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.}, issn = {0165-2370}, author = {Zhang, Y and Owen, R and Shearing, P and Maskell, W and Brett, D and Manos, G}, keywords = {Volatilization/decomposition, Coking, Heavy oil, Y-Zeolite} }
