Effect of Coal Quality on its Desulphurization. 2. Influence of the Inorganic Matter

Abstract

The effect of pyrite size and distribution character, as well as the amount of inorganic matter on the removal degree of sulphur from coal during its oxidative desulphurization and benefication has been studied. The efficiencies of oxidative desulphurization processes for different types of the initial and concentrated black coal have been compared.

Improved Method for Determining Microbiological Contamination of Fatty Acid Methyl Esters and Blended Diesel Fuels

“…Further works of A.M. Nastyukov, as well as the research of A. Bayer laid the foundation for numerous studies in the field of arene-formaldehyde polycondensations, which gave an impetus to the production of various types of resins, which are still widely used. [6][7][8][9][10] At the Department of Chemical Technology of Oil and Gas Processing of the Lviv Polytechnic National University, research is being conducted related to the production of arene [11][12][13][14][15][16][17][18][19][20][21][22][23] and phenolformaldehyde [24][25][26][27][28][29][30][31] resins with the aim of obtaining bituminous materials with improved operational properties.…”
