Preparation method of metal doped In2O3 composite material

Abstract

The invention provides a preparation method of a metal doped In2O3 composite material. The method comprises the following steps: soaking 100 parts by weight of In2O3 carrier into a two metal doped soluble salt solution for 1 hour, drying at 100-130 DEG C, and then roasting at 450-600 DEG C for 2-5 hours, to obtain the metal doped In2O3 composite material. According to the invention, in the process of preparing propylene from ethyl alcohol based on the metal doped In2O3 material, the material has obvious advantage in propylene selectivity, and can improve the efficiency of preparing propylene from ethyl alcohol.

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. ...
