Experimental study on effect of H2S aqueous solution on permeability of low-rank coal

, 2021
In order to study the effect of H2S solution to the permeability of low-rank coal, we select low-rank coal sample from Wucaiwan Coal Mine（ＷＣＷ） of eastern Junggar Basin coalfield and Shaerhu Coal Mine（ＳＥＨ） of Tuha coalfield.

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.

Improving bubble-particle attachment during the flotation of low rank coal by surface modification

International Journal of Mining Science and Technology, 2020
Based on the problems caused by many oxygen-containing functional groups and poor floatability on the surface of low rank coal, the characteristics of low rank coal were analyzed systematically by means of scanning electron microscopy (SEM), X-ray ...

Chitin‐Derived Carbon‐Metal Functional Materials

Advanced Functional Materials, EarlyView.
Functional carbon materials are synthesized from combination of biopolymer (chitin) and iron precursors. The resultant material exhibits superior surface area and adsorptive properties compared to carbon materials synthesized directly from pure chitin.

Kinetics‐Controlled Architecture of Binder‐Free Organic Electrodes for Enhanced Ion Transport

Advanced Functional Materials, EarlyView.
Pulse reverse electrodeposition controls nucleation and growth to create hierarchically porous Py‐derived oligomeric electrodes with enhanced ionic accessibility and reduced transport resistance. The resulting binder‐free architectures translate these transport advantages into practical sodium‐storage functionality.

Oxidation Mechanism of Low Rank Coal

Journal of the Fuel Society of Japan, 1965
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 ...

Pyrolysis of low rank Canadian coals

Fuel Processing Technology, 1986
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.

Dimensionality‐Driven Interfacial Electronic Coupling in Carbon‐Supported Gd‐CuO Catalysts for Selective CO2 Electroreduction to Ethylene

Advanced Functional Materials, EarlyView.
The 2D carbon‐supported Gd–CuO exhibits strong interfacial electronic coupling, abundant oxygen vacancies, and highly exposed active sites, enabling efficient CO enrichment and C─C coupling toward selective and durable CO2‐to‐C2H4 conversion. ABSTRACT Copper‐based catalysts are promising for electrochemical CO2 reduction toward value‐added chemicals ...
