Abstract

The invention relates to a method for preparing high-purity hydrogen by reforming waste edible grease. The method includes the following steps of firstly, preparing a carrier, wherein metal oxide of a shell-core structure is used as the carrier for conducting reforming hydrogen production on waste edible grease; secondly, preprocessing waste edible grease, wherein swill-cooked dirty oil is deposited and filtered to obtain clear grease liquid; thirdly, making the grease liquid generate high-purity H2 in a fuel reactor through an oxidation-reduction reaction by controlling the circulation speed of particles of the metal oxide carrier and the flow of the grease liquid, and recovering the metal oxide carrier to the initial state to be recycled. Reforming hydrogen production is conducted on waste edible grease through the high-activity and anti-carbon-deposition sintered shell-core double-layer metal oxide carrier, the process is simple, the method is easy to operate and control, and the reaction process can be controlled by only regulating and controlling the temperature of the reactor or the fuel flowing speed.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and energy utilization, and in particular relates to a method for producing high-purity hydrogen by reforming waste edible oil and a device for realizing the method. Background technique [0002] Hydrogen energy is an ideal energy source that is clean, efficient, and free from secondary pollution. It has the advantages of light weight, high calorific value, and convenient transportation. As hydrogen fuel cells are being tried by major automobile companies in the world, the application range of hydrogen energy is increasing. growing. At present, most of the hydrogen in the world comes from the steam reforming or partial oxidation of fossil fuels, and these fossil fuels have disadvantages such as limited reserves, non-renewable, and serious pollution. Therefore, it is of great significance to find an ideal hydrogen source with a large amount, rich sources, and less secondary pollut...
