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.
