in the present study, the effects of calcium doping on the performance of the co-precipitated cu-mgo catalysts prepared with different calcium loadings in the selective hydrogenation of furfuraldehyde were investigated. the results proved that the addition of this promoter had a remarkable impact on the catalytic performance. the conversion of furfuraldehyde enhanced up to 83% and the furfuryl ...

Composite magnetic catalysts containing different amounts of sulfated titania (33–50 wt %) have been prepared by means high energy ball-milling between TiO2 and NiFe2O4. The characterized with N2 adsorption/desorption isotherms, XRD, temperature programmed oxidation (TPO) vibrating sample magnetometer (VSM). catalytic activity was measured in the reaction aniline 4-phenylbutyric acid continuous...

Abstract This paper deals with reactor design, modeling, and simulation of a pilot-scale reverse flow operation used for catalytic oxidation lean benzene-air mixtures. The was designed conducting benzene adiabatic temperature rise less than 54°C. According to the rule thumb, this kind condition requires reaction be accomplished under operation. In some criteria were calculated such as Mears, We...

In this work, a novel strategy of the use dielectric barrier discharge (DBD) plasma-catalysis for exothermic reactions is presented. DBD-plasma used as reaction ignitor, rather than classical approach continuous operation, by taking advantage synergy between catalytic plasma activation from room temperature and self-sustained reaction. CO2 methanation was performed in thermal insulated reactor ...

This thesis describes efforts made on the development of an existing catalytic incinerator. The development work, called process characterization, consists of four general parts. These are the development of measurement methodology, the studying of construction materials, the selection of suitable catalysts and the testing of the effects of process operation conditions. The two application area...

in this study the efficacy of intermittent and continuous drying processes on fissuring of hashemi and koohsar varieties was investigated. the fissuring of the kernels was assessed based on stress cracking index (sci). the experiments were carried out at drying and tempering temperatures of 30, 45 and 60 °c, drying durations of 20, 40 and 60 min, and constant tempering duration of 80 min. in co...

Development of solid oxide fuel cell (SOFC) anode with high resistance to coking and sulfur poisoning is highly desirable for the direct application natural gas in SOFC. Herein, a (Cu, Sm)CeO2 anchored Cu nanoparticles has been prepared. Most particle size ranges from 20 50 nm, which can increase conductivity catalytic activity anode. The Cu/CSCO10 supported exhibits maximum power density 404.6...
