Activated carbon supported silicotungstic acid catalysts for ethyl-tert-butyl ether synthesis
Vapor phase ethyl‐tert‐butyl ether (ETBE) production was conducted in the presence of Cesium salts of silicotungstic acid (Cs‐STA), activated carbon supported silicotungstic acid (AC‐STA), and activated carbon supported Cesium salts of silicotungstic acid (AC‐Cs‐STA) catalysts. Isobutene (IB) conver...

| description | Vapor phase ethyl‐tert‐butyl ether (ETBE) production was conducted in the presence of Cesium salts of silicotungstic acid (Cs‐STA), activated carbon supported silicotungstic acid (AC‐STA), and activated carbon supported Cesium salts of silicotungstic acid (AC‐Cs‐STA) catalysts. Isobutene (IB) conversion to ETBE at 373 K were determined as 0.16 and 0.2 for STA and AC‐STA catalysts on constant space time basis. This increase of activity is one of the highlights of this study considering that STA loading in AC‐STA catalysts had been adjusted to 40%. IB conversion to ETBE obtained at 373 K in the presence of AC‐STA catalyst was found to be close to equilibrium. Stability of the synthesized catalysts were tested by applying a washing procedure with ethanol. Repeated ETBE synthesis with thoroughly washed samples indicated quite stable and active catalyts. © 2011 American Institute of Chemical Engineers AIChE J, 2011 |
