Scientists and Researchers of the University Of Wyoming have found out that pulverised coal powder that is being used in copper foil, glass containers and a household microwave can be converted into a higher-value nano-graphite. This discovery works as an alternative method for the usage of Wyoming’s Powder River Basin coal at this time when the demand for coal is causing electricity to gradually decrease due to a drastic climatic change.
Researchers have invented a new technology where they created a suitable environment in a microwave oven which could help in the conversion of raw coal powder inti nano-graphite. This “ONE-STEP METHOD” is a new way of representing a very simple inexpensive coal conversion technology.
In this new method, the researchers used simply ground raw Powder River Basin coal into powder. The powder was then put down on a copper foil and then sealed in glass containers with a gas mixture of argon and hydrogen before it is placed in an oven. The sparks which are duly caused by the microwave oven can necessarily transform coal powder into polycrystalline graphite in which the copper foil and hydrogen gas contribute in the particular process. The microwave extension ranges from 3 to 45 minutes and the foremost range is 15 minutes.
The researchers concluded that this particular method of coal conversion could be refined and accomplished at a very large scale to yield both higher quality and quantity of nano-graphite material.
