Welcome to the website of the journal Paliva ("Fuels"). The journal is Open Access, with articles published under CC BY 4.0 license. The journal is issued online only.

Paliva 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.


Paliva (Fuels) included in Scopus database

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.

Ru/Al2O3 catalyst-assisted processing of waste silane-grafted cross-linked polyethylene

Pavel Straka, Olga Bičáková, Jaroslav Cihlář

Waste crosslinked polyethylene (XLPE) can be a source of valuable hydrocarbons for further use. XLPE is widely used material which – unlike polyethylene – is very stable both chemically and mechanically. Therefore, its waste is difficult to process. A very promising way is slow pyrolysis catalyzed by ruthenium (Ru/Al2O3) which allows the conversion of waste into hydrocarbons via degradation of rigid chemical structure of cross-linked material. High hydrocarbon yields (91–92 wt.%) were achieved by slow pyrolysis without or with catalyst, but significant changes in the composition of resulting gas and oil were found with the Ru/Al₂O₃ catalyst. To reveal the possibilities of using this catalyst for processing of XLPE at a relatively lower final temperature (max. 480 °C, mostly 450–470 °C), an effect of the catalyst on degradation of XLPE structure and related rheological properties of XLPE melt was investigated. It was found that the activation energy of degradation decreases significantly in the presence of the catalyst and the degradation is greatly facilitated by Ru/Al2O3 at the defect sites of the XLPE structure (the tertiary carbons). By the catalyst, the torque for XLPE melt and the its shear viscosity are significantly reduced already at 250 °C. Thus, Ru/Al2O3 catalyst, even in very small amounts (1 wt.% Ru), significantly promotes the degradation of XLPE structure and reduces the solid pyrolysis residue. This finding greatly facilitates the processing of waste XLPE. The catalytic mechanism of action of Ru is outlined and the equations for the XLPE cleavage are given. The main product of processing, pyrolysis oil, can be used as a clean heating fuel, or oil for further use, or a source of solvents, liquid and solid hydrocarbons, especially paraffin.
