For the same kind of coal-derived fuel production technology using a different mining–transport–production pathway, there is no significant difference in the equivalent CO 2 emissions (Fig. 7.10). This is because CO 2 emissions are mainly concentrated in coal mining and liquid fuel production links.

By John Sullivan, Office of Engineering Communications on Nov. 27, 2012, 9 a.m. The United States could eliminate the need for crude oil by using a combination of coal, natural gas and non-food crops to make synthetic fuel, a team of Princeton researchers has found. Besides economic and national security benefits, the plan has …

of liquid fuels will be required. Coal liquefaction is one source, and is backed by large recoverable coal reserves globally. These reserves are indeed significantly greater than for other fossil fuels.

The process of coal liquefaction creates synthetic liquid fuels from solid coalas substitutes for various petroleum products. There are two types of liquefaction – direct and indirect1. Direct liquefaction converts solid coal directly into liquid form with no intermediate step, which results in only the partial dismantling of the coal structure.
When coal (∼63% on an energy basis) and biomass are fed to a smaller CBTL- OT plant (one million tonnes of biomass (dry)/year) producing about 8,100 bbl/day liquid transportation fuel, the total plant cost is about $1.3 billion for a CO 2 venting plant and $1.4 billion for a CCS-based plant.
Simulation results showed that coal type significantly affects the volume of FT liquid fuels produced, with production ranging from 21,000bbl/day to 43,000bbl/day.

For example, Jiang and Bhattacharyya (2017) performed a techno-economic assessment of direct coal biomass to liquid plants; Zhou et al. (2017) used life cycle assessment to analyze energy consumption, greenhouse gas emissions, cost, and local employment effects of liquid fuel production from oil shale, coal, and biomass; …
Biomass-, coal-, gas- and waste-to-liquids (XTL) processes are slowly making inroads, but the global contribution from these sources to liquid transport fuel production is still <5 %. The current global demand for crude oil is around 5.2×10 9 m 3 ·a −1, which is equivalent to 90 million barrels per day (bpd) [1] .
CTL or coal liquefaction technology can convert coal to synthetic fuels, which are refined into gasoline and diesel fuel. Conventional coalbed gas, which is expelled, trapped, and …

Because the coal is first gasified before conversion to liquid fuels, the Fischer-Tropsch (F-T) process for CTL is known as a type of indirect coal liquefaction (ICL). ICL is a completely different approach from DCL for providing liquid fuels from coal. ICL
Coal liquids from gasification followed by F-T synthesis are of such high quality that they do not need to be refined. Coal liquefaction is believed capable of providing clean substitute fuels at between $35 and $45 per barrel (Gray et al ... The world's liquid fuel production reached approximately 15.6 million m 3 per day (98.05 million BPD ...
CTL or coal liquefaction technology can convert coal to synthetic fuels, which are refined into gasoline and diesel fuel. Conventional coalbed gas, which is expelled, trapped, and sealed commonly occur in sandstone reservoirs in coal-bearing sequences. ... It was not until 1923, though, that the production of liquid hydrocarbons from coal ...
Diesel fuel is the common term for the distillate fuel oil sold for use in motor vehicles that use the compression ignition engine named for its inventor, German engineer Rudolf Diesel. He patented his original design in 1892. Diesel fuel is refined from crude oil and from biomass materials. One of the fuels that Rudolf Diesel originally ...
the liquid fuels or/and valuable chemicals. The CEC has the potential to outperform coal gasification, Fischer-Tropsch synthesis, and direct coal gasification because: 1. It does not require high temperatures and pressures; 2. The hydrogen generated is completely clean and inexpensive (under $3 per kg); 3. The solid.
Today, CO 2 emissions are spread fairly equally between coal, oil, and gas. In contrast, Latin America and the Caribbean's emissions have historically been and remain a product of liquid fuel—even in the early stages of development coal consumption was small. 1. Asia's energy remains dominant in solid fuel consumption and has notably ...

The EIA projects a steady rise in coal consumption to 1.56 billion short tons by 2030, including 29 million short tons for coal-derived liquid fuels production.
Through established coal-to-liquids (CTL) processes, America's supply of coal can be transformed into liquid fuels which include high-grade diesel and jet fuels. CTL technology has a 60-year history of success, and CTL with carbon dioxide capture and storage (CCS), produces cleaner fuels with greenhouse gas emissions comparable to those from ...

2.2.2.4.2 Coal-to-liquid (CtL) CtL as an alternative fuel to diesel is considered to be one of the technology options to reduce petroleum consumption in on-road transportation. The CtL technology includes coal pyrolysis technology, direct coal liquefaction technology, and indirect coal liquefaction technology (F-T synthesis).
4 Liquefaction. Coal liquefaction is the process of making a liquid fuel from coal. The fundamental difference between coal, a solid, and liquid fuels is that the liquid fuels have a higher hydrogen:carbon ratio. Liquid fuels have lower ash contents and are easier to upgrade (i.e., to remove unwanted impurities such as nitrogen and sulfur).
Figure 8: Comparison between gasoline and liquid coal-based fuel [34] Researchers have introduced an alternative way of using coal to address these issues to produce synfuel, known as coal-biomass to liquid or CBTL process. One of the main concerns regarding the CTL process is that the production process causes carbon …
