Dual‐Function Electrocatalysis: Simultaneous Wastewater Remediation and Hydrogen Evolution—A Comprehensive Review

Carbon Energy, EarlyView.
Replacing the oxygen evolution reaction with the electro‐oxidation of pollutants and waste streams offers an energy‐efficient route for simultaneous hydrogen production and pollutant remediation. This review summarizes the reaction mechanisms, catalyst design principles, and emerging paired‐electrolysis strategies that govern activity, selectivity ...

Interfacial Electronic Coupling in the GeSe2/Volcanic‐Rock–Like Carbon Framework Activates Reversible Intermediate Conversion for High‐Rate Sodium Storage

Carbon Energy, EarlyView.
A combined sol–gel/solid‐state approach was developed to integrate GeSe2 with a “volcanic‐rock”–like carbon framework (C). C incorporation reactivates the otherwise irreversible intermediates Na2Ge2Se5 and Na2GeSe3, thereby suppressing irreversible Na+ consumption.

Challenges of Bio‐Syngas Conversion to High‐Value‐Added Liquid Chemicals and Fuels via COx Hydrogenation

Carbon Energy, EarlyView.
Converting biomass‐derived syngas into value‐added fuels and chemicals offers a promising route toward carbon neutrality, yet unfavorable H2/COx ratios, elevated CO2 levels, and trace impurities pose persistent obstacles. This review examines strategies spanning syngas conditioning, impurity‐tolerant catalyst development, and integrated process design,

Constructing Biomass‐Derived Ultra‐Thin 2D Carbon Nanoweb via Confinement‐Driven Bubbling Effect for High‐Rate Zinc‐Ion Storage in Hybrid Capacitors

Carbon Energy, EarlyView.
A confinement‐derived bubbling effect strategy is used for controllable synthesis of biomass‐derived 2D carbon nanoweb with ultra‐thin longitudinal dimensions (1.5−2.5 nm) and high surface area (2055 m2 g−1). Its ultra‐thin 2D nanoweb structure enhances rate capability and cycling stability at high charge–discharge rates and in high‐mass‐loading ...

Design of Coal Preparation Plants: Problems and Solutions

2016
With the increase of coal production, the requirements to its quality are also increasing. Improvement of coal quality is only possible with the use of coal preparation methods. The main objective is to achieve 100% treatment volume of the mined coal. In recent years, only in the Kuznetsk Basin 15 coal preparation plants have been built.

Simulation of coal preparation plants

SIMULATION, 1986
Coal preparation is a process for removing physical impurities from coal. The process is carried out in large plants whose capa cities range from 500 to 20,000 tons of coal per day. There are about 500 such plants within the United States. A coal preparation plant simulator was developed under the sponsorship of the U.S. Department of

Survey of noise in coal preparation plants

The Journal of the Acoustical Society of America, 2007
In response to the continuing problem of noise induced hearing loss (NIHL) among mine workers, the National Institute for Occupational Safety and Health (NIOSH) has conducted numerous noise surveys in coal preparation plants. The research, consisting of worker dose monitoring, task observations, and equipment noise profiling, was completed in eight ...
