Anthracite
The proportion of ammonia to ammonium in water is mainly depending on the pH and temperature. As one of the most hard-to-treat pollutants, its adsorption by rocks/soils was rarely investigated in the literature. Experimental investigation of ammonia adsorption by lignite and clay has been carried out by Humenick and Mattox (1978). Actual ...
Anthracite
Anthracite generally costs two to six times as much as regular coal. In June 2008, the wholesale cost of anthracite was US$150/short ton, [19] falling to $107/ton in 2021; it makes up 1% of U.S. coal production. [20] The principal use of anthracite today is for a domestic fuel in either hand-fired stoves or automatic stoker furnaces.
Introduction to Ammonia Production
However, the use of ammonia in these two products represents only a small fraction of the total global ammonia production, which was around 176 million metric tons in 2014 (I). To appreciate where the industry and technology are today, let's first take a look at how we got here. Ammonia has been known for more than 200 years.

Executive Summary – Ammonia Technology Roadmap
Ammonia production currently relies heavily on fossil fuels. Global ammonia production today accounts for around 2% (8.6 EJ) of total final energy consumption. Around 40% of this energy input is consumed as feedstock – the raw material inputs that supply a proportion of the hydrogen in the final ammonia product – with the rest consumed as ...
