Abstract

See full text

A method of processing light fraction tar includes pre-heating the light fraction tar before directing it through a reactor. The reactor has a top and a bottom and a surface spanning between said top and said bottom. A film of the light fraction tar flows down the surface under the force of gravity and with heated gas blowing thereon. The portion of the film that reaches the bottom of the reactor has improved properties making it more widely useful for carbon products.
