The Influence of Organic and Inorganic Additives on the Specific Electrical Resistance of Coke

This study aimed to evaluate the effect of both inorganic (boron carbide nanopowders and silicon carbide (carborundum) and organic lean (petroleum coke) additives on the quality of coke produced in a laboratory furnace, as well as on its electrical properties. Analyzing the results of the quality assessment of the obtained coke, it can be argued that the addition of a fixed amount $(0.25-0.5 \ wt.\%)$ of non-caking nanoadditives allows to regulate the process in the plastic state in order to increase the coke strength.


Polylactide composite materials with organic filler-modifier starch, inorganic filler -calcium carbonate and plasticizer - epoxidized soybean oil for 3D printing have been developed. On the basis of the modular deformation method of calculation the elastic-plastic and deformation properties of the developed modified polylactide materials are determined. The change of modulus of deformation, modulus of elasticity, modulus of high elasticity depending on the composition of the composite is revealed.

Influence of Potassium Humate on the Technological Aging Processes of Oxidized Petroleum Bitumen

The possibility of using potassium humate as an inhibitor of the technological aging of oxidized petro-leum bitumen has been investigated. Samples of potas-sium humate obtained from various raw materials, in particular peat and leonardite, were selected and compared. Aging coefficients have been calculated and operational properties of modified bitumen as a binding material for hot mix asphalt have been investigated. It was established that 3.0 wt.

Influence of Natural Clinoptilolite Modification with Ions and Zero-Valent Silver on Its Sorption Capacity

Areas of use of natural clinoptilolite were analyzed. The emphasis was placed on its application in water technology and medical practice. The results of the study of the dehydration of clinoptilolite at different temperatures were presented. The influence of the activation temperature of clinoptilolite on its sorption capacity for silver ions was determined. The effect of modification with ions and highly dispersed silver particles on the sorption capacity of various zeolite fractions with respect to water was investigated.

Effect of Modifying the Clinoptilolite-Containing Rocks of Transcarpathia on Their Porous Characteristics and Catalytic Properties in the Conversion of C6-Hydrocarbons

The efficiency of modifying the Ukrainian clinoptilolite-containing rocks to improve their adsorption and catalytic properties was evaluated based on the data of XRD, IR spectroscopy, low-temperature N2 adsorption, and testing in the micropulse catalytic transformation of C6-hydrocarbons. The effect of such modification on the distribution of reaction products was established.

Poly(Vinyl Chloride)-Polystyrene Materials with Polymer-Silicate Fillers

The features of obtaining and modifying Ba- and Zn-containing polymer-silicate fillers have been researched. The influence of polystyrene modifiers (suspension and impact-resistant polystyrene) and finely dispersed Ba- and Zn-containing polymer-silicate fillers on the gelation process, view of flow curves, rheological properties: flow index, flow limit, thermal stability, surface hardness and elasticity of plasticized poly(vinyl chloride) have been discovered.

Influence of Initiators on the Adhesion Properties of Bitumen Modified by Natural Origin Epoxide

The article is presenting a modification of bituminous binder with ecological epoxidized rapeseed oil (BERO) in the presence of the initiator (hardener). Adipic acid (AA), maleic anhydride (MA) and polyethylene polyamine (PEPA) were used as the initiators. The effect of modification temperature and, as well as initiator nature, on the bitumen properties was determined. Bitumen modified with BERO was evaluated by the following indicators: softening temperature, penetration, ductility, and adhesion to the glass.


The technology for producing montmorillonite modified with polyionenes has been developed. It was shown that macromolecular polymer intercalation of the quaternary ammonium salt of montmorillonite intercrystalline space is accompanied by an increase in interlayer distances from 1.08 to 1.67 nm. A method for the synthesis of montmorillonite modified with polyionenes is proposed.

Research of the influence of modified polyethyleneaminoguanidine derivatives on composites properties on polypropylene based

 The properties of the filled polymer compositions largely depend on the nature and surface properties of the fillers- basalt fiber. The possibility of modifying the surface of the basalt fiber with commercial polyhexamethyleneguanidinehydrochloride and non-commercial polydiethyleneaminoguanidine - appretes, were demonstrated for the first time.

Іnfluence of acoustic radiation of ultrasonic range on modification of natural clinoptilolite by ions of argentums

It was found that under the action of acoustic vibrations of the ultrasonic (US) range, the rate of sorption of Argentum ions and the static capacity of clinoptilolite are much higher than for the original natural zeolite. Pre-activation of the zeolite at 350 °С allows to increase the content of Argentum ions.An increase in both the power of the US-radiation and the modification temperature makes it possible to increase the static capacity of the zeolite.It is shown that the process of modification of clinoptilolite occurs mainly in the transition region.
