Abstract

The invention provides a metal-doped In2O3 composite material, characterized in that the doped metal is scandium, zirconium or nickel. In the process of preparing propylene from ethanol on the basis of the metal-doped In2O3 material provided by the invention, the material has obvious advantage in propylene selectivity, thereby being capable of improving the efficiency of preparing propylene from ethanol.

Description

technical field [0001] The invention belongs to the field of advanced material preparation, in particular to a metal-doped In 2 o 3 Application of materials in the production of propylene from ethanol. Background technique [0002] In 2 o 3 It is a rare metal material, commonly used in the fields of special materials, metallurgy, and electronic device manufacturing. The present invention finds that the doped In 2 o 3 The material can be applied in the process of synthesizing propylene. [0003] Propylene is a basic chemical raw material widely used in various chemical industrial processes. At present, the production of propylene is obtained from petroleum resources through reaction processes such as naphtha thermal cracking, catalytic cracking, and propane dehydrogenation. These processes are well established and have a wide range of industrial applications. However, the raw materials are all dependent on fossil raw materials which are disposable and non-renewable. ...
