Criterion, part of Shell Group, is a multinational company manufacturing hydroprocessing catalysts for a wide range of refining applications.

Product range

Criterion supplies catalysts for the critical processes that use hydrogen to upgrade and add value to refinery streams and final products.

Our portfolio includes hydroprocessing catalysts for a wide variety of applications throughout the refinery, from ultra-low-sulphur diesel (ULSD) production to tail-gas treatment. We are heavily involved with hydrocracking, where we provide both feed pretreatment and cracking catalysts. We lead the industry in catalysts that are used for residue upgrading in both fixed- and ebullated-bed reactors.
