Hydrolysis of Some C,N-Chelated Organotin(IV) Species Used in Catalysis
Švec, P. ; Olejník, R. ; Sajfrtová, Marie ; Padělková, Z. ; Růžička, A.
This work deals with the reactivity of the selected C, N-chelated organotin (IV) species towards cyclohexene oxide, ethylene carbonate, and CO2. Structure of organotin(IV) hydrolytic products isolated from respective reaction mixtures was described.

Monolithic Co-Mn-Al Oxide Catalysts in Total Oxidation of Ethanol
Ludvíková, Jana ; Jirátová, Květa ; Klempa, Jan
We studied preparation of mixed oxide Co-Mn-Al catalysts over cordierite monoliths and examinated their properties in comparison with properties of other catalysts prepared byimpregnation or pelletizing.

Cesium Doped Co-Mn-Al Mixed Oxides in Total Methanol Oxidation
Ludvíková, Jana ; Jirátová, Květa ; Piwowarska, Z. ; Chmielarz, L. ; Jablonska, m.
In this study we focused on both preparations of Co-Mn-Al precursors by mechanochemical treatment of corresponding nitrates and NH4HCO3 and on modification of oxides by doping with cesium. The prepared precursors and catalysts were studied by TGA/DTA, URD, UV-Vis, NH3-TPD and tested in total oxidation of methanol. The results obtained are summarized.

Deposition of Mo and Co Sulfides on Unconventional Silica-alumina Supports for Model Hydrotreating Reactions
Gulková, Daniela ; Kaluža, Luděk ; Zdražil, Miroslav ; Vít, Zdeněk
The mesoporous silica-alumina (SA) was modified by acid leaching which was accompanied with increase of the BET surface area and exposition of strong acidity in cumene cracking and in cyklohexene isomerization. The acid leaching positively affected the activities of the sulfided CoMo catalysts in benzothiophene HDS.

Inhibition of Benzothiophene HDS by Quinoline on PdMo and CoMo/Al2O3 Catalysts
Vít, Zdeněk ; Kaluža, Luděk ; Gulková, Daniela
In this work, the effect of quinoline on benzothiophene HDS was compared with the effect of pyridine on thiophene HDS. This is because benzothiophene and quinoline are closer to practical application.The main goal is to find, if the highrr nitrogen tolerance observed during thiophene reaction occurs also with heavier sulfur and nitrogen molecules. Mo/Al2O3 modified by Pd was selected for this study.

Unconventional Sulfide Hydrotreating Catalysts Prepared by Deposition of MoO3 and CoCO3 with the Assistance of Nitrilotriacetic Acid on ZrO2 Support
Kaluža, Luděk ; Gulková, Daniela ; Vít, Zdeněk ; Zdražil, Miroslav
The most active unconventional hydrotreating CoMo/ZrO2 catalyst was prepared by the impregnation of the support from the solution made by dissolution of MoO3, CoCO3 and nitrilotriacetic acid in water followed by sulfidation without previous calcination.
