CHEMICAL OR PHYSICAL PROCESSES, e.g. CATALYSIS OR COLLOID CHEMISTRY; THEIR RELEVANT APPARATUS

Description

B01J encompasses chemical and physical processes conducted on a laboratory or industrial scale, with particular emphasis on catalytic and colloid chemistry applications. This subclass covers reactors, reaction vessels, and apparatus designed for mixing, heating, cooling, and controlling conditions during chemical transformations, as well as methods for catalysis, heterogeneous reactions, and colloidal systems. The classification includes solid-liquid separation techniques relevant to process chemistry, such as filtration and centrifugation when integrated with chemical processing. B01J excludes apparatus solely dedicated to distillation (B01D), biochemical processes in dedicated bioreactors (C12M), and metallurgical processes (C22).
