Abstract The present work aims at studying five Indian coals and their solvent extracted clean coal products using Py-GCMS analysis correlating the characterization data theoretical principal component analysis. pyrolysis of original super were classified as mono-, di- tri-aromatics, while other prominent that obtained included cycloalkanes, n -alkanes, alkenes ranging from C 10 –C 29 . is a di...

In the steel industry, promoting use of low-grade coal is important because depletion coking coal. To compensate for lack caking property low-quality coals, binders must be added to produce coke from blends. Lignin an aromatic polymer and one main components, accounting 30% wood. The chemical structure characteristics lignin differ depending on raw woody biomass extraction method used. this stu...

Recently, the environment has indicated an increase in price of coking coal. Thus, order to produce high strength coke at a low production cost, application blending technology various types coal is required. Coal dilatation important factor determining strength. It well known that dilation values blended containing semi-soft coals does not match with weighted average value and coal; it denotes...

The switch from a carbon-based to hydrogen-based economy requires environmentally friendly methods for hydrogen production. CO 2 -reforming of methane promises be greener alternative steam-methane reforming, which accounts the majority production today. For this dry process become industrially competitive, challenges such as catalyst deactivation and degradation through coke formation must bett...

During the coking process in coal chemical industry, the stability of gas collector pressure is an important guarantee for the normal production of coke oven. This paper combines the adaptive fuzzy control algorithm and the fuzzy decoupling rule to control the gas collector pressure, and coordinates the entire system through the establishment of pre-header suction supervisory control. The speci...

PURPOSE: This technical note describes the application of a suite of biomarker assays to samples of brown bullhead liver tissues taken from two locations in Ohio. One was a river reach that had historically been severely impacted by the effluents of a coking plant; the other is regarded as relatively pristine, and is a freshwater estuarine research preserve. The objective of the study was to in...
