| titleOfInvention | It is a kind of to couple difunctional Au-based catalyst and its preparation method and application |
| abstract | The present invention provides a kind of difunctional Au-based catalysts of coupling, include modified metal-oxide matrix and micro porous molecular sieve, and be supported on the gold on described matrix surface.Gold in the difunctional Au-based catalyst of coupling of the present invention is elemental gold, high price gold ion will not be made to be reduced during catalyzing acetylene hydrochlorination, can be avoided the phenomenon that active group reunion inactivates and then influences the catalytic stability of catalyst.The catalyzing acetylene hydrochlorination production vinyl chloride provided by the present application for coupling difunctional Au-based catalyst can be stable, from embodiment result, the high conversion rate of acetylene is in 92%, the selectivity of polyethylene is greater than 99.8%, and the stability in use of the difunctional Au-based catalyst of coupling is very high, and it is unchanged to be able to maintain catalytic performance in 600h.It is easy to operate the present invention also provides the preparation method of the difunctional Au-based catalyst of coupling, it is easy to implement. |
