Pubmed And Lignite

The Greek peaty lignite of the Megalopolis Basin was used as raw material for obtaining both fly ash and humates. Retention was studied at 291, 308, 323, 338, and 353 K and at several pH values. The adsorption capacity was found to increase at neutral pH and, also, with raise of temperature, that is, from 760 to 1300 mg humicsg fly ash at 291 ...

The preparation of synthetic graphite materials with ...

Lignite, obtained from Inner Mongolia of China, was used as the starting precursor for the preparation of synthetic graphite materials. The raw coal was ground to powder and then sieved into a particle size of less than 74 m. Lignite powder LC, H 2 SO 4 and H 3 PO 4 were proportionally mixed LC g H 2 SO 4 mL H 3 PO 4 mL 1 0.1 5 ...

Production of Polyhydroxyalkanoates Using

Polyhydroxyalkanoates PHAs are bacterial polyesters which are considered biodegradable alternatives to petrochemical plastics. PHAs have a wide range of potential applications, however, the production cost of this bioplastic is several times higher. A major percentage of the final cost is represented by the price of the carbon source used in the fermentation.

The Impact of Predried Lignite Cofiring With Hard

Tests on the boiler were performed during low load operation and the lignite share reached over to 36 by mass. The predried lignite, kept in dedicated separate bunkers, was mixed with bituminous coal just before the coal mills. Computational fluid dynamic CFD simulation of a cofiring scenario of lignite with hard coal was also performed.

Hydrothermal Synthesis of Ultra-Light Coal-Based

A novel carboxymethyl cellulose CMC-supported graphene oxide aerogel CGOA was fabricated from a cost-effective and abundant bituminous coal by a mild hydrothermal process and freeze-drying treatment. Such an aerogel has cross-linked graphene oxide layers supported by CMC, and therefore, displays high mechanical strength while having ultra-low density 8.257 mgmiddotcmminus3.

Frontiers | Research on a Mixed Culture Technique of

White rot fungi mixed culture technology was applied in order to improve the efficiency of lignite liquefaction. In this paper, 15 fungi were used to liquefy Zhaotong lignite. The results showed that there was a good linear relationship between the liquefaction effect and lignin peroxidase LiP. Since the low activity of LiP is the barrier in real practice, five strains with the highest LiP ...

Selective oxidation of lignite to carboxyl chemicals

Selective oxidation of lignite to carboxyl chemicals is an important way for the utilization of lignite in a clean and efficient manner. At present, the methods of lignite oxidation to carboxyl chemicals include nitric acid oxidation, sodium hypochlorite ...

Effects of hydrothermal dewatering of lignite on

INTRODUCTION. Lignite, a low rank coal, attracts increasing attention from researchers with the increase of demand on coal resources worldwide. 1 Coal water slurry CWS made with lignite is preferred during the storage and transportation of lignite to prevent its spontaneous combustion. 2, 3 However, lignite contains high moisture e.g. 30 that consumes extra thermal energy to burn in the ...

Microbial life in deep subseafloor coal beds | PNAS

Deep beneath the seafloor, microbial communities thrive on the leftovers of organic material that in the past settled down from the surface layers of the ocean to the sediment. As the organic matter was buried deeper and deeper over geological time it became increasingly recalcitrant to microbial degradation. Microbial cells that still persist in these ancient deposits appear to survive at the ...

The iron-oxidizing proteobacteria | Microbiology Society

The iron bacteria are a collection of morphologically and phylogenetically heterogeneous prokaryotes. They include some of the first micro-organisms to be observed and described, and continue to be the subject of a considerable body of fundamental and applied microbiological research. While species of iron-oxidizing bacteria can be found in many different phyla, most are affiliated with ...

The objective of this research was to evaluate, in saline-sodic soils, the effect of the application of a low rank coal LRC, lignite type, along with an inoculation of bacteria that release humified organic matter HOM from this type of coal. The soil microbial activity and related coal biosolubilization enzymes mediated by microorganisms were determined along with the chemical variables ...

Methane production from coal by a single

Methane associated with coal beds is an important global resource of natural gas. Much of the methane in coal comes from microbial methanogenesis. Mayumi et al. characterized a strain of Methermicoccus shengliensis that, unexpectedly, is capable of making methane from the dozens of methoxylated aromatic compounds found in a variety of coal types see the Perspective by Welte.
