Problems solved by technology

In addition, the power consumption of hydrogen production by electrolysis of water is about 5-8kW·h / m 3 ·H 2 , the unit cost of hydrogen is higher
In the fine chemical and pharmaceutical industries, there is a large demand for small and medium-scale hydrogen production, and the above hydrogen production methods are all less economical.

Abstract

The invention belongs to the technical field of hydrogen preparation. Specifically, the invention provides equipment for hydrogen production through reforming of methanol steam. The equipment comprises a liquid storage device, main hydrogen production equipment and a plurality of pieces of hydrogen production sub-equipment, wherein the main hydrogen production equipment obtains hydrogen and conveys discharged residual gas into one piece of hydrogen production sub-equipment at the same time; and the sub-hydrogen production equipment receives residual gas discharged by the main hydrogen production equipment or / and other hydrogen production sub-equipment and uses the residual gas for continuously producing hydrogen. In addition, the invention also provides a method for hydrogen production through reforming of methanol steam by using the equipment. The technology of multiple residual gas reforming is adopted, so methanol cracking efficiency is further improved, harmful gas in the residual gas can be reduced, the concentration of hydrogen is improved, and the method is more environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of hydrogen preparation, and in particular relates to a hydrogen production equipment and method by steam reforming of methanol. Background technique [0002] The development of energy has always been the lifeline of the civilization and progress of human society. Hydrogen is called "energy currency". Its calorific value is second only to nuclear fuel, and it is three times the calorific value of gasoline. Hydrogen is also a non-toxic energy carrier, and does not produce greenhouse gases and other pollutants after combustion, which is very conducive to energy saving and emission reduction, so it is regarded as an ideal clean new energy in the 21st century. In recent years, due to the breakthrough and continuous development of proton exchange membrane fuel cell technology, hydrogen energy is one of the important bridges for the transition from fossil energy to renewable energy. At the same time, hydrogen is ...
