Chemical processes

Ammonia cracking is the process by which ammonia is decomposed towards hydrogen and nitrogen over a catalyst (based on base or pgm metals).

Methanol synthesis is the formation of methanol from carbon oxides and hydrogen. It is catalysed by copper-zinc catalysts. KATALCO 51-series methanol synthesis catalysts are key to the methanol technologies offered by Johnson Matthey.

We offer catalysts for selective hydrogenation, for both ethylene plant configurations: front-end and tail-end.

INTERCAT addition systems have been in widespread use on the FCC process since the mid 1980’s, and today there are over 300 units installed in refineries throughout the world.

Aldolization is a key part of the oxo alcohols process where two aldehydes combine to produce a larger aldehyde which is then converted to an alcohol by hydrogenation.

Our amination catalysts are used for a variety of speciality amines production and downstream of our oxo-alcohol catalysts.

Amines are compounds derived from ammonia and contain a nitrogen atom with a lone electron pair. Amination is the process by which an amine group is added to an organic compound.

Johnson Matthey supplies both un-reduced and pre-reduced ammonia synthesis catalysts, based on more than 80 years' operating experience with ICI.

The PURASPEC product range contains a specially designed absorbent which is selective for the removal of arsine from natural gas streams. PURASPEC material is proven in the field for the last 15 years for arsine removal from natural gas streams.

Johnson Matthey’s DAVY™ biodiesel process offers a solution to this problem. Our flowsheet can employ inexpensive low-quality non-edible feeds, in addition to virgin and higher-quality oils.
