The economic viability of producing synthetic natural gas (SNG) through coal gasification is heavily dependent on the market prices of natural gas and the coal feedstock to be used, in addition to the capital cost of the gasification plant.
The invention and installation of scrubbers to remove solids, sulfur oxides, nitrogen oxides and other byproducts from coal emissions continually get better, for example, especially when combined with capandtrade regulations that align market incentives with environmental objectives.

SYNTHETIC FUELSSynthetic fuels are usually thought of as liquid fuel substitutes for gasoline and diesel fuel made from petroleum sources. In broad context, the source of these synthetics can be any feedstock containing the combustible elements carbon or hydrogen. These include coal, oil shale, peat, biomass, tar sands, and natural gas. Source for information on Synthetic Fuels: Macmillan ...
Gasification is a technological process that can convert any carbonaceous (carbonbased) raw material such as coal into fuel gas, also known as synthesis gas (syngas for short). Gasification occurs in a gasifier, generally a high temperature/pressure vessel where oxygen (or air) and steam are directly contacted with the coal or other feed material causing a series of chemical reactions to ...
The insitu gasification process (ISG) produces methane, hydrogen and other valuable components. The synthetic gas (syngas) can be used to produce electricity directly or further refined into a variety of products including synthetic methane and ammonia. The ISG demonstration project was built to inform the design for a potential commercial ...
DCL technology involves making a partially refined synthetic crude oil directly from coal, which is then further refined into synthetic gasoline and diesel as well as liquefied petroleum gas (LPG). ...

[1] Synthetic natural gas is a type of gas created from coal that serves as a substitute for natural gas and is suitable for transmission in natural gas pipelines. This natural gas substitute must have a minimum of 95% methane in it. [2]
Covers technological, and economic aspects of this Synthetic Natural Gas; Details the most popular technologies and stateoftheart of SNG technologies while also covering recent and future research trends; Covers the main process steps during conversion of coal and dry biomass to SNG: gasification, gas cleaning, methanation and gas upgrading
Production of synthetic crude oil from coal using the Toscoal pyrolysis process. Conference Cortez, D; LaDelfa, C Proc., Intersoc. Energy Convers. Eng. Conf.; (United States) This paper presents the results of a recent feasibility study of the Toscoal process for recovering oil and gas from coal prior to combustion in power plants. Conceptual ...
For example, it is possible to produce synthetic jet fuel, diesel, or gasoline for conventional planes, ships, trucks, and cars. The main difference between fossil and synthetic fuels is how they are produced: fossil fuels are formed over millions of years underground from organic matter that is turned into coal, natural gas, or oil.
Technology has come a long way since the first coalderived liquid fuel (a synthetic crude oil) was produced through direct liquefaction in the early 1900s. In 1925, Franz Fischer and Hans Tropsch used an indirect liquefaction process, which still bears their name, to produce excellent transportation fuels. Germany had 25 liquefaction plants ...
coal resources: it contains 25% of the world's coal reserves, and the energy content of those reserves exceeds the energy content of the world's known recoverable oil (DOE 2008). Still, increasing consumption—and the resultant increasing price—of natural gas are
Synthetic natural gas production process overview. In Section 3 of the paper, researchers presented various processes used to generate SNG through renewable and nonrenewable methods. Where nonrenewable methods use coal, and renewable methods use biomass in the form of wood, agricultural waste, manure, amongst others.
In the 1960s and 1970s, Lurgi's coal gasification process, developed in the 1930s in Germany, was the only commercially viable technology applicable for the production of synthetic natural gas in pipeline quality. Lurgi developed a methanation unit including two adiabatic fixed bed reactors with internal recycle.
Both the FischerTropsch and MTG processes convert coal into synthesis gas before converting it to the final liquid products. However, their respective product slates are very different.
This process converts the coal into a synthetic crude oil. ... Production of synthetic gasoline and diesel fuel by alternative processes using natural gas and coal: process simulation and optimization. Energy, 34 (12) (2009), pp. . View PDF View article View in Scopus Google Scholar
A compiling of the fundamental process to produce synthetic fuels from coal, oil shale, and oil sand was presented formerly by Hendrickson (1975) ... (2006) categorize synthetic fuel development in three main periods [108]: (i) : Development of the coal liquefaction by means of hydrogenation, and the FischerTropsch (FT) synthesis from;
The primary process for FT is the Synthol Process; the schematic is shown in Figure The synthesis gas goes into the reactor at MPa of pressure and 315330°C. The product leaves the reactor where the catalyst is recovered, oils are removed by a hydrocarbon scrubber, and the tail gas recovered.
24 August, 2005. Sasol has produced almost 1,5 billion barrels of synthetic fuel from about 800 million tonnes of coal since the first sample of synthetic oil from coal was produced fifty years ago at its Sasolburg plant near Johannesburg in South Africa on 23 August 1955. Regarded as a world technology leader in the production of coalto ...
Without carbon capture technology, coaltoliquid fuel produces twice the emissions as gasoline from conventional crude oil: about 50 pounds of CO2 for liquid coal compared with 27 pounds for conventional gasoline. Coaltoliquid is also a waterintensive process, using about ten gallons of water for every gallon of fuel produced.
Coal liquefaction is a process in which coal is converted into liquid fuels or petrochemicals. There are several processes used to accomplish this task, the two most common being the "indirect route" and the "direct route". ... The second step reacts the synthesis gas with a catalyst in the FischerTropsch process, which converts the syngas ...
The beginning of the history of synthetic fuels datesgaso to 1913 when the first process of direct coal liquefaction (DLC) by mean of hydrogenation was patented in Germany by the chemist Friedrich Karl Rudolf Bergius () The basic principle of DLC was the use of coal instead of petroleum/crude oil to obtain liquid hydrocarbons used for fuel or as a base for producing other chemicals.
