The recycling potential is being actualized due to the trends in production and use of powder liquid combustible materials from waste a mining enterprise cycle mining, enrichment processing (polymer packaging containers explosives, large tires rubber products during operation vehicles, coal coke breeze coking coal, oil vehicles mechanization equipment). In material under consideration, SWOT ana...

In the presence of various catalysts (TiCl4, AlCl3, H2SO4), process obtaining a coumarone-indene-carbazole resin (CICR), which is produced from liquid products coal coking, and its subsequent use for bitumen modification was investigated. The influence catalyst type on yield modifying properties CICR (change in thermoplastic adhesive after adding obtained resins to them) studied. effect amount ...

OBJECTIVE To determine whether there was excess ill health in people living near a coking works, and if so whether it was related to exposure to coking works' emissions. DESIGN Populations varying in proximity to the coking works were compared with control populations. Health data were correlated with available environmental data. METHODS Analysis of routinely collected mortality, cancer re...

Biodesulfurization of coal has been carried out in batch culture of single strain and mixed culture of sulfur oxidizing bacteria. The pure cultures of Thiobacillus thiooxidans and Thiobacillus ferrooxidans utilized inorganic sulfur content of Malaysian coal. The chemolithotroph bacteria were able to grow on coal and metabolize the coal's sulfur content. The batch cultures of coal with 3-5 perce...

A comprehensive study on the acidic and coking properties of selectivated H-ZSM-5 catalysts during xylene isomerization has been made. The effects of surface modification by pre-coking and silylation on the nature and location of carbonaceous deposits and on related acidic features of the spent catalysts were respectively characterized by Xe NMR of adsorbed Xe and solid-state P MAS NMR of adsor...

The adsorption pore structure is the key affecting technology of enhanced coal bed methane recovery (ECBM). In this paper, nitrogen measurement (NAM) and low-field nuclear magnetic resonance (NMR) methods are used to test structural parameters pores four samples with different metamorphic degrees. Combining fractal theory, applicability physical significance dimensions obtained from models anal...

The successful supply of an economy with coal fuel, for a country that carries out its large-scale extraction and import, is complex production logistics problem. Violations the usual scheme in conditions crises energy markets, international conflicts, etc., lead to problem simultaneous restructuring entire scheme. This requires changes directions capacities domestic imports. In this article, a...
