Abstract The article deals with the preparation and characterization of titanium dioxide thin films containing pyrolytic carbon as potential UV protection for photovoltaic devices. used an additive was obtained by pyrolysis methane, main product which is turquoise hydrogen, a by-product process. resulting material characterized Raman spectroscopy, scanning electron microscopy energy dispersive spectroscopy. Titanium dioxide/pyrolytic composite were prepared sol-gel method, followed...
Abstract The processes of degradation engine oils operated in passenger cars a uniform fleet 25 vehicles were analyzed for oxidation content using infrared (IR) spectroscopy. As part the experiment, changes occurring during actual operation (under conditions which can be described as “harsh”, i.e., short distance driving, frequent starting engine, and extended idling) have been observed. An evaluation Fourier transform spectroscopy (FTIR) spectrum an oil sample was presented. spectra both...
Three vegetable oils (rapeseed oil, palm and soybean oil) were isomerized (the so-called zeoforming process) using two different ZSM-5 catalysts (A or B) at a constant temperature (300 °C) liquid hourly space velocity (LHSV) (1.0 h–1) variable pressure (1.7, 2.5, 4.0 MPa). The obtained zeoformates hydrotreated under conditions (temperature, 340 °C; LHSV, 0.5 h–1; pressure, 4.5 MPa; hydrogen/feed ratio, 1500 Nm3/m3). hydroraffinates exhibited diverse contents of n-paraffins (24–83 wt %),...
Nowadays, the main reason for blending of biofuels stems from necessity to reduce greenhouse gas emissions. Depending on market requirements, all gasoline fuels should be blended with 5–25 vol % ethanol. Low-blend ethanol gasolines are characterized by alcohol contents ranging 5 10 in Europe and up 15 United States. The achievement new emission reduction targets implementation requirement replace fossil energy renewable set out RED Directive 2009/28/EC will demand 20–25 Europe. Such blends...
Polyolefin fibres used in cementitious composites – manufacturing, properties and application
This work describes research conducted on the zeoforming process of rapeseed oil and using zeoformat as a feedstock for hydroconversion leading to hydrocarbon fuel biocomponents. The raw products, including hydroraffinate zeoformat, were examined 1H NMR techniques confirm occurrence oligomerization fatty acids. Based tests performed, it was determined that, during vegetable oil, partial decomposition processes occurred in triglycerides. Monoglycerides, diglycerides, carboxylic acids formed,...
Rapeseed vegetable oil was initially zeoformed in the temperature range of 200–300 °C and at a pressure 1.7 MPa using catalyst containing ZSM-5, obtained zeoformates were subsequently converted into hydrocarbons [hydrorefined (HVO)] through process hydroconversion. The resulting hydroraffinates (HVO fuel biocomponents) contained n-paraffins, isoparaffins, up to 15% aromatic compounds. It has been established that compounds have good low-temperature properties [cold filter plugging point...
Glycerine (glycerol) is a polyol consisting of three carbon atoms bonded to hydroxyl groups. It by-product the transesterification triglycerides, such as animal fats, vegetable oils, or used cooking oils during biodiesel production process. Crude glycerine subject purification processes resulting in distilled containing at least 99.5% glycerol. Currently, produced high-quality food, pharmaceutical, and cosmetic industries. Recently, technologies for converting glycerol other chemicals...
Iron-based FBC additives with a different length of the organic stabilizing ligands: undecylenic acid (C11) and oleic (C18) were synthesized. A physicochemical characterization materials structure morphology was performed by means Raman spectroscopy, electron diffraction TEM imaging. It found that reactivity iron-based fuel borne catalysts depends on disperser size formed hematite nanoparticles. Reactivity tests in soot oxidation reaction both at laboratory scale commercial light oil burner...
Ethanol or ethanol-containing fuels can contain trace amounts of contaminants in the form sulfates. Sulfates are very poorly soluble ethanol, and despite this, according to some sources, they be favorable for deposit formation on inlet valves combustion chambers injector tips. However, this issue has raised a lot doubts now, results studies carried out not explicit terms sulfates contained SI engines contribution deposits question. Under project engine, tests were performed five ethanol...
The goal of the article was to carry out a comparative research on propensity standard-class commercial diesel fuel, consistent with requirements EN-590 standard, zinc catalysts various chemical structures introduced, form deposits tips fuel injectors compression ignition engine. Studies carboxylic salts type dissolved in and dispersed oxides/hydroxides were planned. influence dialkyldithiophosphates (ZDDP) deposit formation not investigated because their complex structure inability evaluate...

The article concerns the proposal of a new method managing carbon being by-product methane pyrolysis process. Methane is one methods for producing turquoise hydrogen. Its greatest advantage lack CO2 sequestration, which greatly simplifies process and makes this economically ecologically competitive compared to other obtaining Carbon material in form flake was characterized using Raman spectroscopy, SEM EDS. obtained pyrolytic then used as an admixture titanium dioxide. Thin films dioxide...
Abstract Petroleum plasticisers are applied as softening additives in rubber vulcanisation processes and components of mixtures the production process. They contain polycyclic aromatic compounds exhibiting carcinogenic mutagenic effects. Since 2010, European Union has banned use high-aromatic DAE plasticisers. The petroleum industry tyre manufacturers developing new types best alternative to is TDAE plasticisers, obtained mainly by selective solvent refining. dewaxing process classic was...
