| Abstract: | The catalytic properties of X, Y, ZSM-5 and SBA zeolites, various sulphates, phosphates and their composite catalysts were investigated respectively using acrylic acid dehydration as model reactions. The results indicated that catalytic activities of the catalysts were better by adjusting the acidity alkalinity of the zeolites and using composite catalyst which consisted of 13X zeolite and sulphate. The total selectivity to methyl acrylate and acrylic acid reached 80.3% over the composite catalyst under optimum reaction condition. |
