Characterization of liquid products from waste tires pyrolysis

Bogumiła WRZESIŃSKA*, Roman KRZYWDA, Tomasz WĄSOWSKI, Leon GRADOŃ – Faculty of Chemical and Process Engineering, Warsaw University of Technology, Warsaw, Poland Please cite as: CHEMIK 2016, 70, 10, 611–615 It is estimated that about 1.5 billion tires are produced worldwide each year. After use they pass to the stream of waste, representing a significant part of them [1]. So far, the main method of tires thermal recycling was burning, mainly as a fuel in cement plants. An...

CO2-to-methanol conversion – an alternative energy storage solution

Andrzej WILK*, Lucyna WIĘCŁAW-SOLNY, Tomasz SPIETZ, Adam TATARCZUK – Institute for Chemical Processing of Coal, Zabrze, Poland Please cite as: CHEMIK 2016, 70, 10, 626–633 Using carbon oxides in synthesis of fuels is an extensively researched subject, since studies devoted to this problem have been conducted as long as since the beginning of the previous century. The two major reactions were the Sabatier process, which consisted in carbon dioxide hydrogenation to methane, and the Fisher-Tropsch process, being...

The use of zirconium oxy-hydroxide for removing anions from liquid industrial waste

Barbara SOŁTYSIK*, Jolanta MIŚKIEWICZ, Mariola BODZEK-KOCHEL, Joanna GLUZIŃSKA, Marzena PYSZ – New Chemical Syntheses Institute, Inorganic Chemistry Division „IChN” in Gliwice, Poland Please cite as: CHEMIK 2016, 70, 10, 644–649 Environmental requirements necessitate the implementation of the so-called clean technology, whose main determinants are: sustainable use of raw materials, improvement of energy efficiency and action in the broad sense of environmental protection. Important role in this type of technologies play a zirconium compounds, such as zirconium dioxide...

Overview of photobioreactors for the production of biodiesel

Agnieszka PATYNA*, Stanisław WITCZAK – Department of Process Engineering, Opole University of Technology, Opole, Poland Please cite as: CHEMIK 2016, 70, 10, 634–643 Microalgae are the longest living autotrophic taxon in the world [1]. Algae are tissueless organisms, protozoans or simple multicellular organisms. Among them are both prokaryotic microalgae (cyanobacteria, otherwise known as blue-green algae), as well as, eukaryotes, eg. green algae (Chloroxybacteria), red algae (Rhodophyta) and diatoms (Bacillariophta). Algae can reproduce sexually or asexually [2÷4]. They...

Directions and possibilities of the safe nanowaste management

Bożena MROWIEC* – Institute of Environmental Protection and Engineering, University of Bielsko-Biala, Bielsko-Biala, Poland Please cite as: CHEMIK 2016, 70, 10, 593–596 Nanotechnology is a field of growing scientific interest due to the properties of engineered nanomaterials (ENMs) which are utilized in a broad spectrum of applications. The International organization for Standardization (ISO) classified nanomaterials into three main groups: nanoparticles (all three dimensions between 1 and 100 nm); nanoplates (one dimension between 1 and 100 nm); and...

Investigation of spraying lances used in low power boilers for non-catalytic reduction of nitrogen oxides (SNCR)

Roman KRZYWDA*, Bogumiła WRZESIŃSKA, Tomasz WĄSOWSKI – Faculty of Chemical and Process Engineering, Warsaw University of Technology, Warsaw, Poland Please cite as: CHEMIK 2016, 70, 10, 605–610 Starting from 1990 norms concerning emission from power plants become more and more restrictive. In case of coal burning the limitation concerns among others nitrogen oxides (both NO and NO2 in equivalent of NO2). Present standards are defined by Regulation of the Minister of the Environment from 2014 [1]. For the...

Vermicomposting of sewage sludge

Marta BOŻYM* – Faculty of Mechanical Engineering, Opole University of Technology, Opole, Poland Please cite as: CHEMIK 2016, 70, 10, 616–619 The term “vermicomposting” or “vermiculture” refers to the use of earthworms for composting organic matter from sewage sludge and the latest biotechnology which helps in giving biofertilizers in the term of “vermicompost”. In the first half of the twentieth century the vermicomposting process of agricultural waste were started the Americans. In Poland, vermicompost manure produced since...
