The effect of free fatty acid on the reactivity of copper-based catalysts for the hydrogenolysis of fatty acid methyl esters

Autor: Guido U-A Sai, L.H. Staal, Frank Th. van de Scheur, Alfred Bliek

Publikováno v: Journal of the American Oil Chemists' Society, 72(9). Springer Verlag

In the synthesis of fatty alcohols by hydrogenolysis of fatty acid methyl esters, small amounts of free fatty acids in the feed negatively affect the reactivity of copper-silica based catalysts. The effect of the acid was investigated in relation to

Activity-enhanced copper-zinc based catalysts for the hydrogenolysis of esters

Autor: D. S. Brands, Christian Oude Luttikhuis, Bart van der Linden, E.K. Poels, L.H. Staal, Frank Th. van de Scheur

Publikováno v: Applied Catalysis A-General, 116, 237-257. Elsevier

For silica-supported copper-zinc catalysts, a fivefold enhancement of the activity in the hydrogenolysis of methyl acetate has been obtained by high-temperature reductions in the range between 550 K and 700 K. Furthermore, simultaneously, the selecti

Effects of zinc addition to silica supported copper catalysts for the hydrogenolysis of esters

Autor: L.H. Staal, Frank Th. van de Scheur

Publikováno v: Applied Catalysis A: General. 108:63-83

When using silica supported copper-zinc oxide catalysts in the hydrogenolysis of methyl acetate, a profound effect of zinc on the activity and selectivity of the catalysts has been observed. The activity and selectivity improve with increasing zinc c

Structure-activity relation and ethane formation in the hydrogenolysis of methyl acetate on silica supported copper catalysts

Autor: F.T. van de Scheur, B. van der Linden, L.H. Staal, M.C. Mittelmeijer-Hazeleger, J.G. Nazloomian

Publikováno v: Applied Catalysis A-General, 111, 63-67. Elsevier

The activity and selectivity of silica-supported copper catalysts in the hydrogenolysis of methyl acetate were studied in relation to the structure of the active phase. The activity was found independent of the copper loading, when the weight of copp

Design and Preparation of Vanadium Resistant FCC Catalysts

Autor: A.P. Chapple, K. Gosling, D.J. Rawlence, L.H. Staal

Summary The addition of primary distillation residues to the FCC feedstock leads to increased vanadium loadings on the catalyst and major problems with catalyst deactivation. The deactivation process is believed to involve the formation of low meltin

Diazabutadienes as σ,π-bridging ligands in binuclear molybdenum carbonyl complexes containing molybdenummolybdenum double bonds

Autor: Kees Vrieze, Ad Oskam, L.H. Staal

Publikováno v: Journal of Organometallic Chemistry. 145:C7-C10

Reduction of Mo(CO)4 DAB (DAB = diazabutadiene) followed by oxidation with Mn(CO)3BrDAB or HCl gives a small yield (15 to 25%) of complexes of the type Mo2(CO)6(DAB)2, in which the two DAB ligands bridge a molybdenummolybdenum double bond and act
