Effect of two-component amorphous silica-alumina (ASA) with different Si/Al molar ratios on hydrocracking reactions for increasing naphtha over NiW/USY-ASA

The combination of ASA-0.4 and ASA-2 produces new acidic OH groups by increasing the contact points between silicon and aluminum. These OH groups improve the density of acid sites and increases the area of the active adsorption area of the support.
