Abstract: This thesis deals with various physical-chemical aspects of agricultural and environmental applications of the South Moravian lignite. The main attention was paid to the behavior of lignite in an aqueous environment and the application potential of lignite as a cheap, effective and universal sorbent.
In addition to the environmental benefits of reduced NH losses, the value of retained N nutrient in the lignite treated manure is more than $37 AUD head −1−1, based on the current fertiliser cost and estimated cost of lignite application. We show that lignite application is a cost-effective method to reduce NH loss from cattle feedlots.

Lignin is a highly abundant bio-polymeric material that constitutes cellulose one of major component in cell wall of woody plants. Alternatively, large quantity of lignin is yearly available from numerous pulping and paper industries; this is the key point that justifies its large use for industrial applications. Lignin could be one of the most essential …
We compared the impact of lignite addition on gaseous emissions during the composting of cattle manure. Adding lignite reduced N losses by 54% over the 87-day composting process, but increased CH 4 and N 2 O emissions (due to anaerobic conditions), as well as CO 2 emissions (due to additions of labile C). Total GHG …

The second major challenge in the development of coal-based CLG is the low hydrogen content of syngas. Even though the water content of lignite lies within the range of 10–50 wt%, the hydrogen content in the syngas prepared using lignite gasification without the addition of other hydrogen sources is still low [29].
The Popular Applications of Lignite Include Electricity Generation (79%) Synthetic Natural Gas Production (13%) Production of Fertilizers (7%) Home Heating and …

The extraction of humic acids from lignite has become a promising research field, owing to their fertilization potential. However, the extraction process is accompanied by the formation of lignite-based wastes (LBW). In this study, we investigated the potential of LBW, as an organic amendment, to improve the quality and productivity of degraded …
Using lignite, a low-rank coal, as a filter aid to improve dewatering of a digested sewage sludge, Thapa et al. [15] correlated the improved sludge dewaterability with filter cake properties by quantitatively analysing the cake porosity, permeability and resistance to compression as measured by the cake yield stress.
The use of lignite results in two major changes compared to BAU – a 4.9 kg reduction of NH 3 emission and 28–34 kg increase of CO 2 emission per cattle per year at 3 kg m −2 of lignite; or 8.2 kg reduction of NH 3 emission and 41–51 kg increase of CO 2 emission per cattle per year at 6 kg m −2 of lignite (Fig. 2).
The effective use of lignite in the gasification process requires a number of analyses (Higman et al. 2008). Basic technological analyses are increasingly being accompanied by petrographic analysis. They allow predicting the technological properties and the applications of lignite in a relatively short time (Bielowicz 2012). One of the …
lignite, then deresined wax is acquired by cooling the extracted solvent toluene, last refined wax called S wax could be made after a series oxidation process, which can be used as basic raw materials for production of more valuable synthetic wax. Montan wax have a wide range of applications in industry,in agriculture, and in forestry. But there

Lignite as an extremely low-cost low-rank coal (about 300 RMB per ton) has low aromaticity, which would result in high disordered microstructure and wrinkled carbon layers after carbonized under inert atmosphere . Most importantly, it is a low-cost and high-carbon-yield hard carbon precursor, which can satisfy the large-scale application.
Lignite is crumbly and has high moisture content, which contributes to its low heating value. Lignite accounted for 8% of total U.S. coal production in 2021. About 56% was mined in North Dakota and about 36% was mined in Texas. The other 8% was produced in Louisiana, Mississippi, and Montana. Lignite is mostly used to generate electricity.
