A recent study published in the British "Nature" magazine pointed out that: through, carbon dioxide (CO2) can be directly converted into storable synthetic fuel, this new technology will help to remove large amounts of CO2 in the atmosphere. Preliminary analysis shows that if this technology is adopted in the Commodity Fair Building in Frankfurt, Germany, the captured CO2 can produce 2,000 to 4,000 tons of fuel per year.
"Negative carbon emissions" technology is essential to maintain the stability of the future climate, but to suppress global warming, it is necessary to remove billions of tons of CO2, the amount is very large. At present, some feasible removal strategies are limited by industrial incentives and other factors, which are difficult to implement.
The joint research team of the University of Toronto in Canada and the Karlsruhe Institute of Technology (KIT) in Germany believes that the use of existing renewable energy-driven CO2 emission reduction technology to modify air-conditioning equipment can directly convert CO2 and moisture in the air on-site It is storable fuel.
The team assumed that the CO2 concentration in the atmosphere was 400 ppm (1 ppm = 1 part per million), and they estimated the CO2 removal rate in offices, shops, and homes based on the volume of circulating air, respectively. It was found that if this technology is used, the Frankfurt Trade Fair Building can remove up to 1.5 tons of CO2 per hour, and 25,000 shops in Germany can capture about 1,000 tons of CO2 per hour. If this technology is used at home, a 5-6 apartment building can capture 0.5 kg of CO2 per hour.
The researchers believe that this concept can motivate individuals to collect "synthetic oil" and turn it into self-use, similar to the use of solar panels to achieve distributed power generation.

Seamless Steel Pipe is so widely used. Most general purpose seamless Steel Pipe, mainly used by the ordinary carbon structural steel, low alloy steel or alloy steel rolling, yield transporting fluids or structural components.Seamless steel pipe production process can be divided into two kinds of cold-drawn and hot-rolled, cold-rolled seamless steel pipe production process is generally more complicated than hot-rolled, hot rolled Seamless Pipe diameter is generally greater than 32mm, wall thickness 2.5-200mm, rolled seamless steel pipe diameter can go to 6mm, wall thickness can be 0.25mm, thin-walled tube diameter to 5mm wall thickness of less than 0.25mm, cold than hot-rolled high dimensional accuracy.
