2024年7月15日 · The purpose of this paper is to review coal-based AC production process methods, AC properties, and key variables affecting the process and product quality. Factors such as coal’s physical and chemical properties (coal type, coal rank, particle size) and process parameters, specifically activation method, temperature, and activation agents ...

American Consolidated Natural Resources manages and controls over 2 billion tons of coal reserves. Most importantly, American Consolidated Natural Resources operates among the safest underground coal mines in the world.

American Coal Council (ACC) provides relevant educational programs, market intelligence, advocacy support and peer-to-peer networking forums to advance members’ commercial and professional development interests.

2022年12月15日 · Activated carbon (AC) is an effective adsorbent in water treatment but its production method has significant emissions to the environment. This study aims to quantify the environmental impacts of various AC types and determine whether raw material selection could reduce the footprint of AC.

2023年5月10日 · Activated carbon (AC), also known as activated charcoal, is a rough, imperfectly structured kind of graphite. It has a wide spectrum of pores of varying sizes, from obvious fractures and fissures to molecular dimensions.

2023年11月20日 · Proposed a strategy of utilizing calcite in coal for high-performance AC. CaCO 3, CaO, and CaSiO 3 were formed during AC preparation by flue gas activation. Calcite in coal favors the increase of C O and π–π*. Excessive calcite in coal could result in inferior porosity topology. The enhanced mechanism of MB adsorption by calcite was proposed.

2021年5月14日 · To improve the selective catalytic reduction of NO with NH 3 over active coke (AC), coal–biomass ACs were prepared from the mixture of poplar and 1/3 coking coal for increasing the active sites. The resultant ACs were characterized by N 2 adsorption and X-ray photoelectron spectroscopy.

The fused ring structures in coal were hardly activated via cracking with K 2 C 2 O 4. However, H 2 O could oxidize some carbonaceous organics on AC-coal, introducing oxygen-containing species, further cracking of which formed pores. This was an important route for generating pore structures in AC-coal. 中文翻译：

2021年5月11日 · This chapter compiles the studies on the preparation of coal-derived activated carbon (AC) and its application for adsorption of metal ions in aqueous solutions. The general methods for preparation of coal-derived activated carbon can be divided into two categories:...

2018年1月1日 · Pore structure design is the key for achieving high-capacity and fast adsorption. Herein, we develop a simple and general method for pore regulation of coal-based activated carbons (ACs), which is based on a catalytic physical activation process by using the inherent minerals in coal precursor.
