Environmental aspects of underground coal gasification

Jerzy ŚWIĄDROWSKI*, Krzysztof STAŃCZYK – Central Mining Institute (GIG), Katowice, Poland Please cite as: CHEMIK 2016, 70, 5, 239–246 The concept of underground coal gasification involves direct obtaining of energy stored in coal beds that are difficult to mine using known and conventional methods, in a manner justified by economic, environmental and social benefits. Economic effect is shown by an improvement of coal use energy efficiency and its competitiveness by e.g. production of liquid and gaseous fuels...

The selection of oxide support of the catalyst for N2O emission abatement

Marek INGER*, Katarzyna ANTONIAK-JURAK, Monika RUSZAK, Paweł KOWALIK, Marcin WILK – New Chemical Syntheses Institute, Puławy, Poland Please cite as: CHEMIK 2016, 70, 5, 255–260 Nitric acid plants are one of the largest industrial sources of nitrous oxide (N2O) emission, which is an undesirable by-product, formed during catalytic oxidation of ammonia. Its concentration in exhaust gases (socalled tail gases) depends on the operating parameters of the installation and can achieve the level of 2000 ppm [1]. Industrial...

Reliable renewable energy – application of electrochemical capacitors for electrical energy storage

Anna DETTLAFF*, Monika WILAMOWSKA-ZAWŁOCKA, Ewa KLUGMANN-RADZIEMSKA - Faculty of Chemistry, Gdansk University of Technology, Gdansk, Poland Please cite as: CHEMIK 2016, 70, 5, 247–254 According to the United Nations projections of population growth, the world population of humans will reach 13 billion at the end of the XXIst century. The population growth consequently leads to increased demand for electrical energy, which results in greater interest in renewable energy sources. Unfortunately, in this case, conversion of the energy...

Glycerol steam reforming over Ni-Re/α-Al2O3 catalysts

Marcin CICHY*, Tadeusz BOROWIECKI – Department of Chemical Technology, Faculty of Chemistry, Maria Curie-Sklodowska University, Lublin, Poland Please cite as: CHEMIK 2016, 70, 5, 261–269 High growth of fossil fuels prices and tighten environmental requirements, which restricts emissions of the contaminants released to the atmosphere affected on increase of the share of energy possessed from renewable sources, including biomass. One of the most popular ways of processing vegetable oils is their transesterification, which leads to obtaining so...
