Our fluid catalytic cracking (FCC) additives and addition systems are used in more refineries globally than any other FCC additive products, optimising LPG yield, decreasing bottoms yields, controlling regenerator afterburn and reducing SOx and NOx emissions from the FCC unit.

Most refiners now find it essential to use catalytic additives to supplement the FCC catalyst to achieve desired unit performance, product quality, and environmental emissions targets.

We are the foremost supplier of FCC additives and addition systems, specialising in the development, manufacture, sale, and technical support of both additives and addition systems for the refining industry. Our comprehensive range of FCC additives and addition systems allow refiners the flexibility to continuously optimise product yields and properties, and minimise emissions.

NOx reduction FCC additives

NONOX™ focuses on selectively converting the precursors that go on to form NOx to N₂ and has been proven to attain up to 50% reduction in NOx when used at up to 2 wt% in the catalyst inventory with reductions in NOx realised in less than 24 hours.

Performance additives

Propylene butylene and octane improvement additives

Refinery profitability can be maximised by selectively choosing the proper ZSM-5 type additive. Johnson Matthey additives may be used at very high concentrations to provide a simple and effective route for adjusting FCC LPG olefin production to meet changing market demands.

Catalyst enhancement FCC additive

CAT-AID™, Johnson Matthey’s catalyst enhancement FCC additive, is designed to overcome many of the shortcomings related to deactivation of base catalyst from metal contaminants such as vanadium, nickel, iron, calcium, sodium, and potassium.

CO oxidation FCC additives

The physical properties of Johnson Matthey’s CO promoters, including particle size distribution, attrition resistance and bulk density, have been optimised to be fully compatible with all commercially available FCC unit designs and catalyst technologies. Independent testing has shown that INTERCAT CO promoters have the highest CO conversion efficiency on the market.

Addition systems

Johnson Matthey's addition systems have been in widespread use on the FCC process since the mid-1980s, and today there are over 400 units installed in refineries throughout the world. Our fresh catalyst addition systems are recommended for new FCCs by licensors Technip Stone & Webster, Axens, UOP and Lummus.
