Coal is an important fossil fuel, a resource primarily used for electric power generation, and
currently supplies 41% of global electricity needs. Fossil fuel is one of the demanding …

Coking wastewater is used to prepare coal slurry, which can be used as combustion and
gasification fuel. This promising technology simultaneously achieves resource utilization …

This work reports the synthesis and performance of a novel dispersant for coal water slurry
(CWS). The dispersant is derived from humic acid (HA) and has a topological structure …

Changing wettability of coal rock surface for enhanced gas recovery, surfactant is widely
used in coalbed methane exploitation. Recently, soybean phospholipid as non-toxic and …

It is a significant subject that low quality coals could be used for high concentration slurry
preparation because of the large reserve and low price. Nevertheless, due to the …

The side chain structures of polycarboxylates are of great importance for their dispersion
performance. The impacts of side chain length (length of polyethyleneglycol PEG, m ranging …

The adsorption conformations of random-structure polycarboxylic acid (PC R) and block-
structure polycarboxylic acid (PC B) on coal surfaces were analyzed from a microscopic …

The purpose of this study is a comparative analysis of droplet burnout rates of coal-water
slurries with typical composition (based on coal dust) and new compositions of waste …

The aim of this work is to study the slurryability of two low-rank coals (a Chinese YX lignite
and a Chinese ZD sub-bituminous coal) and various upgraded coals or chars obtained by …

To improve cold gas efficiency of entrained-flow gasification, coal water slurry (CWS) as a
fuel must have high heating value at low viscosity. Especially, considering unstable supply …
