Dear readers,
welcome to the website of the journal Paliva (Fuels). The journal is published quarterly in online format, which allows a broad and rapid access for readers. The journal is open not only to researchers but also for technicians and other professionals working in plants, refineries, power stations, gasworks and companies processing, handling or trading both fossil and alternative fuels. The aim of the journal is to share information between professional research organizations and users of research results.
Since 2010 the journal Paliva (Fuels) is included in the list of recognized peer-reviewed journals, issued by the Research, Development and Innovation Council of the government of the Czech Republic. Amongst other requirements that must be met to be a member of the group of journals, all papers published in the journal undergo a review process by two independent reviewers.
We sincerely hope you become regular readers of the journal and perhaps contributors in its future issues. Thank you.
Karel Ciahotný
editor in chief
In 2019, when Paliva celebrated its 10th anniversary, the journal was succesfully evaluated and included in Scopus. Paliva is the only periodical in its research field published in the Czech Republic indexed by Scopus database. Since then, we expect further increase of the quality of published papers and greater proportion of papers written in English. It is also an oncoming opportunity for new authors from both industry and academic sphere.

We are proud to annouce that Paliva (Fuels) Journal was successfully evaluated by Chemical Abstracts Service (CAS) and included to the CAS databases among more than 10 thousand scientific journals worldwide. Starting with the 2015 issues, CAS collects bibliographic information and abstracts of articles issued by Fuels, which makes the access to the findings published in the journal substantially easier for scientists and field specialists from over the world.
Rising demand for plastic materials results in increasing volumes of plastic waste generated globally. This poses a question of waste collection and handling of the growing waste volumes. With quality limitations of reuse and mechanical recycling, especially end-of-life mixed plastic waste is mostly landfilled, incinerated or lost to environment. Thermochemical recycling, especially pyrolysis, has been historically explored as an attractive alternative waste processing method with a potential to valorise the plastic waste into energy, fuels and more recently also chemicals and virgin polymers. Thermochemical plastic waste processing and treatment of the intermediates towards the final products have been found to be studied mostly in isolation. Therefore, this study provides a combined view. Updated state of pilot and demonstration projects is reviewed. Typical characteristics of plastic waste pyrolysis products are introduced and the areas of potential impacts on existing plants are highlighted. In order to address the circularity and economic aspect, a summary of recent relevant LCA and business studies is provided, showing common sensitivity factors and main assumptions used therein. Overall, this review summarizes the background behind the recycling of waste plastics and presents it in context of challenges and opportunities of integration with existing refining and petrochemical infrastructure.
This research attempted to reduce sulfur and ash content for enhanced coal recovery by the froth flotation technique. Dukki district (Pakistan) coal was upgraded using a flotation technique followed by acid leaching. Tests on flotation concentrate were carried out to improve the grade of coal further. Tests were carried out to investigate and determine the effect of critical parameters like particle size, pH, and pulp density on reducing ash and sulfur content from coal. The particle size was observed to have the most significant role in coal ash and sulfur reduction, followed by the pH, and pulp density, respectively. The optimum particle size, pH, and pulp density values were 74 μm, 9 and 10%, respectively. The results from the flotation study on a laboratory scale at optimized conditions were a 54.1% increase in total carbon, a 42.12% reduction in ash, and a 38.32% reduction in sulfur. Final ash and sulphur contents in clean coal were 15.2% and 1.65%, respectively. Thus, clean coal can preferably be used in power plants and the cement industry in the country.
The corrosion protection capability of reagent C-1 with bactericidal-inhibitory properties was studied in laboratory conditions in neutral, acidic and alkaline mediums and the concentration of the reagent was in the range of 10-25 mg/l. Desulfomicrobium and desulfovibrio desulfuricans strains of sulphate-reducing bacteria extracted from formation water of oil well no. 1802 of Bibiheybatneft OGPD, SOCAR field were used as the research object. For comparison, reagent free and reagent-based mediums were used in the research process. In laboratory conditions, the effect of reagent C-1 on the incubation period of sulfate-reducing bacteria was investigated for fifteen days in postgate-“B” nutrient medium. It was determined that having a bactericidal property, reagent C-1 affects the life activity of bacteria significantly. It was revealed that the highest bactericidal effect occurs at a concentration of 25 mg/l of reagent C-1 and the effect of corrosion protection from bacteria is 85%.
2-Ethylhexyl nitrate, also referred to as cetane booster or cetane improver, is now commonly used as a diesel fuel additive to increase cetane number. It is already used in the refinery blending of a final product. It can also be obtained in the form of a supplementary additive for a final consumer. Its positive effect on the cetane number is undisputed and proven, but at the same time, due to the nature of its effect on the combustion process, the measured oxidation stability of diesel fuel may be adversely affected. This negative effect has been observed in the measurement of oxidation stability according to EN 16091 and also in a test simulating long-term storage of diesel fuel, the results of which are presented in this publication. The effect of 2-EHN on the carbonisation residue according to EN ISO 10370 was also studied in the context of monitoring the oxidation stability of diesel fuel with the addition of 2-EHN. In this case, the negative effect of 2-EHN was not demonstrated.
