(under the class definition) Processes in which the feed material is composed of two or more carbonaceous substances of which at least the predominate one is a solid.
(1) Note. For purposes of this and indented subclasses, garbage and waste material which is carbonized is considered a mixture unless the disclosure specifically states that it is not.
(2) Note. For purposes of this and indented subclasses wood, oil shale or a particular type of coal is considered a distinct material.
(3) Note. For purposes of this and indented subclasses a charge of a mixture of two distinct sizes of particles is
considered a mixture, e.g., a charge consisting of wood blocks and sawdust.
