Description
Technical Field
The utility model relates to the technical field of hydrogen production equipment, in particular to an alcohol fuel reformer for on-line hydrogen production.
Background
With the rapid development of social economy and the continuous improvement of the living and industrial levels of people in China, the energy consumption is rapidly increased, so that limited energy resources are increasingly deficient, the problems of energy and environment are more obvious, and the energy conservation, emission reduction and low-carbon development are inevitable trends of energy development in China and require that people have higher and higher call for seeking new energy (alternative energy) and green. How to accelerate the transformation of an energy consumption structure to clean low carbon and improve the development and utilization of renewable energy is a problem to be urgently solved.
As biomass energy in renewable energy, alcohol fuel (mainly methanol and ethanol) is a substitute fuel with great development potential. The methanol can be prepared from plant straws of corn, sugarcane and the like by a biological method, and can also be prepared by carbon capture and utilization and regeneration. In China, a large amount of methanol is mainly prepared from coal, natural gas and other minerals through a chemical and physical method. The ethanol is mainly prepared by fermenting crops containing sugar and starch or waste crops containing cellulose. Although alcohol fuels have high latent heat of vaporization and are rich in oxygen, direct combustion can better reduce emissions and achieve complete combustion. But at the same time their high latent heat of vaporization makes starting engines using alcohol fuels difficult at low temperature conditions. The alcohol fuel has very low cetane number, poor ignition performance, low saturated vapor pressure and other advantages, so that corresponding technical measures are required to be adopted for better use on a diesel engine.
The hydrogen is used as a clean energy and good energy carrier, has higher heat value, is clean and efficient, and can store energy. Compared with hydrocarbon, hydrogen has higher laminar flame propagation speed and shorter quenching distance, can ensure more complete combustion, expands the limit of lean flammability and is more beneficial to low-temperature starting. This is well demonstrated by existing loading theory and experimental studies on engines.
