Abstract

The invention provides an iron-based oxygen carrier preparation method which takes iron and aluminium nitrate as raw materials and urea as fuel, and combines the sol-gel method organically with combustion compound method to prepare nanometer-class Fe2O3 / Al2O3 oxygen carrier with excellent anti-sintering performance. The iron-based oxygen carrier preparation method fully uses the mixing evenness between a plurality of components in the sol-gel method and the reaction process self-maintenance, quickness and low energy-consumption characteristics in the combustion compound method, easily obtains the used oxygen carrier preparation raw material, has the advantages of low price, simple preparation technology and easy operation, and is suitable for scaled mass production of the oxygen carrier.

Description

technical field

[0001] The invention relates to the technical field of nanomaterial preparation, in particular to a method for preparing an iron-based oxygen carrier. Background technique

[0002] Recently, among many environmental problems on the earth, the greenhouse effect and global warming have attracted great attention. While fossil fuels such as coal, oil and natural gas provide more than 85% of the world's energy consumption, a large amount of CO is also produced during the combustion of fossil fuels. 2 , is the CO produced by human activities 2 a major source of . Therefore, the reduction of CO emitted during the combustion of fossil fuels 2 It plays an important role in controlling the greenhouse effect and global warming.

[0003] Chemical looping combustion technology as a new type of fossil fuel CO 2 Emission reduction technology, and existing various CO 2 Compared with the emission reduction technology, it has significant characteristics and advantages, m...
