Opis:: The proposed article involves an investigation of the processes taking place during the preparation of mixed fuels that are combined directly before combustion. The fuel dose formed in this way must take into account the qualitative and quantitative composition of the fuels and the amount of air in the process. Given that liquid fuels similar to gasoline (e.g. methanol, ethanol, butanol) are characterized by different properties, their comparison would be useful in order to use their ratio to influence the combustion process. The process of fuel preparation plays a decisive role in this issue. The article describes abilities of modelling the injection of various fuels simultaneously to the combustion chamber for creating fuel mixture directly before ignition. First part of the article consists of analysis of light hydrocarbon fuels mixing abilities, supported with present research data. Next part describes the evaluation of execution of the assumed system – two fuel injectors with analysis of spray penetration. The modelling of the injection and spray was performed in the AVL FIRE 2014.2 environment and the results were presented. The injection possibility was proven by injecting the fuel to the combustion chamber model. Local values of air-fuel ratio, density and ambient pressure were presented to better understand the potential in mixing fuels directly before ignition. The conclusion includes description of fuel mixing abilities, influence of various fuels on creation of a stratified mixture and definition of controllability of charge ignition.

Opis:: Term “jet fuel” is well known and recognized worldwide - it applies to aviation product used to power all turbine engines in aircrafts and helicopters. Its’ properties are clearly and strictly defined in international specifications. However, in the discussion concerning jet fuels, and in most research material, many people seem to forget that this fuel is a mixture of different hydrocarbons, is produced from different feedstock (crude oil from different sources available worldwide) and as a final product is obtained with different production processes. Thus, however jet fuel must meet the requirements defined in international standards, these fuels differ each other and as a result, differences can be observed in logistic chain and in combustion process. This paper points out some differences between jet fuels and its aim is to convict users, researchers and all people in aviation industry dealing with jet engines operation, that - when talking about jet fuel - many factors and details about final product must be considered, and this type of product should not be seen as single-type fuel, as most people see it now. The article has been prepared within the research project funded by the National Science Centre in Poland and granted with decision no. DEC-2011/01/D/ST8/06567.

Opis:: On the off chance that methods which reduce the global CO2 content are unavailable and inefficient, the increasing CO2 levels will lead to a synchronized rise in temperature across the world. The conversion of this abundant CO2 into hydrocarbons like CH4, CH3OH, CO, HCOOH and hydrogen fuel using different techniques and their use for power could assist with the world’s energy deficiency and solve the CO2 reduction-energy nexus. In this study, photocatalytic CO2 conversion by sunlight will be of primary focus since this bears a resemblance with the regular photosynthesis phenomenon. This work also portrays the writings that have narrated the development of mixtures of two or more carbon ions (C2 ̧) within the photocatalytic reduction of CO2. This paper thus comprises the energy required for CO2 photoreduction, the kinetics mechanisms and thermodynamics requirements. The reaction of CO with water and the hydrogenation of CO2 are covered to understand the gap of Gibb’s free energy between both of the reactions. Likewise, the summary of different metal-based co-catalysts, metal-free co-catalysts and their selectivity towards CO2 reduction by photocatalysis and reduction of CO2 into various hydrocarbons, fuel and materials have also been examined.

Opis:: W artykule omówiono typy podziemnych magazynów węglowodorów płynnych: gazu oraz ropy i paliw płynnych, eksploatowanych na terenie Polski, wraz z podstawowymi danymi technicznymi. Przedstawiono w skrócie historię rozwoju podziemnego magazynowania gazu oraz ropy naftowej i paliw – benzyn oraz oleju napędowego i opałowego. Omówiono rolę organów nadzoru górniczego, jaką jest kontrola i nadzór nad przestrzeganiem przepisów w zakresie bezpieczeństwa i higieny pracy, bezpieczeństwa pożarowego, ratownictwa górniczego, gospodarki złożem w procesie jego eksploatacji, rekultywacji gruntów i zagospodarowania terenu. Wskazano na najbardziej istotne dla bezpieczeństwa, w tym bezpieczeństwa powszechnego, zagadnienia i zagrożenia występujące przy eksploatacji podziemnych magazynów węglowodorów oraz omówiono zagadnienia prawidłowej ich eksploatacji, uwzględniając awarie zaistniałe w czasie budowy i eksploatacji magazynów węglowodorów, zatrudniania podmiotów wykonujących powierzone im czynności w ruchu zakładu górniczego, a także kwalifikacji osób dozoru ruchu.
The paper discusses the types of underground storage of liquid hydrocarbons – gas, crude oil and liquid fuels – exploited in Poland, along with basic technical data. A brief outline of the development of underground storage of gas, crude oil and fuels – gasoline, diesel and heating oil. It discusses the role of mining supervision authorities, which is control and supervision over compliance with provisions in the field of occupational health and safety, fire safety, mine rescue, deposit management in the process of its exploitation, land reclamation and land development. The most important issues related to safety, including general safety, issues and threats occurring in the exploitation of underground hydrocarbon storage were discussed, and the issues of proper exploitation were discussed, taking into account failures occurring during the construction and operation of hydrocarbon storage facilities, employment of entities carrying out activities entrusted to them in mining plant operations, as well as the qualifications of operation control persons.
