Supported ionic liquid phase (SILP) catalysts for ambient pressure and ultra-low temperature water-gas-shift reaction |
| 초록 |
Supported ionic liquid phase (SILP) catalysts are new materials consisting of an ionic liquid, a metal catalyst and a porous support. The catalyst is dissolved in the ionic l iquid which itself is dispersed as a thin film on the inorganic support, thus bridging the gap between traditional homogeneous and heterogeneous catalysis. Especially continuous, gas-phase reactions are highly suited for this novel and innovative technology. An industrially important example is the water gas shift (WGS) reaction, by which hydrogen can be genera ed from carbon monoxide and water. Homogeneous WGS catalysts could operate at milder temperat res than commercial heterogeneous systems but for continuous operation the use of liquids is disadvantageous. Since hydrogen production via WGS is an exothermic reaction, lower temperatures result in higher equilibrium conversions and we therefore investigated a series of homogeneous catalyst complexes immobilized in SILP systems. The investigated SILP systems exhibit activities and stabilities exceeding those of homogenous systems reported in literature. Even co mmercially available WGS catalysts are outperformed, indicating that SILP derived WGS catallysts may become a promising alternative to conventional heterogeneous systems. |
