Effect of synthesis and activation methods on the character of CoMo/ultrastable Y-zeolite catalysts

The properties of three types of CoMo/USY catalysts with different synthesized methods have been studied. The sequential and co-impregnation methods followed by activation using calcination and reduction process have been conducted. The properties of the catalysts were examined using Fourier-transfo...
