Abstract
One-step CO2 conversion to liquid hydrocarbons (Emission-to-Liquid) was carried out at 340°C and 10.0 MPa in the presence of tandem catalyst. This catalyst consisted of two components loaded in a layered manner: a copper–zinc oxide component responsible for the synthesis of methanol from CO2, and a zeolite component responsible for the conversion of methanol to liquid hydrocarbons. The structural effects of the zeolite component (Hybrid Intergrowth Structure Zeolites) on the yield and hydrocarbon composition of the liquid product were investigated. The textural properties of the zeolite component were found to be critical to the hydrocarbon composition of the liquid product. Hybrid co-crystalline structures, namely MFI–MEL and MFI–MCM-41, with their large volume of mesopores, significantly enhanced the content of aromatics in the liquid hydrocarbon product. This was achieved not only due to the reduced diffusion limitations for product removal from the zeolite pores but also due to the activation of secondary aromatization reactions in the catalyst mesopores.

Abstract
This review provides an analysis of prior research on liquid-media methane pyrolysis for hydrogen production. It discusses the experimental studies and reported data on methane pyrolysis in molten metals, molten binary alloys, molten salts, and molten metal–salt media. The experimental data suggest that binary metal alloys are superior to pure metals in terms of catalytic performance. A comparative assessment of catalytic activity showed that the highest performance (methane conversion above 95% at temperatures below 1200°C) has been achieved by molten Ni–Bi and Cu–Bi alloys. Besides the thermobaric conditions and characteristics of the bubbling systems, the media’s reactivity plays a key role in pyrolysis efficiency. The combined use of molten metals and salts as a reaction medium noticeably enhances the methane conversion (due to the catalytic activity of molten metals) and appreciably reduces the content of metal impurities in the carbon product.

Abstract
Double metal cyanide (DMC) catalysts have no alternatives for use in the industrial process of propylene oxide (PO) polymerization to obtain polypropylene oxide (PPO) with the properties required for specialty applications: low degree of unsaturation, high molecular mass, and high hydroxyl value. The modern commercial samples show high performance and allow the process to be performed with extremely low catalyst amounts (down to 25 ppm). Such amounts do not require the catalyst regeneration and to not impair the polymer properties. The main drawbacks of these materials are relatively complex synthesis and moisture sensitivity. Despite the fact that DMC catalysts are known since the 1960s, their hybrid character and variable composition still complicate their study and elucidation of the relationship between the preparation procedure, composition, and properties of these materials. This review is aimed at systematizing and analyzing the information on the synthesis, structure, and action mechanism of DMC catalysts. Both traditional synthesis and nontraditional methods for preparing DMC catalysts are described in detail. Much attention is paid to the catalytic site structure, polymerization mechanism, and physicochemical properties of these materials as heterogeneous catalysts.

Abstract
The dynamics of the silicon sorption on the NiMo/Al2O3 guard-bed catalyst containing ~2.0 wt % Ni and ~6.0 wt % Mo during hydrotreating of diesel was studied. The catalyst bed was divided into five equal sections separated by perforated metal partitions permeable to the feed. Four series of experiments were performed; their time was varied in the range 48–200 h, and the temperature was 340°C. A diesel fraction containing ~1.0 wt % sulfur, 130 ppm nitrogen, and 200 ppm silicon introduced in the form of decamethylcyclopentasiloxane was used as the feed. The specific surface area of all the spent samples was 170–190 m2/g, the pore volume was 0.35– 0.43 cm3/g, and the average pore diameter was 8–9 nm. The sorption on a catalyst grain 2.5 mm in diameter is diffusion-controlled. The effective mass transfer coefficient and the catalyst capacity under the experimental conditions (5 wt %) were estimated using the equation describing the sorption process.

Abstract
The paraffin–naphthenic fractions (with boiling points below 310°C) prepared from three high-viscosity naphthenic crude oils, classified as types B1 and B2 (according to Petrov’s classification), were subjected to thiocarbamide complexation. The molecular composition of polycyclic hydrocarbon biomarkers and C11–C13 adamantanes in the oil samples suggested a predominantly marine genotype of the precursor organic matter (OM). The molecular composition also suggested source rocks of a clayey type. Nonetheless, the biomarkers detected in one sample indicated some contribution of terrigenous components to the precursor OM. All the oils were generated under the conditions of the main oil generation zone and, presumably, underwent microbial transformations in the deposits. The compositions of C10–C14 adamantanes in the initial paraffin–naphthenic fraction, in the thiocarbamide adduct, and in the filtrate that remained after the adduction were comparatively characterized for each oil sample. The test conditions allowed us to have adamantane more than 100-fold concentrated (in the adduct), to quantify it in the oils, and to evaluate the concentrations of C11–C14 alkyladamantanes in the oils using adamantane as an internal standard. C10–C14 adamantanes exhibited selective adduction ability, with the extraction ratios of individual components being different. Taking into account these extraction ratios, the component concentrations were evaluated on crude oil basis: 2.7 to 7.6×10–3 wt % for adamantane and 87 to 267×10–3 wt % for total C10–C14 adamantanes. The identification of adamantanes in the initial paraffin–naphthenic fractions, adducts, and filtrates revealed the presence of some other tricyclanes (probable precursors of alkyladamantanes) as well as decaline homologues. Like adamantanes, these compounds exhibited selective ability to complex with thiocarbamide.

Abstract
A series of CeO2–MgO catalysts with different molar ratio was prepared for the plasma-activated CO2 decomposition to CO and O2. The catalysts were synthesized by the sol-gel method and characterized by physicochemical methods (XRD, SEM, XPS, low-temperature N2 adsorption, CO2-TPD). The highest CO2 conversion (31%) was achieved in the presence of the catalyst with the highest CeO2 content. The addition of H2 into a CO2 decomposition system was also studied. No CO2 methanation occurred in the presence of synthesized catalysts, though an increase in the CO2-to-CO conversion was observed due to an increase of a discharge power in the presence of molecular hydrogen.
摘要 制备了一系列不同摩尔比的 CeO2-MgO 催化剂，用于等离子体活化 CO2 分解为 CO 和 O2。催化剂采用溶胶-凝胶法合成，并通过物理化学方法（XRD、SEM、XPS、低温 N2 吸附、CO2-TPD）进行表征。在 CeO2 含量最高的催化剂存在下，二氧化碳转化率最高（31%）。还研究了在二氧化碳分解体系中加入 H2 的情况。在合成催化剂存在的情况下，没有发生 CO2 甲烷化，但由于分子氢存在时放电功率增加，观察到 CO2 到 CO 的转化率增加。

Abstract
The study investigates the hydrodecyclization of decalin over zeolite catalysts. The synthesized catalysts were characterized using a combination of physicochemical methods, such as TEM, SEM, low-temperature nitrogen adsorption/desorption, and XPS. The zeolite structure was found to have a major effect on the hydrodecyclization process. This process involves the isomerization of one ring followed by the opening of that ring. Incorporating iridium into the catalysts promoted the production of branched hydrocarbons. When testing the process in the temperature range of 300–400°C and at an initial hydrogen pressure of 50 atm, the Ir/BEA catalyst exhibited the highest activity: at 350°C the decyclization of decalin exceeded 50%.
