zeolite catalyst

zeolite catalyst

[′zē·ə‚līt ′kad·əl·əst]
(inorganic chemistry)
Hydrated aluminum and calcium (or sodium) silicates (for example, CaO·2Al2O3·5SiO2 or Na2O·2Al2O3·5SiO2) made with controlled porosity; used as a catalytic cracking catalyst in petroleum refineries, or loaded with catalyst for other chemical reactions.

c) NiW-supported zeolite catalyst promotes the hydrocracking of heavy oil in a much better and controlled manner.
In one of our previous works [13], we evaluated the impact of different hydrothermal treatments on a commercial copper-exchanged zeolite catalyst and we developed a model able to predict the evolution of ammonia adsorption and desorption under aging conditions.
Zeolite catalyst structure collapse is deemed to be the most likely aging mechanism causing the degradation of the catalyst though this had not been verified under the current study.
Utilization from Banana peel uses can be achieved as a promoter of zeolite catalyst follows:
The new process uses a zeolite catalyst capable of transforming glucose into p-xylene in a three-step reaction within a high-temperature biomass reactor.
While it has likely cost Cummins some business--as its single biggest heavy truck engine customer, Navistar, has firmly rejected SCR and will field the only truck manufactured in North America to offer EGR-only engines--Charlton said it was clear that the company's decision to change, prompted by better-than-expected performance from its copper zeolite catalyst technology being used in midrange, was the right one.

The process involves the hydrocarbon molecules being smashed by hydrogen atoms under pressure, at high temperature and with a zeolite catalyst.
of Cambridge and Imperial College in London have used similar software modeling techniques to explain the action of a zeolite catalyst used for petroleum production.

Cummins had established SCR as its 2010 solution for its midrange engine products and it was the progress of that midrange development--particularly in regards to emerging copper zeolite catalyst technology--that prompted Cummins to rethink its plans on the heavy-duty side.
