A gas coal (B) was used to study the effect of volatiles on sulfur removal from a high organic-sulfur coking (A) perspective mass transfer conditions. The driving force and resistance were analyzed in terms fluidity development, permeability plastic stage flow, volatile matter release. Carbonization using vertical horizontal stacking modes two coals designed according release directions during ...

To facilitate predictions of the transport and fate of contaminants at future coal conversion facilities, rates of microbial transformation of polycyclic aromatic hydrocarbons were measured in stream water and sediment samples collected in the vicinity of a coal-coking treated wastewater discharge from November 1977 through August 1979. Six radiolabeled polycyclic aromatic hydrocarbons were inc...

Understanding of the influencing factors of industrial sector carbon dioxide emissions is essential to reduce natural and anthropogenic greenhouse gas emissions. In this paper, we applied the Logarithmic Mean Divisia Index (LMDI) decomposition method based on the extended Kaya identity to analyze the changes in industrial carbon dioxide emissions resulting from 39 industrial sectors in Inner Mo...

This paper uses nonparametric causality-in-quantiles tests to examine the asymmetric effects of climate risk perception (CRP) on thermal and coking coal futures high-frequency returns volatilities. The results show that CRP significantly impacts dynamic market, with volatility indicators exhibiting asymmetry at different percentiles being more pronounced in a downward market. influence mainly t...

In this study, the in situ compressive strength of iron coke high-temperature carbonization was investigated. The strengths briquettes with 20, 30, and 40% ore at 700, 800, 900, 1000°C for 3 h were systematically studied. mass loss microstructure during also results showed that increased content from 20 to 40%. liquid phase slag calculated using FactSage software. Results an increasing temperat...

Over the three-day gasification test of a large coal block with oxygen in atmospheric pressure conditions, yield and composition tar collected was investigated. The sampled approximately every 7 h into sorption tubes directly from reactor outlet. Sand, moisture content 11%, used as an insulating material to simulate environment gasified seam. Light aromatic hydrocarbons (BTEX), phenols, polycyc...

The valorisation of oil distillation residues constitutes a major problem for refineries. Thermal processes like visbreaking and delayed coking are still quite diffused technologies. This paper presents some major aspects of the delayed coking kinetic modelling and some preliminary results compared with experimental data. A mechanistic approach has been adopted; it allows describing the process...

A geological-statistic analysis of commercial resources and the predictive coal-bearing potential fields South-Western coal region, principal promising part Lviv-Volyn Coal Basin, has been carried out. Based on detailed systematization data from prospecting exploratory-assessment works regarding depth occurrence thickness seams, ash content, sulphur content grade composition coal, Tyagliv Lyube...
