In the past, on the lignite hydrogen business in the Victorian Government, Japan and Australia have been jointly conducting the marine transportation of lignite gasification toward Japan by New Energy and Industrial Technology Development Organization (NEDO) and Japanese companies.

Removal of Pb 2+, Cu 2+, Cd 2+, and Zn 2+ ions from their multi-component aqueous mixture by sorption on natural lignite was investigated. Sorption kinetics, dependence of sorbed amount on pH, initial concentration of metal ions, and on temperature, effect of electrolytes (KNO 3 and NaCl) were tested as well as desorption …

The state-owned company currently has five operational lignite mines located in Kutch, South Gujarat, and Bhavnagar region. It is purportedly the largest merchant seller of lignite in the country.

The present work is aim at modifying the HZSM-5 to further produce the BTEXN in higher yield and enhancing the deoxygenation degree of lignite-derived pyrolysis tar. Meanwhile, metal-loaded mesoporous HZSM-5 was used for enhancing the selectivity to particular target compounds during CFP of Baiyinhua lignite (BYHL).

In the 2023 fiscal year, the value of brown coal across Australia was estimated to be about 262 million Australian dollars.

Lignite, generally yellow to dark brown or rarely black coal that formed from peat at shallow depths and temperatures lower than 100 °C (212 °F). It is the first product of coalification and is intermediate between peat and subbituminous coal according to the coal classification used in the United

Abstract. Turkish lignite can be used as a new adsorption material for removing some toxic metals from aqueous solution. The adsorption of lignite (brown young coals) to remove copper (Cu 2+ ), lead (Pb 2+ ), and nickel (Ni 2+) from aqueous solutions was studied as a function of pH, contact time, metal concentration and temperature.

In 2022, production of lignite coal for Australia was 44,419 thousand short tons. Production of lignite coal of Australia fell gradually from 77,216 thousand short tons in 2003 to 44,419 thousand short tons in 2022. Lignite is the lowest rank of coal, often referred to as brown coal, used almost exclusively as fuel for steam-electric power …

This factsheet gives an overview of Germany's three active lignite mining regions, their history, and economic dependence on coal. [Update: Germany no longer world's largest lignite producer]

Direct and indirect greenhouse gas emissions from mining for green technologies need to be accurately and transparently accounted for, as highlighted by a case study of Chilean copper mining.

The results show that the catalysts have layered and mesoporous structures with tunable acidity/basicity. Catalytic ethanolysis of Xilinguole lignite was performed and the resulting ethanol-soluble portions (ESPs) were analyzed with a Fourier transform infrared spectrometer, thermogravimetric analyzer, and gas chromatograph/mass …
