Climate change is expected with the ever rising human population on the planet earth. The
different anthropogenic activities have resulted in increased levels of greenhouse gases …

The generation mechanism of light tar during Shenfu bituminous coal pyrolysis was
investigated in this work. TGA, Py-GC/MS, TGA-FTIR and reactive force field simulations …

The coal water slurry gasification combined with ammonia synthesis process produces
various complex wastewaters that are difficult to handle, and the improper disposal of these …

In this paper, the impact of the programmable heating and quenching (PHQ) method on coal
pyrolysis tar yield was investigated via ReaxFF molecular dynamics method. Firstly …

This paper investigates the pyrolysis of outer sheath polymer of a PVCsingle bondCaCO 3
based cable. TG-DSC-MS, temperature-dependent FTIR, XRD and XPS experiments were …

Carbide slag may pollute the environment because it is difficult to handle. In this paper,
carbide slag without pretreatment served as the new source of calcium and was added to …

Revealing the pyrolysis reaction pathway related to coal structure evolution under different
temperatures is important for the industry to design reactors and process operations. In this …

Coal pyrolysis and volatiles upgrading were intelligently coupled into an integrated reactor
with two sections that enabled tar quality to be improved. The upper drop tube served as the …

Complete removal of tar from wastewater is one of the most challenging problems in the
pyrolysis of low–rank coal. In this study, the properties and composition of tar are …

Unsatisfactory inlet structure of a downer can directly lead to uneven gas–solid distribution,
poor mixing effect, insufficient heat transfer, and affect the coal pyrolysis efficiency. In …
