SYNTHESIS OF NEW CATALYSTS BY INSERTION OF Co AND Cu IN THE MATRIX OF HYDROTALCITE-LIKE MATERIALS FOR CINNAMALDEHYDE HYDROGENATION
Environmental Engineering and Management Journal › Vol. 10 › Nr. 10 Abstract:This study is focused on the influence of Co and Cu ions located in Zn/Ni/Al matrix on the structural, textural and catalyticproperties of layered double hydroxides (LDHs). The samples were prepared by co-precipitation (Ni2+/Co2+(Cu2+)=0.25;M2+/M3+=2)) at low super-saturation and afterwards characterized by XRD, nitrogen physisorption, thermogravimetry, FT-IR, DRUV-Vis and TPR. The XRD results show that the resulted solids are well crystallized and contain only pure phases of LDHs.Also,...

CONTROLLING THE ACTIVITY AND CHEMOSELECTIVITY IN THE CINNAMALDEHYDE HYDROGENATION BY INSERTION OF NONNOBLE METALS IN THE MATRIX OF HYDROALCITE-LIKE MATERIALS
Environmental Engineering and Management Journal › Vol. 11 › Nr. 1 The purpose of this study was to prepare new nanocomposite catalysts of Metal/LDHs type by mild reduction of transition metal cations Co2+ and Cu2+ substituted in the matrix of ZnAl-LDH at 150°C and atmospheric pressure, under hydrogen flow. To this end, a series of ZnCuCoAl layered double hydroxides (LDH) precursors were synthesized by co-precipitation method. M2+/M3+ (i.e., Zn2+/Al3+) molar ratios were kept constant while the Cu2+/Co2+ molar ratios were varied in order to investigate their in...

THE ROLE OF GREEN CHEMISTRY IN BIOMASS PROCESSING
Environmental Engineering and Management Journal › Vol. 12 › Nr. 3 The book edited by Haibo Xie and NicholasGathergood focuses on one of the most importantscientific issues of the 21 century which is thereplacing fossil fuel with sustainable alternatives suchas biomass. Fossil fuels are conventional rawmaterials for many industrial sectors includingchemical and energy production. Usage of fossil fuelis limited by their availability, price and carbonfootprint. Biomass is a renewable resource globallyavailable, cheaper and carbon sequestering. Step bystep shiftin... Autori: Adrian Catalin Puitel ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=26101
COPPER NANOPARTICLES SUPPORTED ON POLYETHERFUNCTIONALIZED MESOPOROUS SILICA. SYNTHESIS AND APPLICATION AS HYDROGENATION CATALYSTS
Environmental Engineering and Management Journal › Vol. 14 › Nr. 2 Abstract
Copper nanoparticles were successfully synthesized on polyether-functionalized mesoporous silica to investigate the effect of
metal loading (10, 25 and 35 wt. % Cu) on their structural and catalytic properties. The oxide forms of these nanocomposite
materials were thoroughly characterized by nitrogen physisorption, SAXS, WAXS, TEM, EDXS, and TPR, whereas the metallic
forms were analysed by N2O chemisorption. The results indicated that the mesostructured SBA-15-like hybrids favoured ... Autori: Constantin Rudolf ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=26653
NUMERICAL ANALYSIS OF Cu AND Ni BASED CATALYSTS IN THE HYDROGENATION PROCESS OF GLYCEROL
Environmental Engineering and Management Journal › Vol. 14 › Nr. 9 Abstract
The paper describes a numerical analysis concerning the behaviour of Cu and Ni based catalysts having different mole ratios of Ni
to Cu in the process of glycerol hydrogenolysis. The impregnation technique was used to prepare the copper and nickel based
catalysts. Our study revealed that their performances are different and depends on the Ni/Cu ratio. The catalysts were tested using
various reaction conditions, such as time and temperature, and their performances analysed based on t... Autori: Adriana Marinoiu ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=26843
INFLUENCE OF FIREBALL COUPLED WITH A TOXIC PUFF RELEASE ACCIDENT CONDITION ON CONSEQUENCES AND POSSIBLE DOMINO EFFECT OCCURRENCE FOR TWO RISKY NEIGHBORING CHEMICAL PLANTS
Environmental Engineering and Management Journal › Vol. 14 › Nr. 11 Abstract
A study of a classical BLEVE fireball model associated with a toxic Puff release one was made in order to evaluate the influence
of accident conjugate conditions on its consequences in two neighbouring industrial plants. The possible occurrence of the Domino
effect is also exemplified for the approached chemical complex including two sensitive neighbouring chemical plants including
tubular reactors for catalytic oxidation of butane to maleic anhydride and catalytic hydrogenation of ... Autori: Hasan Hadi Salman Khwayyir ISSN: 1843 - 3707 http://www.ecozone.ro/reviste.php?RID=26880 |
