A review on moisture re-adsorption of lignite treated using different drying techniques

Drying Technology, 2021
Lignite has great potential for use as one of the major sources for both energy and chemical feedstock. However, its high moisture content extremely restricts its use.

Lignite effects on NH3, N2O, CO2 and CH4 emissions during composting of manure.

Journal of Environmental Management, 2020
Production of compost from cattle manure results in ammonia (NH3) and greenhouse gas emissions, causing the loss of valuable nitrogen (N) and having negative environmental impacts. Lignite addition to cattle pens has been reported to reduce NH3 emissions

Enhanced nitrogen retention by lignite during poultry litter composting

, 2020
Composting is an effective method to transform organic wastes into soil amendments. However, significant nitrogen (N) is lost through ammonia (NH3) volatilization during composting.

Synergistic mechanism of CO2 and active functional groups during low temperature oxidation of lignite

, 2020
The rate of oxygen consumption and the release of CO2 were studied using a low-temperature oxidation simulation system. Six model compounds with different functional groups and pore structures were used in the experiment.

Lignite-Based Nitrogenous Fertilizers

Energy Sources, 1983
A sample of lignite from Elbistan was oxidized by nitric acid in two stages, using relatively dilute acid in the first stage and concentrated acid in the second stage, and then the oxidized product was ammoniated so that a coal-based fertilizer could be produced. The experiments of all the stages were designed by a 1/2 X full factorial design.
