The 250 kW TRIGA Mark II research reactor of the Jožef Stefan Institute (JSI) has been in operation since 1966. The reactor went critical on 30 May 1966. It is a light water reactor, with solid fuel elements in which the zirconium hydride moderator is homogeneously distributed between enriched uranium. The reactor core consists of about 70 fuel elements, which are arranged in an annular lattice...

Bagasse as a real biomass was converted to hydrogen rich gas via catalytic supercritical water gasification process. To find the effect of Cu on selectivity of products, Cu promoted Ni-γAl2O3 catalysts were prepared with 1 to 20wt% Ni and 0.5 to 10wt% Cu loadings via impregnation method. Catalysts were characterized by ICP, BET, XRD, H2 chemisorption and TEM technique as well CHNS analysis was ...

A batch reactor may be combined directly with a distillation column by distilling off the light component product in order to increase the reactor temperature or to improve the product yield of an equilibrium reaction. The same amount of the light product should be removed as the amount being formed by the reaction at any time. A linearized model has been developed which describes the process b...

Double-skin sheet reactor (DSSR) attracts attention in recent years due to the simple design and high mass transfer, but its application to photocatalytic CO2 reduction with immobilized catalyst is still a new trial. In this paper, the three-dimensional models describing the photocatalytic CO2 reduction in DSSR by means of solar energy were developed and numerically simulated, on the basis of t...

Approach • Complete reverse kinetics and Computational Fluid Dynamics (CFD) modeling to optimize reactor geometry for forward reactions • Measure forward kinetics in quartz & Inconel reactors to determine reactor wall catalysis • Measure forward kinetics in reactor packed with membrane material to determine catalytic activity • Measure membrane H2 permeability in presence of clean syngas compon...

This article presents the results of a techno-economic analysis repowering coal-fired power plant’s steam turbine system to instead accept heat produced by pressurized water reactor-type small modular nuclear (PWR SMR). type challenge due significantly lower pressure and temperature system. A 460 MW supercritical unit with parameters 28 MPa/560 °C/580 °C, operated in Łagisza Power Plant Poland,...
