A Neuro-Fuzzy Algorithm for Modeling of Fischer-Tropsch Synthesis over a Bimetallic Co/Ni/Al2O3 Catalyst

An alumina supported Co/Ni catalyst was prepared by sol-gel procedure to study the catalytic behavior during Fischer-Tropsch synthesis in a fixed-bed reactor. The effect of CO conversion (10-50%) on hydrocarbon product distribution (CH4, C5+ and C2-C4 olefin selectivities) was studied. Selectivity for CH4 decreased, while those of C5+<...

Role of growth temperature in CVD synthesis of Carbon nanotubes from Ni-Co bimetallic catalysts

The effect of temperature variation on the growth of Carbon Nanotubes (CNTs) using Thermal Chemical Vapor Deposition (TCVD) is presented. Nickel and Cobalt (Ni-Co) thin films on Silicon (Si) substrates were used as catalysts in TCVD technique. Acetylene gas was used in CNTs growth process at the controlled temperature ranges from 850-1000 ̊ C. Catalysts and CNTs characterization was carried out ...

Understanding mixing of Ni and Pt in the Ni/Pt(111) bimetallic catalyst via molecular simulation and experiments.

Molecular dynamics (MD) simulations employing embedded atom method potentials and ultrahigh vacuum (UHV) experiments were carried out to study the mixing process between the Ni and Pt atoms in the Ni/Pt(111) bimetallic system. The barrier for a Ni atom to diffuse from the top surface to the subsurface layer is rather high (around 1.7 eV) as calculated using the nudged elastic band (NEB) method....
