B01J19/2455 - CPC Classification

Classification description:

Chemical, physical or physico-chemical processes in general; Their relevant apparatus; Stationary reactors without moving elements inside provoking a loop type movement of the reactants

Sub-classes:

B01J19/246 » {internally, i.e. the mixture circulating inside the vessel such that the upward stream is separated physically from the downward stream(s)} 60
B01J19/2465 » {externally, i.e. the mixture leaving the vessel and subsequently re-entering it} 220
