Traditionally, the presence of n-paraffins in tar is known to negatively affect fragility, adhesion, and internal cohesion bitumen particles, making paraffinic impractical for producing high-quality bitumen. This study investigates potential enhancement properties through compounding residue from distillation Orkhiv oil with tar. Bitumen samples were prepared via oxidation compounded mixture within a temperature range 210–2700C. The research explores effects duration (ranging 3 12 hours),...
The possibility of using potassium humate as an inhibitor the technological aging oxidized petro-leum bitumen has been investigated. Samples potas-sium obtained from various raw materials, in particular peat and leonardite, were selected compared. Aging coefficients have calculated operational properties modified a binding material for hot mix asphalt It was established that 3.0 wt. % PH-3 added to petroleum bitumen, slows down processes allows obtaining concrete with better characteristics...
The process of tar and industrial petroleum resin “Piroplast-2” joint oxidation has been investigated. experimental results the main regularities researches obtaining resins with carboxyl groups based on pyrocondensate C9 fraction hydrocarbon feedstock pyrolysis have shown. It established that synthesized may be used for modification bitumens.
Aging peculiarities of paving bitumen, which was obtained by different ways, have been studied. Oxidized and residual bitumen produced from oils Ukrainian deposits were used the changes in main characteristics after 5 10 h aging a thin film at temperature 436 K determined processes occurred during Using infrared spectroscopy, structural composition binder analyzed.
Physico-chemical characteristics of threecomponent composition BNB 70/30 bitumen : linseed oil SBS rubber have been investigated.The may be used for the production rolled roofing, installation which does not require heating operation.The dependence softening temperature, ductility, penetration, adhesion, elasticity and water resistance compositions on their structure has examined.
Experimental results concerning main regularities of paraffin tar and petroleum resins joint oxidation are presented. It has been shown that resin in the amount 5 mas % as raw material component allows to intensify improve operational characteristics obtained bitumen.
The main regularities of the modification with a rubber crumb for bitumen produced from residuals crude oils Ukrainian deposits have been studied.The thermal stability has examined using derivatograpgy.The mechanism at low and high temperatures established.The influence technological factors on quality indices modified changes in group composition original were found.
Modification of residual bitumen from Orhovytska oil by Butonal polymeric latexes has been studied.Using such modifiers the softening temperature and elasticity increase penetration decreases.The commercial paving may be produced residuals using latexes.
The physico-chemical properties and group composition of the used mineral motor oils M-10DM NORMAL 15W40, as well fractions obtained a result their thermooxidative regeneration have been studied.The results IR-spectroscopic X-ray fluorescence analysis during are presented.The changes in regenerated described.
The effects of the technological process aging bitumen obtained from residues processing Ukrainian crude oil on bitumen’s operational characteristics, structural-group composition, and thermal stability have been studied. with a thickness 2 mm has conducted under laboratory conditions at temperature 1630C for 5 10 h. Two types bitumen, oxidized BND 60/90 distillation BD 130/200, examined. It found that quality worsens due to aging, e.g. hardness refractoriness increase whereas elasticity...
The oxidation process of the paraffin gas condensate residual has been studied to obtain road bitumen.The investigation results concerning joint with extract oil selective treatment and low-paraffin tars are presented.It determined that bitumen obtained from does not meet requirements setting for bitumen.It is recommended use residuals production building or covering bitumen.
The scheme of the integrated regeneration method for used mineral motor oils (UMMO) has been developed, according to which M-10DM and NORMAL 15W40 were regenerated. A study on changes in physico-chemical properties, qualitative elemental composition was carried out, a mathematical model process built. further applications obtained products proposed. Based results, technological flow chart UMMO material balance calculated.
The process of modifying road bitumen obtained from the residues Ukrainian oils processing with rubber crumb has been studied. dependence softening temperature, ductility, penetration, and elasticity three-component bituminous composition “bitumen : linseed oil crumb” on its formulation examined. Based mentioned a new type cold-applied roofing developed. A flow diagram for production modified special-purpose
The paper deals with the results of study on purification process used mineral and semi-synthetic motor oils in presence crystalline urea. effect main factors (the amount reagent, time, temperature) performance indicators purified was studied. Used for gasoline diesel engines were under established optimal conditions. X-ray-fluorescence IR-spectroscopic studies chemical composition urea are presented.
OIL BITUMEN BND 60/90 PJSC "UKRTATNAFTA" A significant disadvantage of shortening life the roadway is aging binder.The main factors that lead to deterioration properties oxidized oil bitumen are described in article.It found considerable loss binding happens even before commissioning road.An artificial samples according GOST 18180 was performed and indexes after process 5 10 hours were compared.Thanks data, obtained as a result infrared spectroscopy thermographic analysis, changes occurring...
Pyrolysis of petroleum hydrocarbons (including diesel pyrolysis) aimed at obtaining polyethylene also creates certain liquid products which can be used for making so-called resins (PRs). The C9 fraction from pyrolysis contains among others, styrene and its derivatives, indene pentanodiene. Petroleum with epoxy groups (PREs) have been synthesized by oligomerization unsaturated components the in presence 4,4'-azo-bis-[2,3-epoxypropoxy-4-cyano-pentanenitrile] (AEPCP) as an azoinitiator....
Наведено результати досліджень процесів сумісного окиснення гудрону і важкої смоли піролізу, а також модифікування товарного бітуму важкою смолою піролізу. Встановлено принципову можливість використання піролізу в процесах виробництва нафтових бітумів.
У процесі роботи моторних олив у картері двигунів внутрішнього згорання (ДВЗ) відбувається зміна їх експлуатаційних властивостей, тобто оливи "старіють". Таке явище внаслідок фізичних і хімічних процесів товщі робочої ДВЗ. Як наслідок, моторна олива забруднюється залишками незгорілого палива, конденсатом води, пилом, продуктами зношення деталей ДВЗ, термоокисних деструктивних перетворення вуглеводневої частини та розкладу відпрацьованих присадок. Тому, втрачає закладені в неї первинні...
