Ways to accelerate the process of chromatographic analysis are examined. The best way to reduce the time of separation is the using of short capillary columns with a small (10 – 50 microns) diameter of the capillary. Restrictions on the use of such columns are discussed, the main one is the necessity to introduce a very small sample volume. This restriction can be overcome by using more than one capillary, the package of a large number of small capillaries, which operates as a single chromatographic column, called polycapillary (PAC). In this case, the sample volume increases, what allows to work in a wide range of concentrations. Different types of PAC are considered. The mechanism of the broadening of the chromatographic peak at the PAC and its properties are discussed. Examples of columns in the mode of gas-liquid and gas-adsorption chromatography are presented. Example of the PAC in catalytic studies is shown.

The possibility of obtaining a new material (a fully deuterated hydrocarbon by Fischer-Tropsch synthesis) is the first step to create the pilot unit. The isotope effect is absent, i.e. the main characteristics of synthesis and the resulting products are determined by the properties of the catalyst and process conditions, regardless of what is used in the original mixture – hydrogen or deuterium. Removing of wax from the catalyst surface occurs in mild conditions and requires no additional equipment or moving of the catalyst in another reactor. The selected catalyst has high stability and can be applied in a pilot unit for a fully deuterated wax. Evaluation of properties of new materials showed the prospects for their application as solvents for NMR, radioactive labels, targets, inhibitors of neutron fluxes, etc.

The reaction of liquid phase oxidation of isopropylbenzene in the presence of nitrogen-containing catalysts at 110–130 °C has been studied. It was found that with the use of N-hydroxyphthalimid and its 3- and 4-methyl-substituted analogs, there is achievement of the conversion of isopropylbenzene 40–50 % with selectivity of hydroperoxide isopropylbenzene formation ≥ 90 % within 2–2,5 hours. Taking into account the amounts of phenol production, the solution of the problem of isopropylbenzene oxidation with usage of N-hydroxyphthalimid by means of increase of the reaction speed and conversion of hydrocarbon together with keeping high selectivity of hydroperoxide, can considerably influence the economic indices of the process.

Strict economic and environmental require to create a new technologies for producing fatty alcohols, which would replace the existing processes, leading to the formation of large quantities of waste, and eliminate or significantly reduce their disadvantages. The most interest in this area are methods based on the using of environmentally friendly oxidant – hydrogen peroxide. The influence of process conditions (initial molar ratio of reactants and temperature) on the ratio of products (alcohols and ketones) liquid-phase oxidation of normal hydrocarbons С10–С13 aqueous solutions of H2O2 on heterogeneous catalyst silikalite titanium (TS-1) is studied. The main reaction products are alcohols and ketones, and the ratio of alcohol in the reaction mass decreases with increasing temperature and decreasing the molar ratio of hydrocarbon/hydrogen peroxide.

The process of gas-phase (200–400 °С) catalytic hydrodechlorination (GDH), the main components of wastes (CH2Cl2, CH3Cl, CCl4) of methyl chloride production from methane was studied. The process is intended for waste recovery in developed technology for «light» olefins production from methane by pyrolysis of methyl chloride. The study was conducted at the laboratory unit on the industrial catalysts for hydrogenation and hydrotreating. Three catalytic systems and conditions for stable flow of GDH are identified. The main products of the process are CH4, CH3Cl, light olefins, and HCl. Concentration of CH3Cl and olefins increases in products using a catalyst Ni–Mo/Al2O3. All products of GDH process can be used in the technological scheme of olefins production, which is to create wasteless and chlorine balanced production of olefins from natural gas (methane). Implementing of olefins production technology is not possible without GDH stage because of significant waste.

A mathematical model of ammonia oxidation over oxide block honeycomb catalyst has been developed. Experimental data of pilot-scale unit operating under process conditions equal to those in UKL-7 type commercial nitric acid plant were used for specification of mathematical model. The results of calculation of NO yield coincide with pilotscale unit’s data. The computer program which permits to calculate conditions of industrial reactors’ functioning was originated.

In this paper, the selection alumina support for crusted palladium catalysts of selective hydrogenation to improve their quality were carried. Effect of calcination temperature on the mechanical, physical and textural properties of the support, as well as the dependence of catalysts quality (life time, activity and selectivity) from the heat treatment conditions of support were studied. Calcination of alumina low temperature forms at 800 °C achieves an optimal balance of strength and textural properties of the support for the synthesis of selective hydrogenation catalysts. Basic requirements for alumina support are: high mechanical strength to crush (more than 40 kg/cm2); strength homogeneity of the material, quantity of granules with the strength less than 4 N/mm2 must be less than 5 % of supports batch; losses due to attrition in the water and in hydrocarbon media is not more than 1,5 % wt. The heat treatment must ensure the stability of texture characteristics of support during the oxidative regeneration (450–500 °C).

Stabilizing influence of boron oxide on crystalline and porous structure of alumina in the time of it exploitation in hydrothermal conditions during 200 hours of skeletal isomerization of n-butylene is examined with use of complex of physic-chemical methods. It is established, that the most stabilizing effect is to be observed by carrying in of boric acid on stage of aluminium hydroxide mould by its more full interaction and more effective attaching of boron oxide in structure of alumina. Deactivating influence of boron oxide on alumina activity in process of skeletal isomerization of n-butylene, caused by formation of significant quantity of strong acid centers, responsible for proceed of cracking and oligomerization processes, is detected. The use of additions, assuring the formation of significant quantity of medium acid centers and minimal quantity of strong acid centers, is recommended with purpose of stabilization of alumina structure.

Dehydroxylation of glycerol in H2 atmosphere on Raney Co catalyst was studied. With temperature increasing from 140 °C to 200 °C at 30 atm H2 conversion of glycerol increased from 14 to 97 %. During 20 hours of experiment the glycerol was completely converted, the yield of 1,2-propanediol was 40 %. The maximum yield of 1,2-propanediol was 44 % and it was obtained at a 200°C temperature and a 30 atm pressure of H2. Dehydroxylation of glycerol in a hydrogen atmosphere on heterogeneous catalysts may be a perspective processing of glycerol produced as a byproduct in the production of biodiesel from vegetable oils and animal fats.
