The processes of hydrocarbon conversion using catalytic systems

Abstract

This article describes properties of the catalytic conversion of methane to synthesis gas, makes a review of information on the chemical composition of catalysts and provides assumptions about the mechanism of their action. The facts and generalizations given in the article can be useful in determining ways to improve catalytic systems. The most active and most selective catalytic systems make it possible to optimize existing processes by cutting down energy consumption, cost, emissions and increasing the yield of a valuable product. Increasing the depth of conversion and the integrated use of raw materials, as well as ensuring the environmental cleanliness of the technological processes of processing is achieved by using highly efficient catalysts. With the help of highly efficient catalysts it is probable to increase the depth of conversion, the integrated use of raw materials as well as ensuring the environmental cleanliness of the technological processes of its processing.

New Opportunities for the Digital Economy: the Implementation of an Effective State Innovation Policy

“…To make it happen, not in words, but in reality, digital technologies must "serve" the entire society, but not its individual groups, estates, and clans. It is clear that the solution of economic problems with the help of digital technologies cannot by itself eliminate the disproportion of economic development, that is, to harmonize socially necessary needs and production possibilities (20)(21)(22)(23)(24)(25). But information technologies are able to create technological support for solving targets.…”

Technological Typomorphic Associations in Caustobiolites and Methods of Their Extraction

“…The Yaregskiy oil was selected to study the possibility of extracting heavy metals from heavy oil. This oil belongs to the class of heavy (0.945 g/cm 3 ), high-viscosity (10,000-12,000 mPa•s at an initial temperature of 8 • C), low-sulfur and low-paraffin, and it contains a significant amount of heavy metals, e.g., vanadium, nickel, iron, titanium, noble and rare-earth metals [12][13][14][15][16][17][18][19][20][21][22][23]. The analysis of the initial sample and separation products was performed by atomic absorption, X-ray fluorescence, mass spectrometry with inductively coupled plasma, and instrumental neutron activation analysis (INAA) (St. Petersburg Konstantinov Institute of Nuclear Physics.…”

“…Previous studies show that some metals accumulate in large amounts in a number of cases compared to their clusters in the lithosphere. This allows us to estimate the economic and technological feasibility of these metals extraction from oil, while improving the quality of basic petroleum products [12][13][14][15][16][17][18][19][20].…”

Comparison of novel Ni doped exsolution perovskites as methane dry reforming catalysts

“…Studies of different metal catalysts for MDR have shown that noble metals such as Ru, Pd, Rh, Pt and Ir show a high catalytic activity [3,4]. A cheaper alternative to noble metals is the use of Nickel based catalysts, specifically systems that form catalytically active Nickel particles in reaction conditions such as Ni-doped Perovskites [5].…”
