Class Information
Number: 585/735
Name: Chemistry of hydrocarbon compounds > Saturated compound synthesis > By isomerization > Using temperature gradient or material concentration gradient or introduction of same material at more than two serially spaced points of reaction zone system
Description: Subject matter wherein feedstreams of a material, e.g., a catalyst, feedstock, recycle material, etc., which can be considered as coming directly from the same source, that is, having the same composition, are introduced to an isomerization reaction zone system at more than two points spaced along the flow path of the reactant materials, or in which temperature conditions or the concentration of materials in the reactor is stated as changing gradually in space, that is, in the flow path of materials through a reaction zone from inlet to outlet, or in time, that is, from the moment that the reactor is put on stream until it is taken off stream.
