In the presented review the results of studies devoted to the selective hydrogenation of acetylene to ethylene over bimetallic palladium-containing catalysts are systematized. General regularities and peculiarities of the catalysts action in gas-phase hydrogenation of traces of acetylene in the acetylene-ethylene mixture obtained by pyrolysis of petroleum raw materials, as well as in the process of liquid-phase hydrogenation of mixtures enriched with acetylene and hydrogen are analyzed.

Resumen
Primary Australian terrestrially-derived crudes are characterised by high wax and n-alkane contents. These characteristics, as determined by hydrogenation and hydrous pyrolysis, appear to be unrelated to either the chemical or petrographic compositions of Victorian brown coal lithotypes. Furthermore, since relationships between chemical and petrographic composition are obscure, a re-examination of current concepts which relate these established source rock parameters to liquid hydrocarbon generating potentials is warranted.The content of thermally stable, longer-chain, n-alkyl components in so

The petroleum ether-insoluble fraction of Dagang vacuum residue (DVR-PEIF) was subject to catalytic hydrogenation in the presence of Y zeolite. Most of compounds detected with GC/MS in the PE-soluble fraction of products from DVR-PEIF are saturated hydrocarbons, including chain alkanes and cyclanes.

Analysis of the dependence of the softening point on the mesophase content for the obtained samples showed that at the same mesophase content, decantoil pitches exhibit a lower softening point compared to pyrolysis resin pitches, for which, even at 30 % mesophase, the softening point approaches 300°C.

Resumen
A novel near-zero-emission process for obtaining clean middle-distillate fuels, primarily from coal and with some algal input, has been developed. This process involves the solvent extraction of coal, followed by two stages of hydrotreating and hydrogenation, and finally distillation, to produce fuels of very low sulfur and low aromatics content. Prototype fuels have been shown to provide performance comparable to petroleum-derived jet and diesel fuels in gas turbine and small diesel engines, as well as in the solid oxide fuel cell.

Indonesia has been facing an energy security issue regarding Liquefied Petroleum Gas (LPG) consumption. The rapid increase of LPG consumption and huge import have driven the Indonesian government to develop the alternative for LPG in the household sector. Dimethyl ether (DME) is the well-fit candidate to substitute LPG because of its properties similarities. However, discrepancies in the properties, such as combustion enthalpy and corrosivity, lead to adjustments in the application. Coal is a potential raw material to produce DME, especially in Indonesia, known as the fourth-largest coal produ

Mesoporous ZSM-5 zeolite is developed to enhance the catalytic performance in a hydrocracking reaction. The generated mesopores and mesoporous channels in the new catalyst supply more opportunities for reactant accessing the active sites according to the better mass transfer and diffusion. Meanwhile, the acidity of the mesoporous catalyst is also weakened because of the removal of Si and Al species from its MFI structure, which makes the products distribution drift to more valued chemicals such as olefins.

Resumen
Fischer-Tropsch synthesis (FTS) offers the potential to produce high-value transportation fuels or petrochemicals from biomass (``2nd generation biofuels"). Primary synthesis products contain mainly n-alkanes and n-alkenes, ranging from methane to high molecular weight waxes. Bifunctional catalysts, as used in petroleum refining, are capable of modifying hydrocarbon molecules. They are characterized by the presence of acidic sites, which provide the hydrocracking and isomerization functions, as well as metal sites, which provide hydro-/dehydrogenation functions, and thus avoid the formation of

Resumen
Platinum group metals are widely used as a hydrogenating-dehydrogenating component of a number of petroleum refining and petrochemical catalysts, in particular for isomerization of linear alkanes. The main direction in improving the preparation of these catalysts is to reduce their cost by optimizing the metal component amount. However, insufficient attention was paid to the method of introduction of an active metal into the carrier; at the same time, this issue is especially important in case of zeolite catalysts, for which ion exchange can be used in addition to traditional impregnation.
