Influence of the Copper Content of Catalyst on Performance
Publication: Journal of Energy Engineering
Volume 141, Issue 4
Abstract
A series of the mixed oxides were prepared by using the acid-processed gelatin method, characterized by Brunauer-Emmett-Teller (BET), X-ray diffraction (XRD), Fourier transform infrared (FT-IR), and transmission electron microscopy (TEM) techniques and applied as sulfur transfer catalysts under conditions similar to those of fluid catalytic cracking (FCC) units. The analysis of the abatement curves as a function of the copper content indicates that the reaction mechanism of uptake depends on two reversible surface processes (the chemisorptions of and its oxidation by copper ions) and a nearly irreversible process (bulk diffusion of the sulphate species). The results also show that the mixed oxides catalysts achieve the highest oxidative rate when they contain 11.1% (mol) copper (sample ).
