Pyrolysis of low rank Canadian coals
Abstract A bench scale fluidized bed reactor with a continuous feed rate of 15–30 g/h has been developed to study the flash pyrolysis of coal at atmospheric pressure. The pyrolysis behaviour of four low rank Canadian coals has been investigated at 0.44 s apparent vapour residence time over a temperature range of 500–800°C.

Oxidation Mechanism of Low Rank Coal
In order to elucidate the chemical structure of the parts which are destroyed in the transition from low rank coal to humic acid, chemical and infra-red spectroscopic examination of the solid products obtained byHNO3-oxidationn and wet O2-oxidation of coals were tried and also their reactioncharacteristics were compared with those of various model ...

Ga–O–Pt Electronic Bridges Bypass Single‐Site Constraints for pH‐Universal Hydrogen Evolution
Well‐defined oxygen‐bridged Ga–O–Pt catalysts are constructed for pH‐universal hydrogen evolution, highlighting the relationship between oxygen‐bridged electronic coupling, rapid surface hydrogen redistribution, and superior catalytic performance. ABSTRACT Single‐site descriptors often fail to capture hydrogen evolution on heterometallic interfaces ...

Task 27 -- Alaskan low-rank coal-water fuel demonstration project [PDF]
Development of coal-water-fuel (CWF) technology has to-date been predicated on the use of high-rank bituminous coal only, and until now the high inherent moisture content of low-rank coal has precluded its use for CWF production.
