Molecular Highway technology has broad applicability and value to the refining industry. Many refining processes utilize zeolite catalysts and additives.

Nov 2, 1971 - During the course of the hydrocracking reaction the organic nitrogen may, because in some instances of itS basic nature, attack the acidic sites. Improvements to hydrocracking catalyst activity and selectivity at various operational. (HDN) activity advantage on a full- range VGO. Reaction environment.

But the diffusion limits of these materials is a limiting factor, constraining reaction rates, yields, and ultimately refinery profitability. When applied to catalysts and additives in FCC, hydrocracking, alkylation, or dewaxing units, Molecular Highway technology creates a network of broad channels that allows feed molecules rapid access into and out of the active catalytic sites in the zeolite. The enhanced access – or improved diffusion – leads to better product yields and product quality and opens up new routes to profitability, such as processing more barrels or running heavier feeds. FCC 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, naphtha, 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. Naruto episode 1 220 torrent. 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, 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 available from Rive and W.R.

As the worldwide demand for diesel fuel and high octane gasoline has grown, so too has the demand for hydrocracking catalysts. The enhanced accesses into and out of the zeolite provided by Rive’s Molecular Highway technology can overcome diffusional limits resulting in enhanced product yields of middle distillates. ALKYLATION The reaction of light paraffins with olefins is an important source of high quality, high octane gasoline in the modern refinery. Alkylation units are capital intensive and complex to operate. The complexity is heighted by the use of sulfuric acid or hydrofluoric acid as a catalyst.

Both acids present safety and environmental concerns and require extra vigilance during operation. Much work is thus underway to develop safer solid acid zeolite catalysts for use in this application. Rive’s Molecular Highway technology is another tool to advance the development of new zeolite based catalysts for alkylation. DEWAXING Utilizing either a hydrocracking or hydroisomerization reaction in tandem with a zeolite catalyst, catalytic dewaxing is a process utilized in refining, lubes production, and gas-to-liquid production to improve the flow characteristics of diesel fuel and lubricating oils in cold weather. The controlled introduction of larger pores to the zeolite, made possible with Molecular Highway technology, may lead to even more effective dewaxing catalysts.
