Coaltofuel technologies feature high efficiency energy conversion and environmental advantages. While a number of factors are driving coaltofuel projects forward, there are several barriers to wide commercialization of these technologies such as financial, construction, operation, and technical risks.
Jun 15, 2014018332Underground coal gasification UCG is a promising technology to reduce the cost of producing syngas from coal. Coal is gasified in place, which may make it safer, cleaner and less expensive than using a surface gasifier. UCG provides an efficient approach to mitigate the tension between supplying energy and ensuring sustainable development. However, the coal gasification
Nov 01, 2018018332Putting all the aforementioned benefits aside, there is a global rush to decrease coal consumption for power generation. This is because traditional coalfired power plants emit high levels of greenhouse gases GHGs primarily carbon dioxide CO 2 and pollutants such as nitrous oxide NO X, sulphur dioxide SO 2 and particulates .Natural gas is the most viable alternative to coal for ...

Mar 23, 2015018332With Indonesia having large reserves of coal, estimated at more than 6bn tons, Jakarta has been considering several coaltoliquids CTL plants to increase domestic supplies of fuels. The first of these is a facility planned to be built in Southern Kalimantan at an estimated cost of 1.3bn.
Comparative tests have been made in combustion turbine burners between six coal derived liquid CDL fuels and No. 2 distillate oil. All CDL fuels were evaluated in a halfscale by diameter combustor test rig, while one CDL fuel was also evaluated in a full scale high pressure combustion rig.

Box 1 Common gas measurement units. The basic unit of energy is the joule. The common energy unit used in the gas sector is the megajoule MJ or one million joules. Gas volumes in either cubic metres or cubic feet and weights liquefied natural gas LNG in tonnes units used to quantify gas reserves or resources or production of LNG can be readily converted via appropriate factors to joules.
The same goes for natural gas, which will remain the main source of chemicals and energy for the heavyduty industries such as steel, aluminum, cement and paper.

Working Document of the NPC Global Oil amp Gas Study Made Available July 18, 2007 TOPIC PAPER 18 COAL TO LIQUIDS AND GAS On July 18, 2007, The National Petroleum Council NPC in approving its report, Facing the Hard Truths about Energy, also approved the making available of certain materials used in the study process, including
Gray, D., et al. August 1, 2012. Topic Paper 8 Production of Alternative Liquid Hydrocarbon Transportation Fuels from Natural Gas, Coal, and Coal and
Modest growth in industrial coal consumption is due in part to rising use of coal as a feedstock for a range of conversion processes, notably coaltogas and coaltoliquids projects in China. Overall coal consumption flattens around 5 400 million tonnes of coal equivalent Mtce and does not regain the peak seen in 2014. The supply projections ...
Amid all the attention to the converging of three energyrelated crises climate change, resource depletion and international extremism funded by the energy trade a surprising energy choice keeps rearing its head coal. That especially includes liquid fuels made from coal, which can be a substitute for gasoline, jet fuel and just about any other transportation fuel on which we currently ...
The present revision paper discusses and introduces different alternative fuels that can be burned in IC Engines and would eliminate, or substantially reduce the emission of fossil CO2 into the ...
Despite a cold start to winter, natural gas prices have plummeted to 2.66MMbtu in February. The rapid decline followed record breaking natural gas production and a warm December and January. As a result, coal to gas switching should be a hot topic again this summer. BTU Analytics reviewed coal to gas switching potential in 2016 Coal to Gas Switching 2019 Read More 187

Thus, the development of poison resistant catalysts that function with both coal and biomass gasification, will significantly advance coalbiomasstoliquids CBTL technology. Coal gasification followed by FischerTropsch synthesis has been commercially demonstrated for producing sulfurfree diesel and other middle distillate fuels for over 50 ...
Dec 05, 2011018332At present, hydrogen from coal can effectively be used in chemical plants for the production of ammonia and fertiliser by substitution of the hydrogen produced from natural gas. The coal to liquid fuels process based on FischerTropsch synthesis is attractive only when exceed 87, 140 and 100 bbl for scenarios 1, 2 and 3, respectively.
