Mostly in remote areas and for small gas fields, pipeline transportation of natural gas through the set up is a matter of financial trouble and expensive. First of all, coal or natural gas to extract natural gas sandstone itself will spend a lot of financial and material resources. Furthermore, exploitation of these finally out of gas transportation through pipelines, the cost will be very high.
Recently, the German Max Planck Institute (MaxPlanckInstitute) subsidiary Coal Research Center at the Max Planck Institute of Colloid and Interface Chemistry, the answer is to slowly emerge. Max Planck Institute researchers have developed a new solid catalyst, it can be in a Economy And effective way to make the methane into a liquid Methanol , While the transport of methanol is much easier than gaseous methane, while liquefaction costs lower than traditional methods. Thus, those who build natural gas pipeline without the high cost of gas fields have been developed had been re-developing the site.
To this end, the Max Planck Institute have developed a catalyst, the main ingredient is nitrogen-containing nickel-based alloys (CTF). Max Planck Institute of Colloid and Interface Chemistry, researchers Marcus? Anthony Diti said: "This has a strong penetration of solid materials, the surface area per gram of material equal to 1 / 5 the size of football field." CTF large surface area so that the material can be effectively adopted by the methane oxidation reaction, and transformed into methanol. In CTF the role of catalyst and sulfuric acid, through 215 degrees of heat and pressure, methane gas can be converted into methanol, the conversion of 3 / 4.
Ferdi? Schutte that they have developed a catalyst for even more low-cost, technology and more simple, easy to operate at the same time more efficient. However, Schutte and colleagues do not stop there, to expand the application scope of the catalyst [link widoczny dla zalogowanych], and now they are studying how to make a gaseous catalyst, "We are trying to find a similar, or more efficient catalyst, we have found more of choice. "
In fact, how to more economical and efficient manner the issue of liquefied methane, other scientists have been working hard. American chemist Roy? Puliyina once 10 years ago and developed a platinum catalyst material, the catalyst also can convert methane into methanol, but the catalyst can only play a role in the dissolved state, after the clean-up process is very cumbersome.
Schutte and colleagues of the research topic is how to make natural gas liquefaction process more "save money", which really reduce the cost of extracting natural gas.
Although there has been able to Chemical industry Means liquefied natural gas [link widoczny dla zalogowanych], methanol, greatly reducing transportation costs. However, Max-Planck-Institute for Coal Research Center Director Ferdi? Schutte view, although this approach reduces transportation costs, but the liquefaction process has brought a new spending, "There are the usual method of first gas changes into steam, and then synthetic technology to be translated into ethanol, to do so itself takes a lot of money. "
ple's Network Information, scientists predict [link widoczny dla zalogowanych], the world Natural gas Resources will be exhausted in 130 years, but if taking into account the cost of mining, human beings can only truly be able to use natural gas for about 60 years. How do those mining difficult, high cost of natural gas resources, "Resurrection", has become a hot topic of concern to the scientific community.
