Partial Oxidation of Ethanol Using VOx/SBA-15 and VOx/Fumed Silica Catalysts in a Bench-scale Stainless Steel Reactor

Abstract

Two VOx/SBA-15 catalysts and three VOx/SiO2-fumed silica, with 5, 10 and 1, 5, 10 %wt. vanadium content respectively, were tested in a stainless steel continuous flow reactor for the partial oxidation of ethanol. The catalysts were tested at 150 – 300 °C. Products were analyzed by GC-FID, GC-OFID and GC-MS. The aim was exploring the problematics which could be found when more industrial close conditions are used. The total conversion of ethanol and selectivity to acetaldehyde were different than the expected ones. For VOx/SiO2-fumed silica, the total conversion was higher with a lower selectivity to acetaldehyde compared to VOx/SBA-15 catalysts.

Activity, Selectivity and Initial Degradation of Iron Molybdate in the Oxidative Dehydrogenation of Ethanol

“…Due to this attractiveness, different catalyst systems have been studied for ethanol ODH. The main classes of investigated catalysts are supported metal oxides, mainly supported VO x , [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24] mixed metal oxides, [25,26] supported metal catalysts [27][28][29][30] or carbon-based catalysts. [31][32][33] Supported vanadium oxide catalysts show high activity in the ODH of ethanol.…”
