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.

Embodiment 1

[0043] from Figure 1As can be seen from the flow chart of the method of converting ultra-high temperature medical solid waste into hydrogen oil, the medical solid waste is recovered after the integrated box of collection, storage and transport is first used, and the material is loaded in a closed manner. The integrated box of storage and transfer is a closed cubic box made of metal on four sides and plastic on both sides. Sealing can be carried out by means of negative pressure.

[0044] After the medical solid waste is sealed and compressed, the medical solid waste compressed into pieces is heated, dried and pyrolysis to obtain pre-treated medical solid waste and pyrolysis gas, and the pyrolysis temperature is 800 °C. The pre-treated medical solid waste and pyrolysis gas are gasified at ultra-high temperature, the gasification temperature is 1000 °C, and the gasification process adopts indirect heating to generate a mixture of gas.

Embodiment 2

[0058] After the medical solid waste is recovered by the integrated box of collection, storage and transfer, the closed feeding method is adopted. The integrated box of storage and transfer is a closed cubic box made of metal on four sides and plastic on both sides.

[0059] The medical solid waste is compressed and gasified at ultra-high temperature, the gasification temperature is 1600 °C, and the gasification process adopts indirect heating. Molten slag and gas mixtures are generated.

[0060] Under the action of a highly selective reaction catalyst, the mixture first undergoes a reforming reaction to generate crude syngas, and then hydrogen and carbon dioxide are prepared by the water-gas transformation reaction, and the crude syngas includes CO and H 2 、CO 2 。 The reaction temperature of water-gas conversion is 500 °C. The highly selective reaction catalyst is a supported catalyst with an active component of WO 3 , the carrier is activated carbon.

Abstract

The invention discloses a method and a system for producing hydrogen oil through ultrahigh-temperature medical solid waste conversion, and the system for producing hydrogen oil through ultrahigh-temperature medical solid waste conversion is used for recovering medical solid waste and then carrying out ultrahigh-temperature gasification to generate mixed gas. Hydrogen and carbon dioxide are prepared from the mixed gas through a reforming reaction and a water-gas shift reaction under the action of a high-selectivity reaction catalyst, purified hydrogen is prepared from the hydrogen through a gas purification process, and hydrogen oil which can be stored at normal temperature and normal pressure is obtained through a hydrogenation reaction of the purified hydrogen and a liquid organic hydrogen storage carrier. According to the comprehensive utilization system for the medical solid waste, various pollution sources generated in the treatment process of the medical solid waste can be fundamentally eradicated, the requirements of all environmental protection standards in the world at present are met, the medical solid 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 present invention belongs to the field of hydrogen energy technology, particularly relates to an ultra-high temperature medical solid waste conversion method and system to hydrogen oil. Background [0002] Medical solid waste is different from ordinary living solid waste, which has strong spatial infection, acute infection and latent infection and other characteristics, if not properly handled, not only can cause pollution of water, soil, atmosphere, and even lead to the epidemic and outbreak of human and animal infectious diseases, and is likely to become the source of epidemic diseases. At present, among the many medical solid waste treatment methods used internationally, only the high temperature incineration treatment method has a wide range of adaptation to medical solid waste, the medical solid waste after treatment is difficult to identify, disinfection and sterilization thoroughly, so that the organic matter in the waste is converted into inorga...
