FCC catalysts powered by Molecular Highway technology enable feed molecules, such as VGO, resid or hydrotreated feeds, enhanced access to and exit from the active catalytic sites in the zeolite.  As a result, bulky feed molecules crack on the zeolite’s active sites, as opposed to on the less selective matrix material.  And valuable cracked products, such as distillate, naptha, and olefins, rapidly exit the zeolite cage before overcracking into undesirable byproducts like bottoms oil, coke and light gases.  As a result, refiners using catalysts powered by Molecular Highway technology make more of what they want, and less of what they don’t.  Refiners can take further advantage of the coke selectivity of Molecular Highway catalysts by running more barrels through the FCC and processing heavier feeds.

Refiners using catalysts powered by Molecular Highway technology can expect increased margin in the range of $.75 – $3.00 per barrel of FCC feed.  Benefits can be realized by simply switching catalysts.

FCC catalysts powered by Molecular Highway technology can be formulated and tailored for a specific refiner’s yield objectives, feed properties, and constraints.  The key physical properties of catalysts powered by Molecular Highway– namely stability, attrition resistance, fluidization – are similar to that of conventional catalysts.

Rive is commercializing FCC catalysts and ZSM-5 additives powered by Molecular Highway technology with W.R. Grace, the world’s leading supplier of FCC catalysts.  Molecular Highway FCC catalysts have been trialed successfully in two refineries in North America, and are currently from available from Rive and W.R. Grace.
