Method and system for converting ultrahigh-temperature waste into hydrogen oil

Abstract

The invention discloses a method and system for producing hydrogen oil by converting ultrahigh-temperature waste, and the system provided by the invention is used for gasifying waste at ultrahigh temperature to generate mixed gas, and the mixed gas is subjected to reforming and water-gas shift under the action of a high-selectivity reaction catalyst to generate hydrogen and carbon dioxide. Hydrogen passes through a gas purification section to prepare purified hydrogen, and the purified hydrogen and the liquid organic hydrogen storage carrier are subjected to hydrogenation reaction to obtain hydrogen oil which can be stored at normal temperature and normal pressure. According to the system for converting the ultrahigh-temperature waste into the hydrogen oil, various pollution sources generated in the waste treatment process can be fundamentally eradicated, the requirements of all environmental protection standards in the world at present are met, the waste can be converted into hydrogen energy and various useful substances, and good environmental protection and economic values are achieved.

Description

technical field [0001] The invention belongs to the technical field of hydrogen energy, and in particular relates to a method for converting ultra-high temperature waste into hydrogen oil. Background technique [0002] With the rapid development of my country's social economy, the acceleration of urbanization and the rapid improvement of people's living standards, the discharge of waste has increased year by year, and waste has become an urgent pollution problem that needs to be solved in urban development. Waste includes urban waste, industrial garbage and biomass. Biomass includes all plants, microorganisms, animals that feed on plants and microorganisms, and their wastes. [0003] Urban waste is mainly organic waste and five types of domestic plastic waste (polyolefin, polyvinyl chloride, polystyrene, phenolic plastic, aminoplast), and the treatment of urban waste in the prior art mainly includes landfill or waste incineration for power generation. Landfills occupy a lar...

Problems solved by technology

Taking Germany as an example, the liquid organic hydrogen storage technology developed can realize the hydrogen absorption and desorption cycle under relatively mild conditions, but the released hydrogen contains by-product gases that are poisonous to fuel cells, and there are also important problems such as low capacity and inconvenient use. Defects: Japan is currently developing hydrogen storage technology based on traditional organic materials such as toluene, but the dehydrogenation temperature is too high (greater than 300°C), and there is also the problem of poisoning fuel cells by by-products

Therefore, the large-scale application of these two normal temperature and pressure liquid organic hydrogen storage technologies is restricted.
