[en] Present article is devoted to uranium sorption by activated carbons. Therefore, the technology of obtaining of carbonaceous materials from the wastes of vegetative raw materials was elaborated. For the uranium sorption from sulfuric uranium containing solutions was used activated carbons from apricot shell. The sorption process was studied in dynamic mode.
[en] Present article is devoted to nano particles of metals encapsulated into dendrimer matrix. Therefore, the various approaches to the creation of high active and selective nano structured catalyst systems for the process of selective hydration, hydroformylation, cross-coupling were analyzed.
[en] Present article is devoted to hydrogenation processing of coal tars in order to obtain the raw material for chemical industry. The composition of products of destructive catalytic hydrogenation of coal tars of various coal deposits was studied. It was found that the possibilities of obtaining of hydrocarbon feedstock and oxygen comprising compounds can be extended by application in processing of liquid products of thermal decomposition of coal.
[en] Present article is devoted to means of processing of persistent gold comprising ores in Tajikistan. The methods of processing of gold comprising ores, including hydro sulfation in the nitric acid solution, nitric acid method and some other methods were studied. The flowsheet of processing of gold comprising ores of Taror and Chore deposits was proposed.
[en] Present article is devoted to chlorination of aluminosilicate raw materials with application of coals of Tajikistan. The results of researches on chlorination of aluminosilicate raw materials with application of coals of Zidda Deposit were considered. The conditions of chlorination depending on temperature and process duration, size and quantity of particles were studied. The optimum conditions of chlorination the aluminosilicate raw materials were determined.
[en] Present article is devoted to toxic properties of liquid fraction of thermolysis products of coals of Zidda Deposit. Therefore, the analysis of liquid fraction of thermolysis products of coals of Zidda Deposit which include the determination of harmlessness and acute toxicity was performed. The experiments were carried out on 30 rabbits and 30 white mice.
[en] Present article is devoted to organo mineral wastes of coal development and processing as a complex energy raw material. The technical conditions on using of ash slag products as fuel for application in various types of furnace plants depending on their humidity, ash content and sulphur content was elaborated.
[en] Present article is devoted to study the influence of low frequency pulses of magnetic field on electrophysical properties of coal. The coal of early stage of metamorphism was studied by means of electrochemical impedance method. The dependences on frequency of relative dielectric permittivity, electrical conductivity and dielectric loss tangent for initial, moistened and dried samples were considered.
[en] Present article is devoted to elaboration and creation a pilot plant in order to study the processes of thermal oxidation and carbonization of coal tar pitch and other products of coal carbonization for obtaining an isotropic coke. The installation diagram is described. The technological parameters, including temperature, heating mode, and duration were defined.
