Abstract
Coke related catalyst deactivation is still attractive for many researchers as the complexity of carbon precursor. Y-zeolite is one of the most popular catalyst used in petrochemical industry, which is also progressively degrading by coking. In this piece of work, the effects of volatilization/decomposition temperature and sample-to-catalyst ratio on the coke formed from heavy oil volatilization/decomposition in the presence of Y-zeolite catalyst have been investigated. Temperature plays a significant role in determining the nature of the carbon formed, with higher temperatures favouring a higher graphitic-to-amorphous carbon ratio. Higher sample-to-catalyst ratios lead to higher amounts of coke, but does not affect the graphitic-to-amorphous carbon ratio as the same volatilization/decomposition temperature.
