Methanol Reforming Hydrogen Generation Unit /Natural Gas Ref
China is rich in coal resources, and methanol production from coal alone can ensure China's energy security for one hundred years. In the future, methanol can also be made from biomass and crop straw.
As of 2016, the global methanol production capacity is about 129 million tons/year, and China's methanol production capacity is 80 million tons/year, accounting for more than 60% of the world's production.
China is still steadily increasing the construction of methanol industry, with an estimated additional capacity of 20 million tons in the future.
The production technology is mature and the cost is lower than that of gasoline and diesel.
Methanol steam reforming for hydrogen production is the first choice for small and medium-sized hydrogen production
Compared with large-scale natural gas hydrogen production or water electrolysis hydrogen production, methanol steam reforming has lower investment and energy consumption. Because of the low reaction temperature (230C~280C), the process conditions are mild and the fuel consumption is low. Compared with the natural gas hydrogen plant of the same scale, the energy consumption of methanol steam conversion is about 50% of that of the former.
The raw material of methanol steam reforming for hydrogen production is easy to obtain, transport and storage. It is more suitable for general use in conventional environment. Because methanol contains C and O atoms in the form of carbon monoxide, a small amount of carbon dioxide (colorless, can only be measured by instrument) can be separated from the field hydrogen power generation and evaporated with deionized water. It is safer to use methanol to extract hydrogen for power generation than to use high-pressure bottled hydrogen directly. Especially for standby power supply of communication base station and emergency power generation, maintenance personnel prefer to use liquid gas without pressure.
Hydrogen production from reforming of fossil fuels including petroleum, coal and natural gas is the main source of hydrogen. Compared with hydrogen production from reforming of other fossil fuels, hydrogen production from reforming of natural gas has the advantages of less environmental pollution, high hydrogen content, economy, mature technology, safety and reliability, and perfect supply infrastructure. It can not only centralize hydrogen production, but also produce hydrogen on site, which is not the source of hydrogen for fuel cells. Wrong choice
