The chemical desulfurization of two high-sulfur Illinois Basin coals (Illinois No. 6 and Indiana No. 5) was investigated using selective oxidation with a mixture of hydrogen peroxide in acetic acid, which is known to produce peroxyacetic acid in situ.The simultaneous removal of both inorganic and organic sulfur was measured with respect to coal type, particle size, method of coal preparation ...
Coal gasification is the process of producing syngas–a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), methane (CH 4), and water vapour (H 2 O)–from coal and water, air and/or oxygen.
The spill that tainted the water supply involved a chemical used in coal processing. But it didn't involve a coal mine - and that's a point state officials are trying to convey to the public.
Chemicals used in mining and processing minerals contaminate the land, water, and air, causing health problems for workers and people living near mines.
"However, these chemicals are considered hazardous and are covered by MSHA's Hazard Communication standards." On April 9, MSHA issued a health hazard alert in response to the coal processing chemical spills earlier this year. The alert reminded operators that miners and plant employees must be provided information on the chemicals they're ...
Coal tar is a dark viscous material obtained as a by-product during the process of destructive distillation of coal (to produce coke oven gas and coke). Coal when heated to 1050 o C, coke oven gas is liberated; it contains valuable chemical compounds.

Iron based chemical looping process for direct coal gasification—coal direct chemical looping (CDCL) processUnlike the SCL process which employs a conventional gasification system to generate syngas feedstock, the iron based coal direct chemical looping (CDCL) process takes coal directly as feedstock rather than syngas.
11.10 Coal Cleaning 11.10.1 Process Description1-2,9 Coal cleaning is a process by which impurities such as sulfur, ash, and rock are removed from coal to upgrade its value. Coal cleaning processes are categorized as either physical cleaning or chemical cleaning. Physical coal cleaning processes, the mechanical separation of coal from its
Putman Media's Influential Women in Manufacturing program launched this year. We received nearly 100 nominations for women with varying titles across many industries. As part of the coverage, Chemical Processing is profiling winners in the chemical industry to learn more about their trials and triumphs.

This paper briefly reviews the present state of the art for the chemical removal of sulfur from coal via an oxidation process. A brief summary of the existing sulfur removal processes and their economics along with the chemistry and kinetics of inorganic and organic sulfur removal from coal and the reactor design considerations are outlined.
Technology The coal-to-gasoline & coal-to-nitrogenous fertilizer processes. TransGas develops projects that use well-proven clean coal gasification technology, chemical transformation of coal into nitrogenous fertilizer, liquid fuels and industrial gases. Our projects do not use traditional combustion or coal …
The abundance of coal combined with lack of natural gas resources in China is strong inducement for the coal to chemicals industry pursued there. Similarly, has built and operated coal-to-chemicals facilities in South Africa. Coal to chemical processes require substantial quantities of water.
Chemicals from Coal. For centuries, people have been making useful products by performing chemical reactions with natural substances — everything from manufacturing glass from sand to converting wood to methanol, acetic acid, and charcoal.
coal processing In coal utilization: Carbonization (coke making) Coke is the solid carbonaceous residue that remains after certain types of coal are heated to a high temperature out of contact with air.
Processing the Coal After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal.
Alibaba.com offers 752 chemicals used in coal mining products. About 36% of these are crusher, 5% are conveyors, and 5% are rubber belts. A wide variety of chemicals used in coal mining options are available to you, such as hammer crusher, linear, and jaw crusher.
This week researchers at Ohio State University announced a milestone in the development of a far cleaner way to use the energy in coal—a process called chemical looping that has the potential to ...
China's Coal to Olefins Industry Date 2 July 2014 Asia China Energy Chemicals F.I.T.T. for investors Coal, to Syngas, to Methanol, to Olefins Only in China Converting China's coal into olefins (ethylene and propylene) is a multi-step, multi-industry process. Coal is first converted to syngas; syngas is then converted to methanol; methanol is
The refuse showed 14.0% combined elements as in the coal (i.e. C, H, O, N, S) and the remainder being ash. It may be assumed that these combined elements occur in the same proportions as they do in the coal. Estimate the amount of amount of flue-gas (dry basis), amount of water coming out of the process, and the %excess air.
China Beijing International Coal Chemical Industry Exhibition will take place in Beijing, China for three consecutive days. The primary objective of this international trade show is to make the coal chemical industry aware of the latest and advanced techniques …
