Bituminous coal consists principally of condensed ring structures containing aromatic and hydroaromatic rings. The condensed units are connected mainly by short aliphatic chains and ether linkages. Coal liquefaction reactions in the usual temperature range...

Of course, if the plant is at the exit of the mine, with coal at 20$ per tonne, only 8 dollars per barrel are needed for coal purchase. All included, turning coal to liquid becomes competitive for someone who buys coal on the international market (@100 dollars per tonne), without capture and sequestration, when oil is over 100 dollars per ...

Coal-to-liquid (CTL) technology produces fuels, such as gasoline and diesel from coal and is a feasible solution to the oil shortage (Liu et al., 2016). China's energy resource is characterized by "rich coal, less gas, lack of oil" ( Li and Hu, 2017 ); the proved energy reserves comprise 94% coal, 5% oil, and only 0.6% gas ( Han et al., 2018 ).

In the second step, the syngas is further synthesized into liquid fuel. Coal is the most abundant energy reserve in the world. According to statistics of the International Energy Agency (IEA), of the top 10 coal producers in 2011, China has the highest coal production – 3576 metric tons (Mt) (46%), whereas the United States produces 1004 Mt ...

Wind and solar are not only meeting Chile's growing demand; they are also starting to replace coal power, as momentum builds for Chile's coal phase-out. In mid-2019, the Chilean Government announced a plan to phase out coal generation by 2040. Ahead of COP26 in 2021, Chile co-led the launch of the No New Coal Power Compact.

The coal-to-liquid (CTL) technology is a strategic response to the shortage of oil and gas resources in China and a guarantee for national energy security. Thanks to heavy investment in CTL research and development, China Energy has realized localized, clean and efficient coal conversion. The company now operates the world's biggest …

Four coal-to-liquid (CTL) routes, called direct coal liquefaction (DCL), indirect coal liquefaction (ICL), coal-based methanol to gasoline (CBMTG), and coal tar hydrogenation (CTH), has been fully industrialized in China to relieve the excessive dependence on external oil. ...

Coal has been mined and used as a source of energy for centuries. The first recorded use of coal was in China, with indications that the Chinese began using coal for heating and smelting about 2,500 years ago, and most historians believe that coal was used in various parts of the world 3,000–4,000 years ago during the Bronze Age [].A system for mining …

the product. The chain from unexploited coal-to-liquid hydrocarbon product is divided into four processes: coal mining, coal washing and selection, coal transport and coal-to-liquid hydrocarbon production. Lacking data on the manufacturing and decommissioning of vari-ous equipment and plants, they are not included in the life cycle of this ...

Indiana Center for Coal Technology Research 4 CCTR COAL CONTENTS Volatile matter consists of aliphatic carbon atoms (linked in open chains) or aromatic hydrocarbons (one or more six-carbon rings characteristic of benzene series) and mineral matter

Conversion of coal to liquid requires an increase in the hydrogen-to-carbon ratio of coal, which can be achieved either by direct or indirect liquefaction. Direct liquefaction adds gaseous hydrogen to slurry of pulverized coal- and recycled coal-derived liquids in the presence of catalysts. The process is efficient, but further refining is ...

The coal-to-liquid coupled with carbon capture, utilization, and storage technology has the potential to reduce CO_2 emissions, but its carbon footprint and cost assessment are still insufficient.

Aquatech, a global leader in water purification technology for industrial and infrastructure markets, has been awarded a contract to provide a water treatment facility that includes a Zero Liquid Discharge (ZLD) plant for a coal to liquid fuels conversion project being developed by Shenhua Ningxia Coal Industry Co. Ltd., a division of Shenhua Group, …

Amid all the attention to the converging of three energy-related 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 ...

Continued reliance on oil is unsustainable and this has resulted in interest in alternative fuels. Coal‐to‐liquids (CTL) can supply liquid fuels and have been successfully used in several cases, particularly in South Africa. This article reviews CTL theory and technology. Understanding the fundamental aspects of coal liquefaction technologies is …

Increased demand for liquid transportation fuels coupled with gradual depletion of oil reserves and volatile petroleum prices have recently renewed interest in coal-to-liquids (CTL) technologies. Large …

zones. As a consequence, liquid products as high as 35 percent by weight of the coal have been reported by chis process. The hydrocarbon gas yield is thus low, at about 7 percent by weight of the coal. Although a higher liquid yield is obtained, the total net conversion is still around 40 to 45 percent by weight

In this study, the life cycle assessment method was used to evaluate energy and material consumption and pollutant emission based on the 2013 ledger data of a coal chemistry factory in western China and the subprocesses used include coal gasification, conversion, purification, Fischer–Tropsch synthesis and liquid hydrocarbons separation. …

Throughout the world domestic coal is now once again gaining in importance. Starting with the fossil fuel, coal - especially coal of a low quality, i.e. with a high ash or sulphur content - can be subjected to a number of process steps to obtain a variety of end products, such as fuels, chemicals and even electricity. In this respect, IGCCs, which are purely coal-fired …

Biomass-to-liquids is a subprocess of the more generic XtL processes, where X is any carbon source. Coal-to-liquids (CtL) and gas-to-liquids (GtL) have been developed industrially since 1925 and can be considered mature technology, though there are still developments going on. Several natural gas-to-liquid plants have been built in Qatar, …
