A process for producing propylene involves dehydration of isopropanol. The dehydration process includes a step of subjecting a starting material containing isopropanol to a dehydration reaction in the presence of a dehydration catalyst comprising alumina to produce a product containing propylene. The starting material has a water content of 0.1 to 10.0 wt % (relative to 100 wt % of the total mass of the starting material), and the product has a total content of C2 unsaturated impurities and C3-C4 unsaturated impurities of 80 ppm or less (relative to 100 wt % of the total mass of the product).

Preparation method and production device for propylene

A silicon-containing alumina support, a process for preparing the support, and a catalyst containing the support are provided. The alumina support includes an additive silicon enriched on its surface, with the difference between the atomic ratio of silicon to aluminum on the surface of alumina support and that of the alumina support is at least 0.10. The process for preparing the silicon-containing alumina support comprises adding a nanometer silicon compound. The inventive alumina support can be used in manufacturing a catalyst for hydrotreating hydrocarbons with good physico-chemical properties and performance.
