Dear readers,

welcome to the website of the journal 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 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.

Supercritical water gasification of isopropyl alcohol on vertical continuous apparatus: process cond

Eliška Purkarová, Karel Ciahotný, Marek Šváb, Siarhei Skoblia, Lucie Zoderová, Zdeněk Beňo

Increasing world energy consumption leads to the search for new technologies that are able to obtain power. Also due to the increasing amount of waste stream would be suitable to find mechanisms to gain energy from them. Supercritical water gasification is a conversion process that represents a potential for the technology on degradation of liquid organic wastes to produce usable energy gases (methane, hydrogen, CO, higher hydrocarbons) along with the treatment of waste water. Supercritical water gasification is a very complex process, hence is necessary a detailed examination on experimental equipment using model compounds. In this paper the results of isopropyl alcohol gasification on a vertical continuous apparatus are depicted. Experiments were carried out under various process conditions to determine the most appropriate setting for an effective gasification.

Testing of Chosen Czech Limestones for Chemisorption of CO2

Lenka Jílková, Veronika Vrbová

We tested ten natural limestone materials based on calcium carbonate using special sorption system for exploration of usability these limestones in high temperature carbonate looping technology. This technology can be used in industrial for carbon dioxide and other acidic substances removal from flue gases. The chemisorption tests with limestones were performed in small laboratory scale in fixed bed in CO2 atmosphere at 650 °C. We wanted to assess the verification of using these materials for the high temperature sorption of carbon dioxide and pick up the best one for possible testing in larger scale. The process of CO2 sorption should be used for removal of carbon dioxide and other acidic substances from flue gases. The sample with lowest CO2 sorption capacity was the Úpohlavy sample. Libotín sample, Čertovy schody sample and Tetín sample were the samples with best sorption capacities of carbon dioxide.

Hydrogen production via water gas shift reaction on a nickel based catalyst

Erlisa Baraj, Karel Ciahotný, Tomáš Hlinčik, Veronika Šnajdrová

In this paper the fundaments of the water gas shift reaction (WGSR) were described. An overview of the most commonly used catalysts for industrial applications as well as catalysts that are being developed are discussed. The main focus of this work was to perform catalytic activity tests for the WGSR in a laboratory apparatus. The tested catalyst was a nickel-based catalyst. Tests were performed using feed gas consisting of 50 mole % carbon dioxide and the balance nitrogen. Catalytic tests proved that the selected nickel-based catalyst was active for the WGSR. However, it was observed that methanation side reaction also took place.
