Abstract
The invention provides a method for the production of graphene-structured products. The method generally comprises contacting at a conversion temperature ranging from about 850° C. to about 1100° C. in an inert atmosphere coal with a molten salt to produce a graphene-structured product. In an alternate embodiment, the method comprises contacting at a conversion temperature ranging from about 850° C. to about 1100° C. in an inert atmosphere coal with a molten salt to produce a graphene-structured product; and, separating a rare earth element from the graphene-structured product.
Claims27
A method for the production of a graphene-structured product, the method comprising:
- contacting at a conversion temperature ranging from about 850° C. to about 1100° C. coal with a molten salt to produce a graphene-structured product, wherein the contacting step further comprises combining the coal and molten salt to form a uniformly dispersed mixture of said coal and said molten salt.
A method for the production of graphene-structured product, the method comprising:
- contacting coal and molten salt, wherein the contacting step further comprises combining the coal and molten salt to form a uniformly dispersed mixture of said coal and said molten salt;
- heating the mixture through a temperature ranging from about 300° C. to about 700° C. to a conversion temperature ranging from about 850° C. to about 1100° C. to produce a graphene-structured product;
- and
- capturing a tailing gas produced from heating at a temp ranging from about 300° C. to about 700° C.
