B01J CHEMICAL OR PHYSICAL PROCESSES, e.g. CATALYSIS OR COLLOID CHEMISTRY; THEIR RELEVANT APPARATUS
Introduced: September 1968
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).

Glossary
catalyst catalysts any substance that increases the rate of a reaction without itself being consumed. Catalysts are commonly used in their pure form or in combination with suitable carriers. chromatography a process in which a fluid is caused to flow along a linear path comprising a sorbent, with which the fluid competes in affinity for a constituent of the fluid. The constituent is sorbed from the moving fluid by the relatively immobile sorbent and re-dissolved by a later passing portion of the fluid until an equilibrium of the sorbing-dissolving step is set up causing the constituent to concentrate in a specific volume of the sorbent and to move along the path of the fluid at a rate slower than such fluid. fluidised particles fluidised particle finely divided solid particles lifted and agitated by a stream of fluid fluidised-bed fluidised beds fluidised-solid contacting technique in which finely divided particles are lifted and agitated by a rising stream of fluid molecular sieve molecular sieves materials (e.g. zeolitic or mesoporous) having cavities and channels which by their size allow some molecules to pass through, but prevent others solid particles solid particle particles whether catalysts, reactants or inert in solid, semi-solid or pasty state sorbent sorbents a material which separates a constituent from a fluid mixture containing such constituents. The action in most instances is that of selective retention (i.e. the sorbent removes only the part of the fluid mixture for which it has the greatest affinity). zeolites zeolite (i) crystalline aluminosilicates with base-exchange and molecular sieve properties, having three-dimensional [3D], microporous lattice framework structure of tetrahedral oxide units; (ii) compounds isomorphous to those of the former category, wherein the aluminium or silicon atoms in the framework are partly or wholly replaced by atoms of other elements, e.g. gallium, germanium, phosphorus or boron.
