The Chemistry of the Coal-Tar Colours [PDF]

Nature, 1886
THIS is an excellent little practical manual dealing with a subject of great scientific and industrial importance—a subject the scientific side of which has been somewhat neglected in this country, to the inevitable detriment of the industrial side. The decline of this industry in England is a tempting subject to expatiate on; but the moral has of late

Study on the Mining Pressure Law of Tunneling Roadway in Coal Pillar of Lower Coal Seam in the Mining Hollow Area

Energy Science &Engineering, EarlyView.
ABSTRACT In the downward mining, the goaf of the upper coal seam and the remaining coal pillars will have a negative impact on the stability of the lower coal seam roadway. If the roadway is excavated in the lower coal seam coal pillar, it is more likely to produce mutual superposition effects, which greatly increases the difficulty of roadway ...

Pyrolysis characteristics and product distribution of low-rank coal with heat-carrying particles adopting TG-FTIR and a novel self-mixing down tube reactor

Case Studies in Thermal Engineering
A novel self-mixing down tube (SDT) pyrolyzer has been developed, which can separate the heat carrying particles preheated in the fluidized bed from the coal, and the two can be mixed through a specific structure to instantly heat the coal particles to a

The Influence of Solid Heat Carrier Load of Char on Pyrolysis Characteristics of Pulverized Coal in a Fluidized Bed Reactor

Energies
Pulverized coal pyrolysis based on solid heat carrier has a huge advantage in high tar yield. In this study, pyrolysis experiments on pulverized coal were conducted in a lab-scale fluidized bed reactor at 650 °C, utilizing char as the solid heat carrier.
