Co-Torrefaction Progress of Biomass Residue/Waste Obtained for High-Value Bio-Solid Products

open access: yesEnergies, 2022
The co-torrefaction of several biomasses may be a viable solution in the study area, as it produces biofuels and addresses waste-treatment concerns. This review evaluates biomass through ultimate, proximate, and FTIR analyses, and the mechanism of the co-

Monolitni katalizatori i reaktori: osnovne značajke, priprava i primjena (Monolith catalysts and reactors: preparation and applications) [PDF]

open access: yesKemija u Industriji, 2004
Monolithic (honeycomb) catalysts are continuous unitary structures containing many narrow, parallel and usually straight channels (or passages). Catalytically active components are dispersed uniformly over the whole porous ceramic monolith structure (so ...

Neutron capture cross section and capture gamma-ray spectra of 138Ba in the keV-neutron energy region

open access: yesEPJ Web of Conferences, 2015
The neutron capture cross sections and the capture γ-ray spectra of 138Ba were measured in the astrophysically important energy region. Measurements were made at neutron energies from 15 to 80 keV.

Interfacial Heat Transfer of Condensation Bubble with Consideration of Bubble Number Distribution in Subcooled Flow Boiling

open access: yesJournal of Thermal Science and Technology, 2013
For predicting the void fraction distribution in subcooled flow boiling, it is necessary to measure the interfacial heat transfer coefficient—which determines the amount of condensation rate of vapor bubble—with high accuracy.

Chemical Looping Combustion: A Brief Overview

open access: yesEnergies, 2022
The current development of chemical looping combustion (CLC) technology is presented in this paper. This technique of energy conversion enables burning of hydrocarbon fuels with dramatically reduced CO2 emission into the atmosphere, since the inherent ...

Neutron capture cross section and capture gamma-ray spectra of 89Y

open access: yesEPJ Web of Conferences, 2016
The neutron capture cross section of 89Y was measured by the time-of-flight method in an energy range from 15 to 100 keV. A pulse-height weighting technique was applied to derive the capture yield.

Testing of the ABBN-RF multigroup data library in photon transport calculations

open access: yesEPJ Web of Conferences, 2017
Gamma radiation is produced via both of nuclear fuel and shield materials. Photon interaction is known with appropriate accuracy, but secondary gamma ray production known much less. The purpose of this work is studying secondary gamma ray production data
