The operation of reforming catalysts in a fixed bed reactor undergoes high level interaction between the operating parameters and reaction mechanism. Understanding such an reduces catalyst deactivation rate. In present work, three kinds nanocatalysts (i.e., Pt/HY, Pt-Zn/HY, Pt-Rh/HY) were synthesized. catalysts’ performances evaluated for n-heptane reactions reactor. conditions applied followin...

Here we report a magnetic composite nanocatalyst (MP@NiSiO/Pd) with a rattle type nanostructure. The nickel silicate shell encapsulated magnetic core (MP@NiSiO) rattle particles were synthesized by using a facile templating method and the Pd nanocrystals with different sizes can be directly immobilized onto the MP@NiSiO rattles without using any surfactant or capping reagents. X-Ray powder Diff...
