According to the report of the MIT Technical Review magazine website on July 23, BASF developed a more environmentally friendly hydrogen production method and used homemade catalysts to combine the obtained hydrogen with carbon dioxide. Manufacturing chemicals and fuels. The new method can not only obtain more pure hydrogen, but also help reduce carbon dioxide emissions and promote the development of fuel cell vehicles.
Hydrogen-powered cars are considered to be more environmentally friendly options than natural gas-powered cars, but they also have problems: People generally use fossil-fuel natural gas to make hydrogen, and this process releases a lot of carbon dioxide.
Now BASF stated that they may have found a solution. The company is developing a process that will reduce carbon dioxide emissions by half, which will make hydrogen fuel cell vehicles more environmentally friendly than electric vehicles in many places (electric vehicles will involve the issue of how electricity is produced). In addition to providing more environmentally friendly hydrogen for fuel cell vehicles, the latest process will also benefit many industrial processes, including those that require the use of large quantities of hydrogen.
The more environmentally friendly method of hydrogen production is expected to rekindle people’s interest in fuel cell vehicles. Many automakers have already planned to start selling fuel cell vehicles as early as 2015.
In the traditional hydrogen production process, people generally react methane or water, which is the main component of natural gas, to produce hydrogen and carbon dioxide. It has long been known that hydrogen can also be produced without the introduction of oxygen (to avoid the production of carbon dioxide). At temperatures high enough, methane produces hydrogen and solid carbon (which can be used in industries such as steel manufacturing), but people have not been able to prove that this process is economically viable.
This is partly due to the fact that obtaining high temperatures requires a lot of energy, and that the production of these energy sources also emits large amounts of carbon dioxide. BASF found a better way to recycle the heat in the system, which greatly reduced the need for energy. The company's project coordinator Andreas Bode said: "This hydrogen production process has a cost advantage and also reduces carbon dioxide emissions."
BASF will cooperate with ThyssenKrupp Steel in Germany to use the carbon produced in this process for steel manufacturing.
At the same time, BASF is creating a demonstration plant to demonstrate this technology. This technology is part of a project (the German government provided $30 million in funding for the project). The second part of the project is to use the catalyst developed by BASF to combine the generated hydrogen with carbon dioxide to produce syngas (a mixture of carbon monoxide and hydrogen) for the production of methane, other chemicals and fuels. Although this basic reaction was known very early, BASF believes that its catalyst makes it economically viable. Bode said: "This is really a breakthrough." (Liu Xia)
The Pdc Bit Breaker and Tricone Bit breaker /rock Bit Breaker are suitable to make up or break out the drilling bit during the oil well driling and repairing operations.The users should be chosen the bit breaker according to the size and model of the drilling bit.
Bit Breaker are designed to contact the correct surface of tricone bit and PDC Bit , thus avoding damage to cones, bit legs or bearing when breaking out bits
1. Bit Breaker is mainly used to screw on or off a rock bit to the bottom of drilling string
2. It can also prevent the rock bit from dropping into well hole
3. The price is cheap and the use is safety and reliable
4. It is easy to operate, first the bit breaker is placed on well hole and then put the rock bit onto it, turn it to screw on or off the bit by turn plat
