How Responsive Are EU Coal-Burning Plants to Changes in Energy Prices? [PDF]
, 2015 The European Union (EU) Emissions Trading System (ETS) has implicitly made it more expensive to burn coal relative to natural gas because coal has a higher carbon content.

Advanced Functional Materials, EarlyView.A pore tuning strategy to amplify the multi‐site MOF‐SO2 interactions is proposed to achieve an enhanced trace SO2 capture and chemiresistive sensing in highly stable isostructural DMOFs by annelating benzene rings. This work provides a facile strategy to achieve tailor‐made stable MOF materials for specific multifunctional applications.

The effect of hard coal density on its flotation performance [PDF]
Acta Montanistica Slovaca, 2005 Hard coal flotation depends on many factors, one of which is the density of the grains floated. The heavier the grain, the greater the gravitational force that counteracts the force of adhesion between the grain and an air bubble, and the lower the ...

Using geophysical density logging to estimate the thickness and density of coal seams in the Southern region of Brazil [PDF]
REM: International Engineering JournalThis study shows the usefulness of borehole geophysical logging of density in the identification of coal seams, in relation to other lithologies present in a coal deposit located in the south of Brazil. Four drillholes were studied.

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Tools available for methane recovery from mines belonging to C.E.H. Petroşani [PDF]
MATEC Web of ConferencesMine gas is present both in coals and in the surrounding rocks and basically consists of methane (some-times almost 100%) mixed with carbon dioxide (up to 5%) with nitrogen (a few percent) and traces of carbon monoxide.

A novel dry coal feeding concept for high-pressure gasifiers [PDF]
, 1977 A novel dry coal feeding concept was developed for injecting ground coal into high-pressure gasifiers. Significant power savings are projected because the coal is injected directly with a ram and there is no requirement for pumping large volumes of gas ...

The mechanism of char ignition in fluidized bed combustors [PDF]
, 1987 Knowledge about ignition processes of coal in fluidized beds is of importance for the start-up and dynamic control of these combustors. Initial experiments in a transparent fluidized bed scale model showed the existence of a considerable induction period
