derived syngas through the methanation process The economic viability of producing SNG through coal gasification is heavily dependent on the market prices of natural gas and the coal feedstock to be used, the value of by-products such as carbon dioxide (CO2) (which could be used for EOR), and additionally the .
Air Products to Acquire Shell’s Coal Gasification ,
“The acquisition of Shell’s technology, already in operation at more than 20 coal gasification plants, gives us access and opportunities to fully explore outsourcing options to produce and supply syngas for customers planning to use gasification,” said Seifi Ghasemi, chairman, president and chief executive officer at Air Products Ghasemi .

Coal gasification: The clean energy of the future? - BBC News
Apr 14, 2014· A very different way to produce gas from coal is known as underground coal gasification (UCG), a process that has been around since the 19th Century but which has yet to become commercially viable .
Office of Clean Coal and Carbon Management | Department of ,
In the longer term, the goal is to increase energy plant efficiencies and reduce both the energy and capital costs of CO 2 capture and storage from new, advanced coal plants and existing plants These activities will help allow coal to remain a strategic fuel for the nation while enhancing environmental protection
If, however, hydrogen is the desired end-product, the coal gas (primarily the CO product) undergoes the water gas shift reaction where more hydrogen is produced by additional reaction with water vapor: CO + H 2 O → CO 2 + H 2 Although other technologies for coal gasification currently exist, all employ, in general, the same chemical process

Coal Gasification Technology - an overview | ScienceDirect ,
Nicholas P Cheremisinoff PhD, Motasem B Haddadin, in Beyond Compliance, 2006 This coal gasification technology is based on an oxygen-blown entrained flow gasifier, where the majority of experience has been gained in a 150 t coal/d unit The gasifier is a water-cooled tube lined by a high-temperature-resistant castable
In traditional coal plants, this takes place in a large boiler, where coal is burned and water is boiled to create high pressure steam This high pressure steam then expands through a steam turbine, creating power In CCGT power plants, natural gas or coal syngas is burned in a combustor with compressed air
