In present work the paths for obtaining road oil bitumen are presented from wastes of coal Karazhyra field. For improvement quality obtained modification was carried out elementary sulfur. The processes by sulfur allow to obtain viscous high quality.
The article presents the results of a study physicochemical properties, mineral and elemental composition natural mud Moiyldy, Tuzkala, Arasan, Shoshkaly, eastern coast Lake Alakol salt lakes North-Eastern region Kazakhstan.Research on is one current trends carried out by scientists from different countries to identify compounds that cause their positive therapeutic effects.A review available data physical chemical muds in Kazakhstan showed lack systematic studies structure peloids part...
The effect is studied of duration mechanochemical impact, as well modification sequence and grinding on the acidic catalytic properties synthesized catalysts based natural zeolite in conversion n-octane.It shown that highest activity n-octane has a modified nickel-and zinc-based catalyst structured bentonite clay, subjected to treatment for 12 hours after promotion.
In this paper, the subject of study were palladium catalysts modified with humate potassium (HP) extracted from coal at Oy-Karagay deposit in Almaty province Kazakhstan. Catalyst activity was studied p-nitrodiethylaniline (PNDA) reduction reactions an ethanol medium 333K, o-nitrophenol (PONP) a 0.1n KOH 313K, and hydrogenation reaction maleate water 313K.

This paper presents the results of a study on catalytic activity and selectivity nickel palladium catalysts in hydrogenation reactions nitro- acetylene compounds. It was shown that phenylacetylene depend nature modifying additives (Cu, Zn, Ti, Cr, Bi, Ti–Cu, Mn, Fe), based polymer metal complexes depends method their preparation. found for certain concentrations active phase (0.8 wt.%) potassium humate (1.0 wt.%.) catalyst, where were deposited bauxite-094 together, catalyst exhibits...
In this work, the effect of amount catalyst, modifying additives, and phase composition alloys on catalytic isomerizing activity skeletal in hydrogenation reaction hexane-1 is investigated. It has been shown that for all studied catalysts, yield products processes migration isomerization depends very strongly weighed portion catalyst introduced into medium. So, example, hexane-2 with an increase weight increases linearly to 0.5g nickel, while at initial stage reaches 62%. With a further (up...
Results of studies humic substances in the quality natural polymeric modifier for coated palladium catalysts are presented paper, along with synthesis new based on – potassium humate, fixed various inorganic carriers and their catalytic properties studied. The may be placed following order according to activity: Pd-PHum/B-094 > Pd-PHum/Shungit (Sht), proc.1%КОН Pd-PHum/Sht >> Pd-PHum/SiO 2 . More active optimal 0,8% Pd Potassium’s Humat (1%)/B-94 Pd/Shungit 1% КОН.
The porous structure of Semeytau natural zeolite field, catalysts on its basis, and their catalytic activity in the course aromatization n-octane has been investigated. Higher Ni, Zn sample containing catalyst is defined by formation more developed specific surface structure.
Synthesis techniques of the mesostructured alumino-silicates were developed. with various Si/Al ratios was carried out. Textural characteristics and structure's orderliness alumino-silicates' synthesized samples investigated.
Results of studies humic substances in the quality natural polymeric modifier for coated palladium catalysts are presented paper. Synthesis new based on - potassium humate fixed various inorganic carriers and their catalytic properties have been studied. The 0,8% Pd Potassium’s Humat(1%)/B-94 /Shungite 1% КОН optimal.
In this article determination of physico-chemical properties benzene produced from Zhangazhol crude oil by straight distillation. Aim improving quality them hydrotreating in catalysis Со-Gu/Ni-skeleton are investigated.
