COMBUSTION OF MODEL AND REAL OIL SLUDGE IN A FLUIDIZED BED OF CATALYST

Известия Томского политехнического университета: Инжиниринг георесурсов, 2019
The relevance of the research is caused by generation of a huge amount of oil refinery waste (mainly oil sludge and acid tars). The development of technologies for processing such type of raw materials is an important area for many research teams ...

Magnetic Catalysis in AdS4

, 2012
We study the formation of fermion condensates in Anti de Sitter space. In particular, we describe a novel version of magnetic catalysis that arises for fermions in asymptotically AdS4 geometries which cap off in the infra-red with a hard wall.

Transport catalysis

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 2006
Carrier linked solute transport through biomembranes is analysed with the viewpoint of catalysis. Different from enzymes, in carriers the unchanged substrate induces optimum fit in the transition state. The enhanced intrinsic binding energy pays for the energy required of the global conformation changes, thus decreasing the activation energy barrier ...

Surface Restructuring of Nickel Sulfide Generates Optimally-Coordinated Active Sites for ORR Catalysis

, 2017
First-row transition metal oxides and chalcogenides have been found to rival the performance of precious metal-based catalysts for the interconversion of water and O$_2$.

The thermophysical properties of a promising composite adsorbent based on multi-wall carbon nanotubes for heat storage

Materials for Renewable and Sustainable Energy
The use of energy from alternative energy sources as well as the use of waste heat are key elements of an efficient energetics. Adsorption heat storage is a technology that allows solving such problems.

Theory of laser catalysis with pulses [PDF]

Comments on Modern Physics 2(5), D233 (2001), 2001
The possibility of accelerating molecular reactions by lasers has attracted considerable theoretical and experimental interest. A particular example of laser-modified reaction dynamics is laser catalysis, a process in which the tunneling through a potential barrier is enhanced by transient excitation to a bound electronic state.

Fluorohydration of alkynes via I(I)/I(III) catalysis

Beilstein Journal of Organic Chemistry, 2020
Substrate specificity is ubiquitous in biological catalysis, but less pervasive in the realm of small-molecule catalysis. Herein, we disclose an intriguing example of substrate specificity that was observed whilst exploring catalysis-based routes to ...

How the Chemical Properties of Polysaccharides Make It Possible to Design Various Types of Organic–Inorganic Composites for Catalytic Applications

Molecules
Recently, the use of plant-origin materials has become especially important due to the aggravation of environmental problems and the shortage and high cost of synthetic materials.
