Biosolubilization of Polish brown coal by Gordonia

2015-3-1  The biosolubilization of nitric acid-pretreated brown coal (58.7 and 51.5% for G. alkanivorans S7 and B. mycoides NS1020, respectively) occurred much faster than the conversion of crude coal and within the first 3 days was around two-fold higher . During the subsequent period, biosolubilization continued and reached values of 86.0 and 88.7% on

Improvement of efficiency of brown coal

2018-8-22  Clean coal technologies (e.g. coal biosolubilization) are of essential value, especially in Europe, where coal is the national wealth and other energy sources like crude oil are not available. Fusarium oxysporum LOCK 1134, the strain isolated from brown coal, efficiently biosolubilizes lignite. The obtained liquefied products contain 50% less sulfur and over 99% less mercury than the crude coal.

brown coal) is a sedimentary rock with a brown coal content, producing a calorific value of from 3350 kJ kg-1 to 4200 kJ kg-1 at a maximum ash content of 26-29% at 50% moisure content. Smut coals are mined separately, and then mixed with brown coal in appropriate proportion to get a mixture with parameters of boundary fuel for a certain type of

Fungal biosolubilization of Rhenish brown coal

1999-7-1  Residues and coal fractions that remained after the biosolubilization of Rhenish brown coal by strains of Lentinula edodes and Trametes versicolor have been studied by Curie-point pyrolysis/gas chromatography/mass spectrometry using tetraethylammonium hydroxide (NEt4OH) at 610 °C. To differentiate methyl derivatives of esters and ethers from free or bound hydroxyl and carboxyl groups

Brown coal coal classification Britannica

Brown coal, broad and variable group of low-rank coals characterized by their brownish coloration and high (greater than 50 percent) moisture content. These coals typically include lignite and some subbituminous coals.In Great Britain and other countries, the term brown coal is used to describe those low-rank coals (lignite and subbituminous coal) that generally have a brown colour.

Coal is a hydrophobic, highly porous and heterogeneous sedimentary rock mined for its energy content. It is classified according to the degree of aromaticity and ranked as either lignite, (sub)-bituminous coal or anthracite [1,2].Physically, it is a material with a hardness scale of up to 3 Mohs for anthracite and classified as naturally recalcitrant [3,4].
