The literature on the existing processes for the synthesis of γ-acetopropyl alcohol (acetopropanol, 5-hydroxypentan-2-one, APA) is reviewed. This substance is used to produce vitamin B1, antimalarial drugs and polymers. The promising methods for APA production are the hydrogenation-hydration of sylvan (2-methylfuran), hydrogenation of furfural, and syntheses based on allyl acetate, sodium acetoacetic ether, and γ-butyrolactone.

The reactivity of different forms of adsorbed acetic acid on the Pt-ReOx/TiO2 catalyst was studied. To this end, in situ FTIR spectroscopy at T = 200 °С was used to identify three forms of adsorbed acetic acid: bidentate acetates and two forms of molecularly adsorbed acetic acid (1645–1653 and 1700–1720 cm–1). Rate constants for the consumption of two forms of molecularly adsorbed acetic acid, which are equal to 0.029 and 0.02 s–1, respectively, were found to be close to the rate constant of the catalytic reaction equal to 0.034 s–1, which was measured at T = 200 °С. It was concluded that two forms of molecularly adsorbed acetic acid serve as the key intermediates in the hydrogenation of acetic acid over Pt-ReOx/TiO2 catalyst.

Diesel vehicles are responsible for the emission of not only soot and NОx to the environment, but also various organic and inorganic toxic compounds. The review provides a detailed discussion of the place of oxidation catalyst in the modern system for purification of exhaust gases from diesel engines, the ways to improve and optimize the oxidation catalysts intended for the neutralization of carbon monoxide and hydrocarbons according to the accepted standards, and the methods for decreasing the content of Pt group metals in the indicated catalytic systems.

The review analyzes state of the art in the partial oxidation of alcohols to carbonyl compounds over Ag catalysts, including the partial oxidation of methanol to formaldehyde, oxidation of ethylene glycol to glyoxal, and oxidation of ethanol to acetaldehyde. For the methanol oxidation process, conditions for implementing the BASF and ICI technologies are considered and the entire chain of transformations from natural gas to formaldehyde is estimated in terms of exergy. When considering modern kinetic studies for the partial oxidation of alcohols on silver, some recent publication are analyzed, particularly those devoted to the application of a ring-shaped reactor to suppress the homogeneous steps of formaldehyde decomposition, the development of a new approach to simulation of the process taking into account different reactivity of the catalyst, and the creation of a simulator to calculate the methanol oxidation process using a neural network with a genetic algorithm. Main steps in the development of a technology for the partial oxidation of ethylene glycol to glyoxal on Ag catalysts are briefly described. The author analyzes modern experimental and theoretical works devoted to the formation mechanisms of oxygencontaining active sites on the silver surface and their involvement in the conversion of alcohols to carbonyl compounds, as well as the new Ag-containing catalytic compositions.

The paper considers the problem of collecting solid particles in the production line with dehydrogenation of С4–С5 isoparaffins to isoolefins in a fluidized catalyst bed. The collecting of finely dispersed catalyst particles for dehydrogenation of paraffin hydrocarbons using a standard CN-15 cyclone and a new dust-collecting device (NDD) with arched elements was studied. The results of numerical simulation of CN-15 and NDD are reported. A comparative study revealed that NDD is more efficient than CN-15 in collecting the finely dispersed solid particles with the size below 20 μm. For NDD, determinate variations in the pressure and rate profiles, without any critical deviations, were observed. The gas flow rate through the arched elements of NDD was found to be stable, in distinction to CN-15, where high rates appear at the cyclone edges, thus raising the probability of dust breakthrough into the flow to be purified.

The paper presents the results of studying the iron-potassium catalysts for dehydrogenation of ethylbenzene (EB) to styrene, both fresh and spent, under industrial conditions: Cat-1 (imported), Cat-2 and Cat-3 (domestic). The initial samples are the multiphase systems consisting of potassium ferrites, hematite and cerianite (CeO2). After two years of operation, the phase composition of the catalysts was represented mostly by magnetite and cerianite, and potassium (K+) content in Cat-1, Cat-2 and Cat-3 samples decreased by 40, 20 and 26 %, respectively. Therewith, the Cat-2 sample retained a uniform K+ distribution in the spent catalyst grain. According to XRD data, the coherent scattering region (CSR) of CeO2 crystals in this sample did not change significantly. In the Cat-3 sample, the CSR size of CeO2 crystals decreased from 302 to 110 Å, while in Cat-1 it increased from 284 to 419 Å. After a two-year operation, the highest EB conversion equal to 72.1 % was observed on the Cat-2 sample, whereas on Cat-3 it decreased from 72.3 to 57.4 %. A 6÷11-fold decrease in the crushing strength was found for the spent samples, which made them unsuitable for further application.

The paper systematizes the experience of the interaction with petrochemical and oil refining industrial organizations for implementation of research results. An important role of cooperation and interdisciplinary studies is noted, the specificity of the interaction with consumers and producers of catalysts is considered. The most essential steps in the development and introduction of catalysts are distinguished.
