Recently, China's largest single-production hydrogen production plant started construction at Sinopec (600028) Maoming Petrochemical. The device uses the most mature coal gasification (000968) technology in the world to convert coal or coke feedstock into hydrogen, which can save 20% to 25% compared with traditional hydrogen production processes.
The 200,000 standard cubic meters/hour coal hydrogen production plant is one of the important supporting projects for the 20 million-ton refinery expansion and expansion project of Sinopec Maoming Petrochemical. It is reported that this set of coal hydrogen production unit uses the gasification process of the United States General Electric Energy Group to convert coal or coke raw materials into crude synthesis gas, and then produce hydrogen. The technology has been applied in Sinopec Jinling Petrochemical, Qilu Petrochemical, and Nanhua.
China's coal resources are relatively abundant, and hydrogen production from coal is the main form of hydrogen production in China at this stage. The hydrogen production technology of coal mainly includes two kinds of hydrogen production from coal coking and hydrogen production from coal gasification, and hydrogen production from gasification. Industry insiders believe that compared with the traditional oil route, fuel produced from coal to produce fuel cells has the highest energy efficiency. Taking into account the development of hydrogen fuel cell technology in the future, coal hydrogen production technology will be an important development and application direction.
Robot has been used widely in modern industry. With the deeply urge for automation in grinding field, robot has been a smart mehtod to realize grinding automation. Our Force Control System connects with robot, can work in grinding polishing sanding, high working efficiency, low cost and cleaning working environment. More and more manufacturers choose this method to realize automation reform. So this method has been used in metal,plastics,acrylic, wood, compound material processing in 3c, household sanitary ware, auto parts, transportation tools etc.
