Coal is the most abundant energy and hydrocarbon resource in the United States which has
been primarily used for power generation. With the increasing retirement of coal power …

Biosolids (stabilised sewage sludge) are solid residuals from the wastewater treatment
process and are considered important bioresource. Therefore, the valorisation routes of …

Coal is the world's most abundant energy source because of its abundance and relatively
low cost. Due to the scarcity in the supply of high-grade coal, it is necessary to use low …

Limited availability and large industrial demands of high-grade coals have forced many coal-
dependent industries to shift their preference towards low-grade coals to meet the feedstock …

Methyl orange is an anionic water-soluble carcinogenic azo dye. Excessive dye
concentration in water is a major health concern worldwide. In this current study …

This paper used sodium hydroxide to improve the CO 2 adsorption capacity of coal-based
activated carbon. The effect of several modification parameters, including sodium hydroxide …

Physicochemical structure characteristics and its effects on the heat of gas adsorption are
the foundation for coalbed methane (CBM) development. Herein, this paper selected …

Chemical leaching is one of the most efficient methods for improving low-grade coal due to
its ability to remove both inorganic and organic minerals economically. This study examined …

Coal fly ash (CFA), an industrial by-product of high-temperature combustion of coal in coal-
fired power plants, is one of the most complex and largest amounts of industrial solid wastes …

The current research was investigated the mechanism of coal demineralization and the
effect of leaching parameters on high ash coal and study the characterization of pre and post …
